12 Safety instructions
Safety in installation and maintenance
 Precautions before electrical work
These precautions are for all personnel who do work on the inverter, its input and output
cables, the transformer or photovoltaic generator.
WARNING! Obey these instructions. If you ignore them, injury or death, or
damage to the equipment can occur. If you are not a qualified electrician, do not
do installation or maintenance work. Go through these steps before you begin
any installation or maintenance work.
1. Clearly identify the work location.
2. Disconnect all possible voltage sources.
• Open the AC main switch-disconnector (Q1) and the DC main switch (Q2) of the
inverter.
• Open the disconnector of the transformer as the AC main switch-disconnector
(Q1) does not remove the voltage from the AC busbars of the inverter.
• Open the DC circuit breakers of the solar array junction boxes.
• Make sure that reconnection is not possible. Lock the disconnectors to open
position and attach a warning notice to them.
• After you have disconnected the inverter, always wait for 5 minutes to let the
intermediate circuit capacitors discharge before you continue.
3. Protect any other energized parts in the work location against contact.
4. Take special precautions when close to bare conductors.
5. Measure that the installation is de-energized.
• Use a multimeter with an impedance of at least 1 Mohm.
• Make sure that the voltage between the inverter AC output terminals (L1, L2, L3)
and the grounding (PE) busbar is close to 0 V.
• Make sure that the voltage between the inverter module UDC+ and UDCterminals and the grounding (PE) busbar is close to 0 V.
• Make sure that the voltage between the DC input terminals L+ and L- and the
grounding (PE) busbar is close to 0 V.

14 Safety instructions
 Electrical safety
These warnings are for all personnel who do work on the inverter, its input and output
cables, the transformer or photovoltaic generator.
WARNING! Obey these instructions. If you ignore them, injury or death, or
damage to the equipment can occur.
•
If you are not a qualified electrician, do not do electrical installation or
maintenance work.
•
Never work on the photovoltaic generator or the inverter or its input or output cables
when the inverter is connected to electrical power system or to the photovoltaic
generator. After disconnecting the inverter from the electrical power system and the
DC input, always wait for 5 min to let the intermediate circuit capacitors discharge
before you start working on the inverter, its input and output cables or the photovoltaic
generator.
Always ensure by measuring with a multimeter (impedance at least 1 Mohm) that:
1) Voltage between inverter phases (L1, L2, L3) and the frame is close to 0 V.
2) Voltage between the inverter module terminals (UDC+ and UDC-) and inverter DC
input terminals (L+ and L-) and the frame is close to 0 V.
•
Before working inside the inverter cabinet, isolate the AC line cables and busbars from
the electrical power system with the disconnector of the power system transformer.
Also, isolate the inverter from the photovoltaic generator with the safety switch of the
generator or by other means. The grid disconnecting device (disconnecting means) of
the inverter does not isolate the AC output cables and terminals from the electrical
power system. The DC main switch/switches or DC input circuit breakers do not
isolate the DC input cables or terminals from the DC voltage supplied by the
photovoltaic generator.
•
Before working inside the inverter cabinet, switch off or isolate the auxiliary voltage
supply from the inverter.
•
•
Before working on the unit, apply temporary grounding for work. See page 12.
•
Live parts inside the cubicle are protected against direct contact when all protective
plastic covers and metallic shrouds are in place. Pay special attention when handling
sharp metallic shrouds.
•
Do not make any insulation or voltage withstand tests on the inverter or inverter
modules.
Do not work on the control cables when power is applied to the inverter or to the
external control circuits. Externally supplied control circuits may cause dangerous
voltages inside the inverter even when the main power on the inverter is switched off.
Note:
• The DC connection terminals (UDC+, UDC-, L+ and L-) carry a dangerous DC voltage
(up to 1100 V).
•
External wiring can supply dangerous voltages to the terminals of relay outputs (RO1,
RO2 and RO3).
•
Depending on the external and internal wiring, dangerous voltages (115 V or 230 V)
may be present at different terminals in the auxiliary connection unit.
•
With options +F282 and +F283, one of the poles of the photovoltaic generator is
grounded, and therefore, the other pole has full voltage against ground (up to 1100 V).
Safety instructions 15
•
When the photovoltaic generator cells are exposed to light (even if it is dim), the
generator supplies DC voltage to the inverter.
Grounding
These instructions are for all personnel who are responsible for the grounding of the
inverter.
WARNING! Obey these instructions. If you ignore them, injury or death, or
equipment malfunction can occur, and electromagnetic interference can increase.
•
•
If you are not a qualified electrician, do not do grounding work.
•
Make sure that the conductivity of the grounding conductors is sufficient. See section
Selecting the power cables on page 75. Obey the local regulations.
•
In a multiple-inverter installation, connect each inverter separately to protective earth
(PE) busbar of the switch board or the transformer.
•
When shielded AC power cables are used, make a 360° high frequency grounding of
cable entries at the cabinet lead-through to suppress electromagnetic disturbances. In
addition, connect the cable shields to protective earth (PE) to meet safety regulations.
•
•
•
EMC filters are not allowed at the AC output of the inverter.
Always ground the inverter and adjoining equipment. This is necessary for the
personnel safety. Proper grounding also reduces electromagnetic emission and
interference.
Do not install the inverter on a TN (grounded) system.
Do not install the EMC filter option (+E216) for the network side of the low voltage
transformer on an (ungrounded) system.
Note:
• You can use power cable shields as grounding conductors only when their conductivity
is sufficient.
•
As the normal touch current of the inverter is higher than 3.5 mA AC or 10 mA DC, you
must use a fixed protective earth connection. See standard IEC/EN 62109, 5.2.5.
16 Safety instructions
 General safety
These instructions are for all personnel who install the inverter and do maintenance work
on it.
WARNING! Obey these instructions. If you ignore them, injury or death, or
damage to the equipment can occur.
•
Standard IEC/EN 62109-2 (section 4.8.3.6) requires that as the inverter is not provided
with full protection against shock hazard on the photovoltaic array, you must install and
use the inverter inside a closed electrical operating area.
•
Handle the drive module carefully:
•
•
Use safety shoes with a metal toe cap to avoid foot injury.
•
Lift the module by the upper part only using the lifting hole(s) at the top!
Use extreme caution when manoeuvering an inverter or LCL filter module that
runs on wheels. Extend the support legs of the module when it is removed from
the cabinet! Do not tilt the module! The modules are heavy and have a high center
of gravity. They topple over easily if handled carelessly.
Safety instructions 17
•
When removing a module which is equipped with wheels, pull the module carefully
out of the cubicle along the ramp. Make sure the wires do not catch. While pulling
on the handle, keep a constant pressure with one foot on the base of the module
to prevent the module from tipping over. Use safety shoes with metal toe cap to
avoid foot injury.
•
When replacing a module which is equipped with wheels, push the module up the
ramp into the cubicle. Keep your fingers away from the edge of the module front
plate to avoid pinching them between the module and the cubicle. Also keep a
constant pressure with one foot on the base of the module to stabilize the
movement.
•
Do not use the ramp with plinth heights over 50 mm.The ramp supplied with the
inverter is designed for a plinth height of 50 mm (the standard plinth height of ABB
cabinets). Tighten the four fastening bolts of the ramp carefully.

