Safety Instructions
What this Chapter Contains
This chapter contains the safety instructions which you must follow when installing,
operating and servicing the drive. If ignored, physical injury or death may follow, or
damage may occur to the drive, the motor or driven equipment. Read the safety
instructions before you work on the unit.
Use of Warnings and Notes
There are two types of safety instructions throughout this manual: warnings and
notes. Warnings caution you about conditions which can result in serious injury or
death and/or damage to the equipment. They also tell you how to avoid the danger.
Notes draw attention to a particular condition or fact, or give information on a
subject. The warning symbols are used as follows:
Dangerous voltage warning warns of high voltage which can cause
physical injury and/or damage to the equipment.
General warning warns about conditions, other than those caused by
electricity, which can result in physical injury and/or damage to the
equipment.
Electrostatic discharge warning warns of electrostatic discharge which
can damage the equipment.
Special note or recommendation. This symbol is used to highlight
especially important information or recommendation for product
application.
Safety Instructions
6
Installation and Maintenance Work
These warnings are intended for all who work on the drive, motor cable or motor.
Ignoring the instructions can cause physical injury or death.
WARNING!
•
Only qualified electricians are allowed to install and maintain the drive.
•
Never work on the drive, motor cable or motor when main power is applied.
After switching off the power, always wait for 5 minutes to let the intermediate
circuit capacitors discharge before you start working on the drive, the motor or
the motor cable.
Always ensure by measuring with a multimeter (impedance at least 1 Mohm)
that:
1. Voltage between drive input phases L1, L2 and L3 and the frame is close to
0 V.
2. Voltage between terminals UDC+ and UDC- and the frame is close to 0 V.
•
Do not work on the control cables when power is applied to the drive or to the
external control circuits. Externally supplied control circuits may cause
dangerous voltages inside the drive even when the main power on the drive is
switched off.
•
Do not make any insulation or voltage withstand tests on the drive or drive
modules.
•
When reconnecting the motor cable, always check that the phase order is
correct.
Note:
Safety Instructions
•
The disconnecting device (means) of the drive does not isolate the input cables
and busbars from the main AC supply. Before working inside the cabinet,
isolate the input cables and busbars from the main supply with the
disconnecting device at the distribution board or with the disconnector of the
supply transformer.
•
The motor cable terminals on the drive are at a dangerously high voltage when
the input power is on, regardless of whether the motor is running or not.
•
The brake control terminals (UDC+, UDC-, R+ and R- terminals) carry a
dangerous DC voltage (over 500 V).
•
Depending on the external wiring, dangerous voltages [115 V, 220 V or 230 V]
may be present on the terminals of relay outputs RO1 to RO3.
•
The Prevention of Unexpected Start function does not remove the voltage from
the main and auxiliary circuits.
7
WARNING!
•
Cover the drive when installing to ensure that dust from drilling or foreign
objects do not enter the drive. Electrically conductive dust inside the unit may
cause damage or lead to malfunction.
•
Ensure sufficient cooling.
•
Welding of the cabinet frame is not recommended. However, if electric welding
is the only way to mount the cabinet, follow the instructions given in chapter
"Mechanical Installation". Ensure that welding fumes are not inhaled. If the
welding return wire is connected improperly, the welding circuit may damage
electronic circuits in the cabinet.
•
When removing the module from the cabinet and maneuvering it outside the
cabinet, prevent it from toppling over by securing it. The drive module is heavy
and has a high center of gravity.
WARNING! The printed circuit boards contain components sensitive to electrostatic
discharge. Wear a grounding wrist band when handling the boards. Do not touch the
boards unnecessarily.
Safety Instructions
8
Grounding
These instructions are intended for all who are responsible for the grounding of the
drive. Incorrect grounding can cause physical injury, death or equipment malfunction
and increase electromagnetic interference.
WARNING!
•
Ground the drive, the motor and adjoining equipment to ensure personnel
safety in all circumstances, and to reduce electromagnetic emission and pickup.
•
Make sure that grounding conductors are adequately sized as required by
safety regulations.
•
In a multiple-drive installation, connect each drive separately to protective
earth (PE).
•
Do not install a drive with EMC filter option +E202 on an ungrounded power
system or a high resistance-grounded (over 30 ohms) power system.
Note:
•
Power cable shields are suitable for equipment grounding conductors only
when adequately sized to meet safety regulations.
•
As the normal leakage current of the drive is higher than 3.5 mA AC or 10 mA
DC (stated by EN 50178, 5.2.11.1), a fixed protective earth connection is
required.
Fiber Optic Cables
WARNING! Handle the fiber optic cables with care. When unplugging optic cables,
always grab the connector, not the cable itself. Do not touch the ends of the fibres
with bare hands as the fibre is extremely sensitive to dirt. The minimum allowed
bend radius is 35 mm (1.4 in.).
Safety Instructions
9
Operation
These warnings are intended for all who plan the operation of the drive or operate
the drive. Ignoring the instructions can cause physical injury or death or damage the
equipment.
WARNING!
•
Before adjusting the drive and putting it into service, make sure that the motor
and all driven equipment are suitable for operation throughout the speed range
provided by the drive. The drive can be adjusted to operate the motor at
speeds above and below the speed provided by connecting the motor directly
to the power line.
•
Do not activate automatic fault reset functions of the Standard Application
Program if dangerous situations can occur. When activated, these functions
will reset the drive and resume operation after a fault.
•
Do not control the motor with the disconnecting device (disconnecting means);
instead, use the control panel keys
and
, or commands via the I/O
board of the drive. The maximum allowed number of charging cycles of the DC
capacitors (i.e. power-ups by applying power) is five in ten minutes.
•
Do not use the optional Prevention of Unexpected Start function for stopping
the drive when the drive is running. Give a Stop command instead.
Note:
•
If an external source for start command is selected and it is ON, the drive (with
Standard Application Program) will start immediately after fault reset unless the
drive is configured for 3-wire (a pulse) start/stop.
•
When the control location is not set to Local (L not shown in the status row of
the display), the stop key on the control panel will not stop the drive. To stop
the drive using the control panel, press the LOC/REM key and then the stop
key
.
Safety Instructions
10
Permanent Magnet Motor
These are additional warnings concerning permanent magnet motor drives.
WARNING! Do not work on the drive when the permanent magnet motor is rotating.
Also, when the supply power is switched off and the inverter is stopped, a rotating
permanent magnet motor feeds power to the intermediate circuit of the drive and the
supply connections become live.
Installation and Maintenance Work
Before installation and maintenance work on the drive:
• Disconnect the motor from the drive with a safety switch
and additionally if possible (or)
• lock the motor shaft and ground the motor connection terminals temporarily by
connecting them together as well as to the PE. Before grounding, measure that
the motor is de-energized.
Operation
Do not run the motor over the rated speed. Motor overspeed leads to overvoltage
which may explode the capacitors in the intermediate circuit of the drive.