18 Safety instructions
•
Beware of the cooling fan blades. The fans may continue to rotate for a while after
disconnection of the electrical supply.
•
Beware of hot surfaces. Some parts inside the inverter cabinet, such as heatsinks of
power semiconductors, remain hot for a while after disconnection of the electrical
supply.
•
Make sure that debris from borings and grindings do not enter the inverter during the
installation. Electrically conductive debris inside the unit may cause damage or
malfunction.
•
We do not recommend that you secure the cabinet by arc welding. However, if welding
is necessary, ensure that the return wire is properly connected close to the weld in
order not to damage the electronic equipment in the cabinet. Also ensure that welding
fumes are not inhaled.

Electrical power network supervision functions
The inverter control program includes electrical power network supervision functions. The
inverter monitors, for example, overvoltage, undervoltage, overfrequency, underfrequency
and frequency change rate in the electrical power system. The functions are used for
disconnecting the inverter from the power system in power system fault situations. The
disconnecting times and frequency limits depend on the owner of the power system and
local legislation.
The inverter also provides the electrical power network supervision functions with certified
monitoring relays (options +Q969, +Q974, +Q975 and +Q980).
42 Operation principle and hardware description
Positive or negative pole grounding (options +F282 and
+F283)
The positive and negative pole grounding options can be used when solar modules require
grounding of inverter DC poles. The grounding of the poles complies with standard
IEC 62109-2. One DC line needs to be grounded for certain thin-film photovoltaic module
types and if required by country-specific regulations.
The grounding is always connected when auxiliary power is connected, except when the
automatic photovoltaic generator insulation check is done before the inverter starts.
The grounding wire is protected by a fuse on the PGND-02 board. Due to personnel
protection reasons, the grounding is disconnected when sudden level changes are
monitored from the grounding wire current.
The grounding resistance can be adjusted by the user. For instructions, see page 101.
Reduced run operation in case of a hardware failure
If an inverter module or an LCL filter is out of order, it is possible to continue running the
inverter with reduced output current. In this case the inverter controls only modules which
are unbroken. Inverter output current is reduced in relation to the removed modules. For
example, if one inverter module is broken in PVS800-57-1000kW-C, the inverter output
current is reduced to 66.7% of the nominal current. Reduced run is not possible with
inverters that have only one inverter module.
To operate the PVS800 with reduced run, you must remove the charging circuit fuses
specified in the tables below. However, you do not have to remove the broken inverter
module or LCL filter. This is possible because broken parts can be isolated with AC and
DC contactors inside the PVS800 cabinet. For removing the broken component, obey the
instructions in chapter Maintenance.
Inverter modules are divided into two control groups, which can be enabled or disabled
according to the need. If a module group is disabled, the inverter modules which are part
of that group are not used. The following tables list the possible control combinations in the
reduced run operation.