Planning the Electrical Installation
What this Chapter Contains
This chapter contains the instructions that you must follow when selecting the motor,
cables, protections, cable routing and way of operation for the drive system. Always
follow local regulations.
Note: If the recommendations given by ABB are not followed, the drive may
experience problems that the warranty does not cover.
To Which Products this Chapter Applies
This chapter applies to the ACS800-01/U1, ACS800-02/U2, ACS800-04/U4,
ACS800-PC, and ACS800-07/U7 types up to -0610-X.
Motor Selection and Compatibility
1. Select the motor according to the rating tables in chapter Technical Data. Use the
DriveSize PC tool if the default load cycles are not applicable.
2. Check that the motor ratings lie within the allowed ranges of the drive control
program:
• Motor nominal voltage is 1/2 … 2 · UN of the drive
• Motor nominal current is 1/6 … 2 · I2hd of the drive in DTC control and
0 … 2 · I2hd in scalar control. The control mode is selected by a drive parameter.
3. Check that the motor voltage rating meets the application requirements:
• The motor voltage is selected according to the AC voltage feeding the drive when
the drive is equipped with a diode input bridge (a non-regenerative drive) and will
operate in motor mode (i.e. no braking).
• The motor nominal voltage is selected according to “the equivalent AC power
source voltage of the drive” if the intermediate DC circuit voltage of the drive is
increased from the nominal level by resistor braking or by the control program of a
regenerative IGBT line-side converter (parameter selectable function).
The equivalent AC power source voltage for the drive is calculated as follows:
UACeq = UDCmax/1.35
where
UACeq = equivalent AC power source voltage of the drive
UDCmax = maximum intermediate DC circuit voltage of the drive
See notes 6 and 7 below the "Requirements Table".
Planning the Electrical Installation
30
4. Consult the motor manufacturer before using a motor in a drive system where the
motor nominal voltage differs from the AC power source voltage.
5. Ensure that the motor insulation system withstands the maximum peak voltage in the
motor terminals. See the "Requirements Table" below for the required motor
insulation system and drive filtering.
Example: When the supply voltage is 480 V and the drive is operating in motor
mode only, the maximum peak voltage in the motor terminals can be approximated
as follows: 480 V · 1.35 · 2 = 1296 V. Check that the motor insulation system
withstands this voltage.
Protecting the Motor Insulation and Bearings
The output of the drive comprises – regardless of output frequency – pulses of
approximately 1.35 times the equivalent mains network voltage with a very short rise
time. This is the case with all drives employing modern IGBT inverter technology.
The voltage of the pulses can be almost double at the motor terminals, depending on
the attenuation and reflection properties of the motor cable and the terminals. This in
turn can cause additional stress on the motor and motor cable insulation.
Modern variable speed drives with their fast rising voltage pulses and high switching
frequencies can generate current pulses that flow through the motor bearings, which
can gradually erode the bearing races and rolling elements.
The stress on motor insulation can be avoided by using optional ABB du/dt filters.
du/dt filters also reduce bearing currents.
To avoid damage to motor bearings, the cables must be selected and installed
according to the instructions given in the hardware manual. In addition, insulated Nend (non-driven end) bearings and output filters from ABB must be used according
to the following table. Two types of filters are used individually or in combinations:
• Common mode filter (mainly reduces bearing currents).
• du/dt filter (protects motor insulation system and reduces bearing currents).
Planning the Electrical Installation

Requirements Table
The following table shows how to select the motor insulation system and when an
optional ABB du/dt filter, insulated N-end (non-driven end) motor bearings and ABB
common mode filters are required. The motor manufacturer should be consulted
regarding the construction of the motor insulation and additional requirements for
explosion-safe (EX) motors. Failure of the motor to fulfill the following requirements
or improper installation may shorten motor life or damage the motor bearings.

Planning the Electrical Installation
33
Note 6: Resistor braking of the drive
When the drive is in braking mode for a large part of its operation time, the
intermediate circuit DC voltage of the drive increases, the effect being similar to
increasing the supply voltage by up to 20 percent. The voltage increase should be
taken into consideration when determining the motor insulation requirement.
Example: Motor insulation requirement for a 400 V application must be selected as if
the drive were supplied with 480 V.
Note 7: Drives with an IGBT supply unit
If voltage is raised by the drive (this is a parameter selectable function), select the
motor insulation system according to the increased intermediate circuit DC voltage
level, especially in the 500 V supply voltage range.
Permanent Magnet Synchronous Motor
Only one permanent magnet motor can be connected to the inverter output.
It is recommended to install a safety switch between the permanent magnet
synchronous motor and the motor cable. The switch is needed to isolate the motor
during any maintenance work on the drive.
Supply Connection
Disconnecting Device (Disconnecting Means)
ACS800-01, ACS800-U1, ACS800-02, ACS800-U2 without enclosure extension,
ACS800-04, ACS800-U4
Install a hand-operated input disconnecting device (disconnecting means) between
the AC power source and the drive. The disconnecting device must be of a type that
can be locked to the open position for installation and maintenance work.
ACS800-U2 with enclosure extension, ACS800-07, ACS800-U7, and ACS800-PC
These units are equipped with a hand-operated input disconnecting device
(disconnecting means) which isolates the drive and the motor from the AC power as
standard. The disconnecting device does not, however, isolate the input busbars
from the AC power. Therefore during installation and maintenance work on the drive,
the input cables and busbars must be isolated from the input power with a
disconnector at the distribution board or at the supplying transformer.
US
The disconnecting means must conform to the applicable safety regulations.
Fuses
See section "Thermal Overload and Short-Circuit Protection".
Planning the Electrical Installation
34
Thermal Overload and Short-Circuit Protection
The drive protects itself and the input and motor cables against thermal overload
when the cables are dimensioned according to the nominal current of the drive. No
additional thermal protection devices are needed.
WARNING! If the drive is connected to multiple motors, a separate thermal overload
switch or a circuit breaker must be used for protecting each cable and motor. These
devices may require a separate fuse to cut off the short-circuit current.
The drive protects the motor cable and motor in a short-circuit situation when the
motor cable is dimensioned according to the nominal current of the drive.
Mains Cable (AC Line Cable) Short-Circuit Protection
Always protect the input cable with fuses. Size the fuses according to local safety
regulations, appropriate input voltage and the rated current of the drive (see
Technical Data).
Drive AC Fuses (Standard on ACS800-PC)
ACS800-PC units are equipped with Fast Acting Current Limiting Class T (JJS-xxx)
fuses listed in Technical Data. The fuses restrict drive damage and prevent damage
to adjoining equipment in case of a short-circuit inside the drive.
Operating Time of the Fuses
Check that the operating time of the fuse is below 0.5 seconds. The operating
time depends on the fuse type, supply network impedance and the cross-sectional
area, material and length of the supply cable. In case the 0.5 seconds operating time
is exceeded with Class T fuses, ultrarapid (aR) fuses will in most cases reduce the
operating time to an acceptable level. The US fuses must be of the “non-time delay”
type.
For fuse ratings, see Technical Data.
WARNING! Circuit breakers must not be used without fuses.
Ground Fault Protection
The drive is equipped with an internal ground fault protective function to protect the
unit against ground faults in the motor and motor cable. This is not a personal safety
or a fire protection feature. The ground fault protective function can be disabled with
a parameter, refer to the appropriate ACS800 Firmware Manual.
The EMC filter of the drive includes capacitors connected between the main circuit
and the frame. These capacitors and long motor cables increase the ground leakage
current and may cause fault current circuit breakers to function.