The modules run on wheels, which, along with the quick connector at the AC output,
enable quick replacement of a module for maintenance.
The inverter module is equipped with a speed-controlled cooling fan involving a power
supply board and a fan inverter board that outputs a frequency in the range of 15 to 55 Hz
to the fan. The fan is regulated according to the temperature of the output stage of the
module. The power to the fan is supplied from the intermediate DC circuit.

Mechanical installation
Contents of this chapter
This chapter describes the mechanical installation procedure of the inverter.
Checking the installation site
See section Ambient conditions on page 144 for allowable operating conditions, and
section Dimensions, weights and free space requirements on page 132 for requirements
for free space around the unit.
The floor that the unit is installed on must be of non-flammable material, as smooth as
possible, and strong enough to support the weight of the unit. The floor flatness must be
checked with a spirit level before the installation of the cabinets into their final position. The
maximum allowed deviation from the surface level is 5 mm in every 3 metres. The
installation site should be levelled, if necessary, as the cabinet is not equipped with
adjustable feet.
64 Mechanical installation
Note: For easy maintenance, do not install the inverter on a higher level than the floor in
front of it. If the inverter is placed higher, the ramp supplied with the inverter cannot be
used when replacing an inverter module.
The wall behind the unit must be of non-flammable material.
Required tools
The tools required for moving the unit to its final position, fastening it to the floor and
tightening the connections are listed below:
• crane, fork-lift or pallet truck (check load capacity!); iron bar, jack and rollers
•
•
•
Pozidrive and Torx (2.5–6 mm) screwdrivers for the tightening of the frame screws
torque wrench
set of wrenches and sockets.
Checking the delivery
The inverter delivery contains:
• inverter cabinet line-up
•
•
•
•
optional modules (if ordered) installed onto the RDCU control units

Miscellaneous
 Preventing the recirculation of hot air
Prevent hot air circulation outside the inverter by leading the outcoming hot air away from
the area where the inlet air to the inverter is taken. Also, ensure that the hot air from the
inverter module cubicle cannot enter the adjacent cubicles.
 Ventilation duct at the air outlet of the cabinet
A ventilation duct can be constructed at the air outlet of the inverter cabinet. If an exhaust
fan is used, ensure that the capacity is sufficient. See Losses, cooling data and noise on
page 133.
Note: The ventilation system must keep the static pressure in the air outlet duct sufficiently
below the pressure of the room where the inverter is located in order that the cabinet fans
can produce the required air flow through the cabinet. Ensure that no dirty or moist air is
able to flow backward to the inverter in any case, even during off-time or while servicing
the inverter or the ventilation system.
70 Mechanical installation
Calculating the required static pressure difference
The required static pressure difference between the exit air duct and the inverter
installation room can be calculated as follows:
ps = (1.5…2) • pd
ǻ
where
pd = 0.5 • • vm2
vm = q / Ac
dynamic pressure
pd
air density (kg/m3)
vm
average air velocity in the exit duct(s) (m/s)
q
rated air flow of the inverter (m3/s)
Ac
cross-sectional area of the exit duct(s) (m2)
Example:
The cabinet has 3 exit openings of 315 mm diameter. The rated air flow of the cabinet is
3760 m3/h = 1.0 m3/s.
Ac = 3 • 0.3152 • / 4 = 0.234 m2
vm = q / Ac = 1.0 / 0.234 = 4.3 m/s
pd = 0.5 • • vm2 = 0.5 • 1.1 • 4.32= 10 Pa
The required pressure in the exit air duct is then, 1.5…2 • 10 Pa = 15…20 Pa, below the
pressure in the room.
More information: Contact ABB.
Mechanical installation 71
 Cable duct in the floor below the cabinet
A cable duct can be constructed below the middle part of the cabinet. The duct width may
not exceed 450 mm. The cabinet weight lies on the 100 mm wide section in front and
50 mm wide section on the back which the floor must carry.
Prevent the cooling air flow from the cable duct to the cabinet by bottom plates. To ensure
the degree of protection for the cabinet, use the original bottom plates delivered with the
unit. With user-defined cable entries, take care of the degree of protection, fire protection
and EMC compliance.