Planning the Electrical Installation
35
Emergency Stop Devices
For safety reasons, install the emergency stop devices at each operator control
station and at other operating stations where emergency stop may be needed.
Note: Pressing the stop key ( ) on the control panel of the drive does not generate
an emergency stop of the motor or separate the drive from dangerous potential.
ACS800-02/U2 with Enclosure Extension, ACS800-07/U7, and ACS800-PC
An emergency stop function is optionally available for stopping and switching off the
whole drive. Two stop categories according to IEC/EN 60204-1 (1997) are available:
immediate removal of power (Category 0 for ACS800-02/U2, ACS800-07/U7, and
ACS800-PC) and controlled emergency stop (Category 1 for ACS800-07/U7).
Restarting after an emergency stop
After an emergency stop, the emergency stop button must be released and the drive
started by turning the operating switch of the drive from position “ON” to “START”.
Planning the Electrical Installation
36
Prevention of Unexpected Start (ACS800-07/U7 only)
The drive can be equipped with an optional Prevention of Unexpected Start function
according to standards IEC/EN 60204-1: 1997; ISO/DIS 14118: 2000 and EN 1037:
1996.
The Prevention of Unexpected Start function disables the control voltage of the
power semiconductors, thus preventing the inverter from generating the AC voltage
required to rotate the motor. By using this function, short-time operations (like
cleaning) and/or maintenance work on non-electrical parts of the machinery can be
performed without switching off the AC power supply to the drive.
The operator activates the Prevention of Unexpected Start function by opening a
switch on a control desk. An indicating lamp on the control desk will light, signalling
that the prevention is active. The switch can be locked out.
The user must install on a control desk near the machinery:
• Switching/disconnecting device for the circuitry. “Means shall be provided to
prevent inadvertent, and/or mistaken closure of the disconnecting device.”
EN 60204-1: 1997.
• Indicating lamp; on = starting the drive is prevented, off = drive is operative.
For connections to the drive, see the circuit diagram delivered with the drive.
WARNING! The Prevention of Unexpected Start function does not disconnect the
voltage of the main and auxiliary circuits from the drive. Therefore maintenance work
on electrical parts of the drive or the motor can only be carried out after isolating the
drive system from the main supply.
Note: When a running drive is stopped by using the Prevention of Unexpected Start
function, the drive will stop by coasting. If this is not acceptable (e.g. causes danger),
the drive and machinery must be stopped using the appropriate stopping mode
before using this function.
Planning the Electrical Installation
37
Selecting the Power Cables
General Rules
Dimension the mains (input power) and motor cables according to local
regulations:
• The cable must be able to carry the drive load current. See chapter Technical
data for the rated currents.
• The cable must be rated for at least 70 °C maximum permissible temperature of
conductor in continuous use. For US, see "Additional US Requirements".
• The inductance and impedance of the PE conductor/cable (grounding wire) must
be rated according to permissible touch voltage appearing under fault conditions
(so that the fault point voltage will not rise excessively when a ground fault
occurs).
• 600 VAC cable is accepted for up to 500 VAC. 750 VAC cable is accepted for up
to 600 VAC. For 690 VAC rated equipment, the rated voltage between the
conductors of the cable should be minimum 1 kV.
For drive frame size R5 and larger, or motors larger than 30 kW (40 HP),
symmetrical shielded motor cable must be used (figure below). A four-conductor
system can be used up to frame size R4 with up to 30 kW (40 HP) motors, but
shielded symmetrical motor cable is recommended.
Note: When continuous conduit is employed, shielded cable is not required.
A four-conductor system is allowed for input cabling, but shielded symmetrical cable
is recommended. To operate as a protective conductor, the shield conductivity must
be as follows when the protective conductor is made of the same metal as the phase
conductors:
Cross-sectional area of the phase
conductors
S (mm2)
Minimum cross-sectional area of the
corresponding protective conductor
Sp (mm2)
S < 16
S
16 < S < 36