Contents of this chapter
This chapter contains the instructions that you must obey when selecting the cables,
transformer, protections, cable routing and way of operation for the inverter system.
Limitation of liability
The installation must always be designed and made according to applicable local laws and
regulations. ABB does not assume any liability whatsoever for any installation which
breaches the local laws and/or other regulations. Furthermore, if the recommendations
given by ABB are not followed, the inverter may experience problems that the warranty
does not cover.
Selecting the transformer
Transformers designed for photovoltaic applications are available from ABB. Each inverter
must be galvanically isolated from other inverters and medium and low voltage network by
a dedicated transformer or winding. If you intend to connect inverters in parallel, please
contact ABB for more information. ABB recommends a transformer designed for the
environment where it will be installed, compliance with power transformer standard IEC
60076 and testing according to converter transformer standard for industrial applications
IEC 61378-1. Country-specific requirements must always be fulfilled.
74 Planning the electrical installation
 Requirements for the transformer
•
•
•
suitable for the network and inverter AC voltage, current and power
•
•
equipped with a static grounded screen between the high and low voltage windings
suitable for use with IGBT inverters
degree of protection, temperature limits and lifetime are appropriate for the
environment
voltage withstand level of the low voltage winding is at least 1.6 kV against ground. A
typical voltage waveform against ground is shown below.
UAC-grid (V)
t (ms)
•
voltage rise time withstand level (du/dt) of the low voltage winding is at least 1000 V
per microsecond against ground.
•
recommended rated short-circuit impedance (Xk) for each inverter is approximately
6% (±1%)
•
withstands low-voltage side current DC components of at least 0.5% of the nominal
rated current preferably without using an air gap
•
withstands the 3% total harmonic distortion generated by the inverter. However, we
recommend dimensioning the transformer for at least 5% total harmonic distortion to
withstand possible outside interference from the network.
ABB recommends that the transformer is equipped with an off-load tap changer for voltage
regulation on the high-voltage side of the winding with two 2.5% step points to the plus and
minus directions.
The inverter does not require any specific transformer notation. ABB recommends using
traditional notations, such as Dy11d0, Dy11y11, etc.
Do not ground the neutral (star) point of the transformer or connect it to the neutral points
of other windings.
Planning the electrical installation 75
Selecting the grid disconnecting device
The inverter is equipped with a hand-operated disconnecting device which isolates the
inverter and the solar generator from the electrical power system. The disconnecting
device does not, however, isolate the inverter AC output busbars from the power system.
Therefore, during installation and maintenance work on the inverter, the AC output cables
and busbars must be isolated from the electrical power system with a disconnector at the
transformer.
Selecting the DC input disconnecting device
As standard, the inverter is equipped with a hand-operated disconnecting device.
Optionally, PVS800-57-0100kW can be equipped with miniature DC input circuit breakers
(option +H377). The breakers do not, however, isolate the inverter DC input conductors
and terminals from the input voltage. Therefore, the junction boxes must be equipped with
breakers for the isolation.
Checking the compatibility of the solar generator and
inverter
Check that
• generator current and voltage match the rated values of the inverter
•
generator open circuit voltage does not exceed the maximum allowed DC voltage of
the inverter
•
generator operating range lies between the limits of the maximum power point tracking
(MPPT) function of the inverter control program
•
generator grounding requirements match with the inverter.
Selecting the power cables
 General rules
Dimension the DC input power and AC output power cables according to local
regulations:
• Dimension the cable to carry the inverter load current. See chapter Technical data for
the rated currents.
•
Select a cable rated for at least 70 °C maximum permissible temperature of conductor
in continuous use.
•
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).
•
Select an AC output cable rated for at least 0.6/1.0 kV AC.
A two-conductor system is allowed for the DC input cabling but a shielded cable can also
be used.
Shield
76 Planning the electrical installation
Symmetrical shielded cable is recommended for the AC output cabling; see section
Recommended AC output power cable types below. Compared to a four-conductor
system, the use of symmetrical shielded cable reduces electromagnetic emission of the
whole inverter system.
Note: When continuous metal conduit is employed, shielded cable is not required. The
conduit must have bonding at both ends as with cable shield.
To operate as a protective conductor, the shield conductivity requirements according to
IEC 61439-1 are shown below when the protective conductor is made of the same metal
as the phase conductors:
Cross-sectional area of
the phase conductors