35 < S
S/2
Compared to a four-conductor system, the use of symmetrical shielded cable
reduces electromagnetic emission of the whole drive system as well as motor
bearing currents and wear.
The motor cable and its PE pigtail (twisted shield) should be kept as short as
possible in order to reduce electromagnetic emission.

Alternative Power Cable Types
Power cable types that can be used with the drive are represented below.
Recommended
Symmetrical shielded cable: three phase conductors
and a concentric or otherwise symmetrically
constructed PE conductor, and a shield

and shield
A separate PE conductor is required if the conductivity
of the cable shield is < 50 % of the conductivity of the

Not allowed for motor cables
Not allowed for motor cables with phase
conductor cross section larger than 10 mm 2
[motors > 30 kW (40 HP)].
Motor Cable Shield
To effectively suppress radiated and conducted radio-frequency emissions, the
shield conductivity must be at least 1/10 of the phase conductor conductivity. The
requirements are easily met with a copper or aluminium shield. The minimum
requirement of the motor cable shield of the drive is shown below. It consists of a
concentric layer of copper wires with an open helix of copper tape. The better and
tighter the shield, the lower the emission level and bearing currents.

Additional US Requirements
Type MC continuous corrugated aluminum armor cable with symmetrical grounds or
shielded power cable must be used for the motor cables if metallic conduit is not
used. For the North American market, 600 VAC cable is accepted for up to 500 VAC.
1000 VAC cable is required above 500 VAC (below 600 VAC). For drives rated over
100 amperes, the power cables must be rated for 75 °C (167 °F).
Conduit
Where conduits must be coupled together, bridge the joint with a ground conductor
bonded to the conduit on each side of the joint. Bond the conduits also to the drive
enclosure. Use separate conduits for input power, motor, brake resistors, and control
wiring. When conduit is employed, type MC continuous corrugated aluminum armour
cable or shielded power cable is not required. A dedicated ground cable is always
required.
Note: Do not run motor wiring from more than one drive in the same conduit.
Armored Cable / Shielded Power Cable
The motor cables can be run in the same cable tray as other 460 V or 600 V power
wiring. Control and signal cables must not be run in the same tray as power cables.
Six conductor (3 phases and 3 ground) type MC continuous corrugated aluminum
armor cable with symmetrical grounds is available from the following suppliers (trade
names in parentheses):
• Anixter Wire & Cable (Philsheath)
• BICC General Corp (Philsheath)
• Rockbestos Co. (Gardex)
• Oaknite (CLX).
Shielded power cables are available from Belden, LAPPKABEL (ÖLFLEX) and
Pirelli.
Power Factor Compensation Capacitors
Do not connect power factor compensation capacitors or surge absorbers to the
motor cables (between the drive and the motor). They are not designed to be used
with drives, and will degrade motor control accuracy. They can cause permanent
damage to the drive or themselves due to the rapid changes in the drive output
voltage.
If there are power factor compensation capacitors in parallel with the three phase
input of the drive, ensure that the capacitors and the drive are not charged
simultaneously to avoid voltage surges which might damage the drive system.
Planning the Electrical Installation
40
Equipment Connected to the Motor Cable
Installation of Safety Switches, Contactors, Connection Boxes, etc.
To minimize the emission level when safety switches, contactors, connection boxes
or similar equipment are installed in the motor cable (i.e. between the drive and the
motor):
• EU: Install the equipment in a metal enclosure with 360 degrees grounding for the
shields of both the incoming and outgoing cable, or connect the shields of the
cables otherwise together.
• US: Install the equipment in a metal enclosure in a way that the conduit or motor
cable shielding runs consistently without breaks from the drive to the motor.
Bypass Connection
WARNING! Never connect the supply power to the drive output terminals U2, V2
and W2. If frequent bypassing is required, employ mechanically connected switches
or contactors. Mains (line) voltage applied to the output can result in permanent
damage to the unit.
Before Opening a Contactor (DTC Control Mode Selected)
Stop the drive and wait for the motor to stop before opening a contactor between the
output of the drive and the motor when the DTC control mode is selected. See the
appropriate ACS800 application program firmware manual for the required
parameter settings. Otherwise, the contactor will be damaged. In scalar control, the
contactor can be opened with the drive running.
Planning the Electrical Installation
41
Protecting the Relay Output Contacts and Attenuating
Disturbances in Case of Inductive Loads
Inductive loads (relays, contactors, motors) cause voltage transients when switched
off.
The relay contacts on the RMIO board are protected with varistors (250 V) against
overvoltage peaks. In spite of this, it is highly recommended to equip inductive loads
with noise attenuating circuits [varistors, RC filters (AC) or diodes (DC)] in order to
minimize the EMC emission at switch-off. If not suppressed, the disturbances may
connect capacitively or inductively to other conductors in the control cable and form
a risk of malfunction in other parts of the system.
Install the protective component as close to the inductive load as possible. Do not
install protective components at the RMIO board terminal block.

Selecting the Control Cables
All control cables must be shielded.
Use a double-shielded twisted pair cable for analog signals. This type of cable is
recommended for the pulse encoder signals also. Employ one individually shielded
pair for each signal. Do not use common return for different analogue signals.
A double-shielded cable is the best alternative for low-voltage digital signals but
single-shielded twisted multipair cable (Figure b) is also usable.
a
A double-shielded twisted
pair cable
b
A single-shielded twisted
multipair cable
Run analogue and digital signals in separate, shielded cables.
Relay-controlled signals, providing their voltage does not exceed 48 V, can be run in
the same cables as digital input signals. It is recommended that the relay-controlled
signals be run as twisted pairs.
Never mix 24 VDC and 115/230 VAC signals in the same cable.
Relay Cable
The cable type with braided metallic screen has been tested and approved by ABB.
Control Panel Cable
In remote use, the cable connecting the control panel to the drive must not exceed 3
metres (10 ft). The cable type tested and approved by ABB is used in control panel
option kits.
Planning the Electrical Installation
43
Connection of a Motor Temperature Sensor to the Drive I/O
WARNING! IEC 60664 requires double or reinforced insulation between live parts
and the surface of accessible parts of electrical equipment which are either nonconductive or conductive but not connected to the protective earth.
To fulfil this requirement, the connection of a thermistor (and other similar
components) to the digital inputs of the drive can be implemented in three alternate
ways:
1. There is double or reinforced insulation between the thermistor and live parts of
the motor.
2. Circuits connected to all digital and analog inputs of the drive are protected
against contact and insulated with basic insulation (the same voltage level as the
drive main circuit) from other low voltage circuits.
3. An external thermistor relay is used. The insulation of the relay must be rated for
the same voltage level as the main circuit of the drive. For connection, see
ACS800 Firmware Manual.
Routing the Cables
Route the motor cable away from other cable routes. Motor cables of several drives
can be run in parallel installed next to each other. When shielded or armored cable is
used, it is recommended that the motor cable, input power cable and control cables
be installed on separate trays. Avoid long parallel runs of motor cables with other
cables in order to decrease electromagnetic interference caused by the rapid
changes in the drive output voltage.
Where control cables must cross power cables make sure they are arranged at an
angle as near to 90 degrees as possible. Do not run extra cables through the drive.
The cable trays must have good electrical bonding to each other and to the
grounding electrodes. Aluminium tray systems can be used to improve local
equalizing of potential.
Note: When using conduit for motor cables, motors cables must be in separate
conduits for each motor. Do not run cables for more than one motor in one conduit.

What this Chapter Contains
This chapter describes the electrical installation procedure of the drive.
WARNING! Only qualified electricians are allowed to carry out the work described in
this chapter. Follow the "Safety Instructions" on the first pages of this manual.
Ignoring the safety instructions can cause injury or death.
Before Installation
IT (Ungrounded) Systems
A drive equipped with no EMC filter or with EMC filter +E210 is suitable for IT
(ungrounded systems). If the drive is equipped with EMC filter +E200 or +E202,
disconnect the filter before connecting the drive to an ungrounded system. For
detailed instructions on how to do this, please contact your local ABB representative.
WARNING! If a drive with EMC filter +E200 or +E202 is installed on an IT system [an
ungrounded power system or a high resistance-grounded (over 30 ohms) power
system], the system will be connected to earth potential through the EMC filter
capacitors of the drive. This may cause danger or damage the unit.
Electrical Installation
46
Checking the Insulation of the Assembly
Every drive module has been tested for insulation between the main circuit and the
chassis (2500 V rms 50 Hz for 1 second) at the factory. Therefore, do not make any
voltage tolerance or insulation resistance tests (e.g. hi-pot or megger) on any part of
the drive. Check the insulation of the assembly as follows.
WARNING! Check the insulation before connecting the drive to the mains. Make
sure that the drive is disconnected from the mains (input power).
1. Check that the motor cable is disconnected from the drive output terminals U2, V2
and W2.
2. Measure the insulation resistances of the motor cable and the motor between each
phase and the Protective Earth by using a measuring voltage of 1 kV DC. The
insulation resistance must be higher than 1 Mohm.

Note:
If there is a symmetrically constructed grounding
conductor in the motor cable in addition to the
conductive shield, connect the grounding conductor to
the grounding terminal at the drive and motor ends.
Do not use an asymmetrically constructed motor cable.
Connecting its fourth conductor at the motor end
increases bearing currents and causes extra wear.

Double-shielded cable
Single-shielded cable
Single-shielded cable: Twist the grounding wires of the outer shield and connect
them to the nearest grounding clamp. Double-shielded cable: Connect the inner
shields and the grounding wires of the outer shield to the nearest grounding clamp.
Do not connect shields of different cables to the same grounding clamp.
Leave the other end of the shield unconnected or ground it indirectly via a few
nanofarads high-frequency capacitor (e.g. 3.3 nF / 630 V). The shield can also be
grounded directly at both ends if they are in the same ground line with no significant
voltage drop between the end points.
Keep the signal wire pairs twisted as close to the terminals as possible. Twisting the
wire with its return wire reduces disturbances caused by inductive coupling.

What this Chapter Contains
This chapter shows
• External control connections to the RMIO board for the ACS800 Standard
Application Program (Factory Macro)
• Specifications of the inputs and outputs of the board.
To Which Products this Chapter Applies
This chapter applies to ACS800 units that employ the RMIO board.
Note for the ACS800-U2, ACS800-07/U7, and ACS800-PC
The connections for the RMIO board shown below apply also to optional terminal
block X2 available for the ACS800-02, ACS800-07, and ACS800-PC. The terminals
of the RMIO board are wired to terminal block X2 internally.
Terminals of X2 accept cables from 0.5 to 4.0 mm2 (22 to 12 AWG). Tightening
torque for screw terminals is 0.4 to 0.8 Nm (0.3 to 0.6 lbf ft). For disconnecting wires
from spring terminals, use a screw driver with a blade thickness of 0.6 mm
(0.024 in.) and width of 3.5 mm (0.138 in.), e.g. PHOENIX CONTACT SZF
1-0,6X3,5.
Note on External Power Supply
WARNING! If the RMIO board is supplied from an external power source, the loose
end of the cable removed from the RMIO board terminal must be secured
mechanically to a location where it cannot come into contact with electrical parts. If
the screw terminal plug of the cable is removed, the wire ends must be individually
insulated.

Checking and Replacing the Air Filters
Check the inlet air filters at a minimal interval of every 3 months and replace as need
depending on accumulated dust and the environment. Inlet filters should be changed
at a minimum ever year as part of standard preventative maintenance. The inlet
(door) filter may be accessed and replaced by the following procedure.
1. While holding the top of the filter frame, pull up on the bottom of the frame. The filter
frame will slide up approximately 3/4 inch and can then safely removed by tilting
forward and slightly lifting up.
2. Lay the filter frame on a flat work surface. Remove the 3 retaining brackets by
squeezing the tabbed corners in towards the middle of each bracket until the bracket
clears the filter frame. Save these brackets for replacement. Remove and inspect
the filter.
Maintenance
64
3. Install the replacement filter. Be sure to tuck the filter into the groove around the
entire filter frame. This is very important for proper installation.
Note: When installing the DUSTLOK® filter media, the white side must face the
outside of the cabinet and the orange side must face the inside of the cabinet.
4. Reinstall the 3 filter restraining brackets. These will prevent the filter from being
pulled out of the filter frame. Install the center bracket first and then overlap the
center bracket by ½ to the left for the 2nd bracket and ½ to the right for the 3rd
bracket.