S < 16
16 < S < 35
35 < S
Minimum cross-sectional
area of the corresponding

S/2
To effectively suppress radiated and conducted radio-frequency emissions, the cable
shield conductivity must be at least 1/10 of the phase conductor conductivity. The
requirements are easily met with a copper or aluminum shield. The minimum requirement
of the cable shield is shown below. It consists of a concentric layer of copper wires with an
open helix of copper tape or copper wire. The better and tighter the shield, the lower the
emission level.

WARNING! Ground all conductive cable supports, cable clamps and
individual conductive items close to cables, such as cable trays. A
dangerous voltage can become present on the non conductive outer
sheath of the cable. This can cause injury or death.
 Not allowed power cable types
PE
Symmetrical shielded cable with individual shields for each phase conductor is not
allowed on any power cabling.
Selecting the control cables
 General rules
All control cables must be shielded.
Use a double-shielded twisted pair cable for analog signals. Employ one individually
shielded pair for each signal. Do not use common return for different analog signals.
A double-shielded cable is the best alternative for low-voltage digital signals but singleshielded twisted pair cable (Figure b) is also usable.

78 Planning the electrical installation
Signals in separate cables
Run analog and digital signals in separate, shielded cables.
Never mix 24 V DC and 115/230 V AC signals in the same cable.
Signals allowed to be run in the same cable
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.
Relay cable type
The cable type with braided metallic screen (eg, ÖLFLEX by LAPPKABEL, Germany) has
been tested and approved by ABB.
Installation sites above 2000 metres (6560 feet)
WARNING! Protect against direct contact when installing, operating and servicing
the RMIO board wiring and optional modules attached to the board. The
Protective Extra Low Voltage (PELV) requirements stated in EN 50178 are not
fulfilled at altitudes above 2000 m (6560 ft).
Routing the cables
It is recommended that the input DC power cable, output AC power cable and control
cables be installed on separate trays.
Where control cables must cross power cables ensure they are arranged at an angle as
near to 90 degrees as possible. Do not run extra cables through the inverter.
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.
If four conductor AC cabling is used, place the three output phase cables symmetrically
and close to each other. Asymmetrical installation may induce current to grounding cables
and metal structures.
A diagram of the cable routing is shown below.

24 V (120 V)
Not allowed unless the 24 V cable is
insulated for 230 V (120 V) or insulated
with an insulation sleeving for 230 V
(120 V).
Implementing short-circuit and thermal overload
protection
 Protecting the inverter and AC output cable in short-circuit
situations
The inverter is equipped with internal AC fuses which restrict inverter damage in case of a
short-circuit inside the inverter. Install external protection (such as fuses) according to local
regulations, appropriate AC line voltage and the rated current of the inverter to protect the
AC output cable.
 Protecting the photovoltaic generator and DC input cable in short-
circuit situations
The input DC fuses or optional DC input miniature circuit breakers (option +H377) protect
the inverter DC circuit and the DC input cables in a short-circuit situation when the cable is
dimensioned according to inverter nominal DC current and fuse and breaker ratings. See
section Fuses on page 127 for the fuse and breaker ratings.
To protect inverters delivered without input DC fuses (option +0F291), follow the
instructions in section Instructions for inverters delivered without input DC fuses (option
+0F291) on page 82.
Note: The inverter does not protect the photovoltaic generator. Install adequate protection
devices to, for example, each string.
 Protecting the inverter and the AC output cable against thermal
overload
The inverter protects itself and the AC output cable against thermal overload when the
cable is dimensioned according to the nominal current of the inverter. No additional
thermal protection devices are needed.
80 Planning the electrical installation
Supplying power for the auxiliary circuits
Supply the inverter with rated auxiliary voltage. Protect the supply according to local
regulations with, eg, fuses and/or fault current breakers. Do not connect any additional
appliances to the inverter without consulting with ABB.
Implementing the low voltage ride-through function
The user can define by parameters when the inverter must stay connected to the grid (ie,
the depth and length of the grid voltage transient). The user can also define how much the
inverter supports the grid with capacitive reactive current during the grid voltage transient.
For more information, see PVS800 central inverters firmware manual (3AUA0000058422
[English]).
If a low voltage ride-through function is used with the PVS800-57-100kW-A, PVS800-57250kW-A or PVS800-57-315kW-B inverters, the auxiliary power supply must be
uninterruptible (that is, the auxiliary voltage is not allowed to have voltage dips). Use of an
external UPS device (uninterruptible power supply) is recommended in that case.
Supplying circuits from the AC output of the inverter
If the AC output of the inverter is used for supplying any circuits, provide galvanic isolation
as shown in the diagram below. A denotes other equipment and B supplying auxiliary
circuit of the inverter. See also Connecting the external power supply cable for the
auxiliary circuit on page 89. For instructions on selecting the transformer, see section
Selecting the transformer on page 73.

Planning the electrical installation 81
Implementing ground fault monitoring in IT (ungrounded)
systems
The internal ground fault monitoring of the inverter is based on total sum of the phase
current measurements. The monitoring will detect severe ground faults in IT (ungrounded)
systems. However, often the ground fault leakage current does not exceed the trip level
and the inverter remains is operation. The inverter can be equipped with insulation
monitoring device option +Q954, +Q976 or +Q981, or the IT system must be monitored
otherwise with a monitoring device suitable for use with inverters. Because of the leakage
currents of inverters, many ground fault monitoring devices do not work properly with
them.
 Insulation monitoring device (options +Q954, +Q976 and +Q981)
Options +Q954, +Q976 and +Q981 include an insulation monitoring device with a coupling
device that enables measurement of the insulation resistance. According to the IEC
62109-2 standard, the measurement is needed before the inverter can be started.
The insulation monitoring device measures insulation resistance between the DC busbars
and protective earth (PE). When the inverter is operating, the insulation resistance of the
AC busbars against the protective earth is also measured indirectly. The monitoring device
reacts to all ground faults in IT systems which are galvanically connected to each other.
If the insulation resistance between the conductors and the ground falls below the set
response values, the state of the alarm relay in the insulation monitoring device is
changed, and in R7i and R8i the indication LED on the cabinet door lights up. The inverter
is tripped or an alarm is generated depending on the parameter settings. The measured
insulation resistance value can be read from the inverter parameters in 3 × R8i frames
equipped with option +Q954.
When auxiliary power to the insulation monitoring device is switched off, its alarm relays
are switched to the fault position.
With option +Q954, the response values and parameters of the insulation monitoring
device can be set with its function keys.
Note: The insulation monitoring device measures the insulation resistance of the solar
generator correctly according to the settings when the inverter is not operating. For
disabling the monitoring device during the inverter operation, contact ABB.
Safety information
The insulation monitoring device is constructed according to state-of-the-art and
recognized technical safety rules. Nevertheless, when the device is used, hazards may
occur to the life and limb of the user or of third parties, or there may be adverse effects on
the monitoring device or on other valuable property. The monitoring device must only be
used
• for the purpose for which it is intended
•
when it is in perfect technical condition as far as safety is concerned.
Only one insulation monitoring device may be used in each interconnected IT system.
When insulation or voltage test is to be carried out, the device is to be isolated from the
system for the test period.
The ground fault monitoring function (+Q954, +Q976 and +Q981) is not a personnel safety
or fire protection feature.

Implementing positive or negative pole grounding
(options +F282 and +F283)
Some solar module types require positive or negative grounding. Make sure that the
optional positive (+F282) or negative (+F283) grounding method is suitable for the solar
modules that you are using.
Ground the panels during long maintenance breaks if the panel type requires it.
Limiting the conducted disturbances with the EMC filter
(option +E216) in low-voltage TN (grounded) networks
The optional EMC filter (+E216) can be installed at the network-side of the low voltage
transformer to limit the conducted disturbances to other equipment connected to the
network. The filter has capacitors connected to ground and is not suitable for IT
(ungrounded) networks. Ensure that the network owner and operator allows the
installation of this kind of a filter. The filter must always be installed according to local
regulations.
Instructions for inverters delivered without input DC
fuses (option +0F291)
If the standard input DC fuses are not suitable for the customer application, the inverter
can be delivered without input DC fuses (option +0F291). In this case, install appropriate
DC fuses to protect the inverter DC circuit and the DC input cables in a short-circuit
situation. Protect the positive and negative poles of an input with separate fuses. The
power loss of a fuse may never exceed 25 W.
The table in section Fuses for inverters delivered without input DC fuses (option +0F291)
(page 130) shows the rated DC current for selecting the input DC fuses.
 Mechanical installation of the input DC fuses
Use M10 or M12 bolts and nuts to connect the fuses to the busbars.

during the insulation check.
Checking the compatibility with IT (ungrounded) systems
The EMC filter (option +E216) is not suitable for use in an IT (ungrounded) system. Check
that the low-voltage network is of the TN (grounded) type. If not, please contact ABB.
WARNING! If the optional EMC filter +E216 is installed on an IT system (an
ungrounded power system or a high resistance-grounded [over 30 ohm] power
system, the system will be connected to earth potential through the EMC filter
capacitors. This may cause danger or damage the equipment in the network.