5. Install the filter frame back to the exhaust box on top of the cabinet. Carefully align
the mounting hooks to the slots in the exhaust box. The hooks should be pointing
down. Press down with your hands at the top of the filter frame. The filter frame will
slide down approximately ¾ inch and should be sealed securely to the exhaust box
around the entire filter frame. Repeat this process for the other side.
Installation complete.
Heatsink
Disconnect power before servicing the drive or internal cabinet components.
Check the cleanliness of the cabinet and the surroundings. When necessary, clean
the interior of the cabinet with a soft brush and a vacuum cleaner.
The module heatsink fins pick up dust from the cooling air. The drive runs into
overtemperature warnings and faults if the heatsink is not clean. When necessary,
contact ABB for cleaning of the heatsink (frame sizes R7 and R8).
Fans
The lifespan of the cooling fan of the drive module is about 50,000 hours. The actual
lifespan depends on the running time of the fan, ambient temperature and dust
concentration. See the appropriate ACS800 firmware manual for the actual signal
which indicates the running time of the cooling fan.
Replacement fans are available from ABB. Do not use other than ABB-specified
spare parts.

Capacitors
The drive intermediate circuit employs several electrolytic capacitors. Their lifespan
is at least 90,000 hours depending on the operating time of the drive, loading and
ambient temperature. Capacitor life can be prolonged by lowering the ambient
temperature.
It is not possible to predict a capacitor failure. Capacitor failure is usually followed by
damage to the unit and an input cable fuse failure, or a fault trip. Contact ABB if
capacitor failure is suspected. Replacements are available from ABB. Do not use
other than ABB specified spare parts.

Input Cable Fuses
The drive is equipped for branch circuit protection per NEC with standard T/L fuses
listed below. The fuses restrict drive damage and prevent damage to adjoining
equipment in case of a short-circuit inside the drive. Check that the operating time
of the fuse is below 0.5 seconds. The operating time depends on the fuse type
(class T), supply network impedance and the cross-sectional area, material and
length of the supply cable. The fuses must be of the “non-time delay” type. See also
“Planning the Electrical Installation: Thermal Overload and Short-Circuit
Protection.”
Note 1: In multi-cable installations, install only one fuse per phase (not one fuse per
conductor).
Note 2: Larger fuses must not be used.
Note 3: Fuses from other manufacturers can be used if they meet the ratings and
specifications.

UL/CSA Markings
The ACS800-PC is cUL US listed. The approval is valid with rated voltages (up to
600 V).
UL
The drive is suitable for use on a circuit capable of delivering not more than 65 kA
rms symmetrical amperes at the drive nominal voltage (600 V maximum for 690 V
units).
The drive provides overload protection in accordance with the National Electrical
Code (US). See ACS800 Firmware Manual for setting. Default setting is off; the
setting must be activated at start-up.
The drives are to be used in a heated indoor controlled environment. See section
"Ambient Conditions" for specific limits.
ABB brake choppers, when applied with appropriately sized brake resistors, will
allow the drive to dissipate regenerative energy (normally associated with quickly
decelerating a motor). Proper application of the brake chopper is defined in chapter
"Resistor Braking". This can be applied to a single drive or multiple drives with DC
bus connected to allow a sharing of regenerative energy.
Technical Data
86
Sizing
The current ratings are the same regardless of the supply voltage within one voltage
range. To achieve the rated motor power given in the table, the rated current of the
drive must be higher than or equal to the rated motor current.
Note 1: The maximum allowed motor shaft power is limited to 1.5 · Phd, 1.1 · PN or
Pcont.max (whichever value is greatest). If the limit is exceeded, motor torque and
current are automatically restricted. The function protects the input bridge of the
drive against overload. If the condition exists for 5 minutes, the limit is set to
Pcont.max.
Note 2: The ratings apply at an ambient temperature of 40 °C (104 °F). At lower
temperatures the ratings are higher (except Imax).
Note 3: Use the DriveSize PC tool for a more accurate dimensioning if the ambient
temperature is below 40 °C (104 °F) or the drive is loaded cyclically.
Derating
The load capacity (current and power) decreases if the installation site altitude
exceeds 1000 metres (3281 ft), or if the ambient temperature exceeds 40 °C
(104 °F).
Temperature derating
In the temperature range +40 °C (+104 °F) to +50 °C (+122 °F), the rated output
current is decreased 1 % for every additional 1 °C (1.8 °F). The output current is
calculated by multiplying the current given in the rating table by the derating factor.
Example If the ambient temperature is 50 °C (+122 °F), the derating factor is
100% - 1 % · 10 °C = 90 % or 0.90. The output current is then 0.90 · I2N, 0.90 · I2hd
°C
or 0.90 · Icont.max.
Altitude derating
At altitudes from 1000 to 4000 m (3281 to 13123 ft) above sea level, the derating is
1% for every 100 m (328 ft). For a more accurate derating, use the DriveSize PC
tool. If the installation site is higher than 2000 m (6562 ft) above sea level, please
contact your local ABB distributor or office for further information.

CE Marking
A CE mark is attached to the drive to verify that the unit follows the provisions of the
European Low Voltage and EMC Directives (Directive 73/23/EEC, as amended by
93/68/EEC and Directive 89/336/EEC, as amended by 93/68/EEC).
Definitions
EMC stands for Electromagnetic Compatibility. It is the ability of electrical/electronic
equipment to operate without problems within an electromagnetic environment.
Likewise, the equipment must not disturb or interfere with any other product or
system within its locality.
The EMC Directive defines the requirements for immunity and emissions of electrical
equipment used within the European Union. The EMC product standard [EN 618003 + Amendment A11 (2000)] covers requirements stated for drives.
First environment includes establishments connected to a low-voltage network which
supplies buildings used for domestic purposes.
Second environment includes establishments connected to a network not supplying
domestic premises.
Restricted distribution: mode of sales distribution in which the manufacturer restricts
the supply of equipment to suppliers, customers or users who separately or jointly
have technical competence in the EMC requirements of the application of drives.
Unrestricted distribution: mode of sales distribution in which the supply of equipment
is not dependent on the EMC competence of the customer or user for the application
of drives.
Compliance with the EMC Directive
First Environment
The requirements of the EMC Directive can be met as follows for restricted
distribution:
• The drive is equipped with EMC filter E202.
• The motor and control cables are selected as specified in the Hardware Manual.
• The drive is installed according to the instructions given in the Hardware Manual.
• Maximum cable length is 100 meters.
WARNING! The drive may cause radio interference if used in a residential or
domestic environment. The user is required to take measures to prevent
interference, in addition to the requirements for CE compliance listed above, if
necessary.
Note: It is not allowed to install a drive equipped with EMC filter E202 on IT
(unearthed) systems. The supply network becomes connected to earth potential
through the EMC filter capacitors which may cause danger to personnel or damage
the unit.
Technical Data
92
Second Environment
The requirements of the EMC Directive can be met as follows:

Resistor Braking
What this Chapter Contains
This chapter describes how to select, protect and wire brake choppers and resistors.
The chapter also contains the technical data.
To Which Products this Chapter Applies
This chapter applies to the ACS800-01/U1 (frame sizes R2 to R6), ACS800-02/U2
(frame sizes R7 and R8), ACS800-04/U4 (frame sizes R7 and R8), ACS800-07/U7
(frame sizes R6, R7 and R8), and ACS800-PC.
Availability of Brake Choppers and Resistors for the ACS800
Frame R2 and R3 drives have a built-in brake chopper as standard equipment. For
frames R4 and up, brake choppers are optionally available as built-in units, indicated
in the type code by +D150.
Resistors are available as add-on kits.
How to Select the Correct Drive/Chopper/Resistor Combination
1. Calculate the maximum power (Pmax) generated by the motor during braking.
2. Select a suitable drive / brake chopper / brake resistor combination for the
application according to the following tables (take account of other factors in the
drive selection also).
Note: A resistor other than the standard resistor can be used provided that:
• Its resistance is not lower than the resistance of the standard resistor.
WARNING! Never use a brake resistor with a resistance below the value specified
for the particular drive / brake chopper / resistor combination. The drive and the
chopper are not able to handle the overcurrent caused by the low resistance.

Resistor Installation and Wiring
All resistors must be installed outside the drive module in a place where they will
cool.
WARNING! The materials near the brake resistor must be non-flammable. The
surface temperature of the resistor is high. Air flowing from the resistor is of
hundreds of degrees Celsius. Protect the resistor against contact.
Use the cable type used for drive input cabling (refer to chapter Technical Data) to
ensure the input fuses will also protect the resistor cable. Alternatively, twoconductor shielded cable with the same cross-sectional area can be used. The
maximum length of the resistor cable(s) is 10 m (33 ft). For the connections, see the
power connection diagram of the drive.
Resistor Braking
98
Protection of Frame Sizes R7 and R8 (ACS800-U2, ACS800-U4,
ACS800-PC, ACS800-U7/07)
A main contactor is not required for protecting against resistor overheating when the
resistor is dimensioned according to the instructions and the internal brake chopper
is in use. The drive will disable power flow through the input bridge if the chopper
remains conductive in a fault situation.
Note: If an external brake chopper (outside the drive module) is used, a main
contactor is always required.
A thermal switch (standard in ABB resistors) is required for safety reasons. The
cable must be shielded and not longer than the resistor cable.

With Standard Application Program, wire the thermal switch as shown below. By
default, the drive will stop by coasting when the switch opens.

For other application programs, the thermal switch may be wired to a different digital
input. Programming of the input to trip the drive by “EXTERNAL FAULT” may be
needed. See the appropriate firmware manual.
Brake Circuit Commissioning
For Standard Application Program:
• Enable the brake chopper function (parameter 27.01).
• Switch off the overvoltage control of the drive (parameter 20.05).
• Check the resistance value setting (parameter 27.03).
• Frame sizes R7 and R8: Check the setting of parameter 21.09. If stop by coasting
is required, select OFF2 STOP.
For the use of the brake resistor overload protection (parameters 27.02...27.05),
consult an ABB representative.
WARNING! If the drive is equipped with a brake chopper but the chopper is not
enabled by parameter setting, the brake resistor must be disconnected because the
protection against resistor overheating is then not in use.
For settings of other application programs, see the appropriate firmware manual.