Note: If the outer surface of the shield is non-conductive:
• Cut the shield at the midpoint of the bare part. Be careful not to cut the conductors or
the grounding wire (if present).
•
•
Turn the shield inside out to expose its conductive surface.

Connecting the cables to the I/O terminals
Connect the conductors to the appropriate detachable terminals of the RMIO board (see
pages 92 and 93). At the terminal block, use shrink tubing or insulating tape to contain any
stray strands. The shield (especially in case of multiple shields) can also be terminated
with a lug and fastened with a screw at nearest grounding clamp. Leave the other end of
the shield unconnected or ground it indirectly via a few nanofarads high-frequency
capacitor, eg, 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.Tighten the screws to secure the connection.
Note: Keep any signal wire pairs twisted as close to the terminals as possible. Twisting the
wire with its return wire reduces disturbances caused by inductive coupling.
Connecting a PC
For connecting a PC to the inverter during the start-up procedure, see chapter Start-up.
For normal use, connect the PC through a fiber optic link to CH3 of the RDCO module
inserted in the master control unit (A43).
Installing optional modules
 Mechanical installation
Optional modules such as fieldbus adapters and I/O extensions are inserted in the optional
module slot on the RDCU control unit at the factory. The module is fastened with a screw.
See page 52 for the available slots.
Note: Correct installation of the screw is essential for fulfilling the EMC requirements and
for proper operation of the module.
 Wiring the modules
See the appropriate optional module manual for specific installation and wiring
instructions.

Start-up
Contents of this chapter
This chapter describes the start-up procedure of the inverter. It also gives some advice for
operation.
Start-up procedure
The functioning of the inverter is first tested in the local control mode with the control panel
(CDP312R). Thereafter, the control program parameters are set. The start-up procedure is
described step-by-step in the table below.
SAFETY
WARNING! Obey the safety instructions during the
installation and start-up procedure. See chapter Safety
instructions.
Only qualified electricians are allowed to install and start-up the
inverter.
PRIMARY AND AMBIENT CONDITION CHECKS
Check that the mechanical and electrical installation of the
inverter is OK. See chapter Installation checklist.
Check that the insulation of the assembly is OK. See section
Checking the insulation of the assembly, page 83.
Check that the ambient conditions for start-up, temperature and
humidity level is within the limits. See section Ambient conditions,
page 144.
Note: Depending on the humidity level or temperature, it can be
necessary to use cabinet heaters continuously for a longer time
before start-up.
Note: If the insulation is not OK, the
optional insulation resistance
monitoring (option +Q954, +Q976 or
+Q981) cannot be tuned properly.
100 Start-up
Set up the cabinet heater (option +G300):
• Set the maximum temperature with the T65 thermostat (default
10 °C).
Note: Especially in very humid conditions when the inverter is
installed on the site for a longer period without grid connection
keep the cabinet heaters on for several days before
commissioning.
Choose the control mode by connecting the heater power supply
wire to one of the three terminals listed below:
• X5:3 = Heating is switched off by the T65 thermostat and when
the inverter is modulating.
• X5:4 = Heating is controlled by the K65 customer control relay
24 V DC control signal and by the T65 thermostat.
• X5:5 = Heating is only controlled by the T65 thermostat.
The optional cabinet heater has
three control modes (see circuit
diagram sheets 64 and 65 delivered
with the inverter). The control mode
can be selected by changing the
heater power supply wire in the
auxiliary control cabinet.
More information:
Circuit diagrams delivered with the
inverter
Check that it is light enough for the inverter to be able to feed
power to the AC power system (grid) once it is operating.
Note: There must be enough light so
that the solar generator is able to
feed power to the inverter. This
enables verifying that the inverter
functions properly. Parameter
settings can be done during the dark
hours. Also, the inverter modulation
can be tested without input power
from the photovoltaic arrays.
Check that the polarity and voltage of each connected DC solar
string is correct:
Note: There should be a
record/document stating that the
polarity and voltage of each solar
string is correct.
• Remove the inverter DC fuses.
• Measure that the plus pole is connected to the plus terminal
and the minus pole to the minus terminal and the voltage is
correct.
• Put the DC fuses back into their place.
Verify the expected DC voltage. Check that the open circuit DC
voltage from the solar generator lies within the allowed range of
the inverter (eg, 450…1000 V DC).
Note: The expected DC voltage can
be estimated by using the open
circuit voltage of the solar modules
and the number of modules in a
string.
SETTING UP THE INSULATION MONITORING DEVICE (options +Q954, +Q976
and +Q981)
Check that there is only one insulation monitoring device for the
inverter in the same galvanically connected IT system.
Note: Using more than one
insulation monitoring device in the
galvanically connected IT system will
cause false results in the insulation
measurement.
Check that the settings of the insulation monitoring device suit
the installation and agree with the local regulations. The trip limit
is adjusted to 30 kohm at the factory by default.

112 Maintenance
Fans
The cooling fan lifespan depends on the inverter usage and ambient temperature. See the
firmware manual for an actual signal which indicates the hours of usage of the fan.
Fan failure can be predicted by the increasing noise from fan bearings and the gradual rise
in the heatsink temperature in spite of heatsink cleaning. If the inverter is operated in a
critical part of a process, fan replacement is recommended once these symptoms start
appearing. Replacement fans are available from ABB. Do not use other than ABBspecified spare parts.

Replacing the LCL filter
Contact ABB.
Maintenance 121
Capacitors
The inverter intermediate circuit employs several electrolytic capacitors. Their lifespan
depends on the inverter loading and ambient temperature. Capacitor life can be prolonged
by lowering the ambient temperature. Capacitor life shortens in high ambient temperatures
and under heavy loading.
It is not possible to predict a capacitor failure. Capacitor failure is usually followed by a
mains 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.
 Reforming the capacitors
Reform (re-age) spare part capacitors once a year according to Capacitor reforming
instructions (3BFE64059629 [English]).

Nominal ambient temperature
 With temperature compensated altitude derating
Each degree of maximum ambient temperature below the nominal ambient temperature
gives a compensation to the altitude derating, but the temperature derating curve and
maximum allowed altitude must not be exceeded. When calculating the compensated
altitude derating factor, you must observe the corner points of the temperature rating
curves.
Example1: For inverter types PVS800-57-0100kW-A and PVS800-57-0250kW-A installed
at 1800 m (5900 ft), if the maximum ambient temperature is limited to +35 °C (95 °F), the
compensated altitude derating factor is 100% - 8 · 1% + (40 - 35) · 1% = 97% or 0.97.
Example 2: For inverter types PVS800-57-0315kW-B, PVS800-57-0630kW-B installed at
2100 m (6890 ft), if the maximum ambient temperature is limited to +35 °C (95 °F), the
compensated altitude derating factor is 100% - 11 · 1% + (45 - 35) · 0.5% = 94% or 0.94.
Example 3: For inverter types PVS800-57-0500kW-A, PVS800-57-0875kW-B and
PVS800-57-1000kW-C installed at 2800 m (9200 ft), if the maximum ambient temperature
is limited to +32 °C (89 °F), the compensated altitude derating factor is 100% 18 · 1% + (50 - 45) · 1.6% + (45 - 32) · 0.6% = 97.8% or 0.978.

Type -1000kW-C : 400 V AC 3-phase ± 10%
3-phase IT (ungrounded) system. Galvanic isolation for each inverter is
needed.
The transformer must be suitable for IGBT-based inverter use with high du/dt
values against the ground. Dedicated low-voltage winding is needed for each
inverter. Static screen between windings with proper dimensioning is
needed.
For details on selecting the transformer, see Selecting the transformer on
page 73.
Type -0100kW-A: Maximum allowable prospective short-circuit current is
10 kA when protected by fuses given in fuse tables.
Types -0250kW-A … -1000kW-C: Maximum allowable prospective shortcircuit current is 50 kA when protected by fuses given in fuse tables.

Fundamental power factor
(cos phi1)
When temporary grounding for work is applied (the grounding cables are
connected to the connecting knobs of the AC and DC busbars and PE of the
inverter): the maximum allowable prospective short-circuit current is
decreased to 25 kA / 1 s. If the connected grounding cables and clamps are
not equivalent to the prospective short-circuit rating of the inverter, the total
rating will be lower.
48 to 63 Hz withstand with normal dimensioning (grid-compliance may
require disconnection at smaller values.) Maximum rate of change 17%/s
Max. ± 3% of nominal phase to phase AC line voltage
Max. 25%
Note: If the inverter is expected to survive voltage dips (low-voltage ridethrough), auxiliary power supply must be ensured, for example, by an
uninterruptible power supply.
