•
The VLT® AQUA Drive FC 202 Operating Instructions
provide details on installation and operation of
the frequency converter.
•
The VLT® AQUA Drive FC 202 Programming Guide
provides greater detail on working with
parameters and many application examples.
•
The VLT® AQUA Drive FC 202 Design Guide
provides detailed capabilities and functionality to
design motor control systems.
•
Supplemental publications and manuals are
available from Danfoss.
See www.danfoss.com/BusinessAreas/DrivesSolutions/Documentations/Technical
+Documentation.htm for listings.
•
Optional equipment may change some of the
procedures described. Reference the instructions
supplied with those options for specific
requirements. Contact the local Danfoss supplier
or visit the Danfoss website: www.danfoss.com/
BusinessAreas/DrivesSolutions/Documentations/
Technical+Documentation.htm, for downloads or
additional information.
•
The VLT® Active Filter AAF00x Operating
Instructions provide additional information about
the filter portion of the Low Harmonic Drive.
A frequency converter (also called a drive) is an electronic
motor controller that converts DC into a variable AC
waveform output. The frequency and voltage of the output
are regulated to control the motor speed or torque. The
frequency converter can vary the speed of the motor in
response to system feedback, such as with position sensors
on a conveyor belt. The frequency converter can also
regulate the motor by responding to remote commands
from external controllers.
The frequency converter

monitors the system and motor status
issues warnings or alarms for fault conditions
starts and stops the motor
optimises energy efficiency
Operation and monitoring functions are available as status
indications to an outside control system or serial communication network.
A Low Harmonic Drive (LHD) is a single unit that combines
the frequency converter with an advanced active filter
(AAF) for harmonic mitigation. The frequency converter
and filter are 2 separate pieces packaged together in an
integrated system, but each functions independently. In
this manual, there are separate specifications for the
frequency converter and the filter. Since the frequency
converter and filter are together in the same enclosure, the
unit is transported, installed, and operated as a single
entity.

1.3.2 Working Principle
The VLT Low Harmonic Drive is a high-power frequency converter with an integrated active filter. An active filter is a device
that actively monitors harmonic distortion levels and injects compensative harmonic current onto the line to cancel the
harmonics.

Illustration 1.1 Basic Layout for the Low Harmonic Drive
Low Harmonic Drives are designed to draw an ideal sinusoidal current waveform from the supply grid with a power factor
of 1. Where traditional non-linear load draws pulse-shaped currents, the Low Harmonic Drive compensates that via the
parallel filter path, lowering the stress on the supply grid. The Low Harmonic Drive meets the highest harmonic standards
with a THiD less than 5% at full load for <3% pre-distortion on a 3% unbalanced 3-phase grid.

The following symbols are used in this document:
WARNING
HIGH VOLTAGE
WARNING
Indicates a potentially hazardous situation which could
result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation which could
result in minor or moderate injury. It may also be used
to alert against unsafe practices.
Frequency converters contain high voltage when
connected to AC mains input power. Qualified personnel
only should perform installation, start up, and
maintenance. Failure to perform installation, start up,
and maintenance by qualified personnel could result in
death or serious injury.
WARNING
UNINTENDED START
NOTICE
Indicates important information, including situations that
may result in damage to equipment or property.
2.2 Qualified Personnel
Correct and reliable transport, storage, installation,
operation and maintenance are required for the safe
operation of the frequency converter. Only qualified
personnel are allowed to install or operate this equipment.
Qualified personnel is defined as trained staff, who are
authorised to install, commission, and maintain equipment,
systems and circuits in accordance with pertinent laws and
regulations. Additionally, qualified personnel are familiar
with the instructions and safety measures described in this
document.
When the frequency converter is connected to AC mains,
the motor may start at any time. The frequency
converter, motor, and any driven equipment must be in
operational readiness. Failure to be in operational
readiness when the frequency converter is connected to
AC mains could result in death, serious injury,
equipment, or property damage.
WARNING
DISCHARGE TIME
Frequency converters contain DC-link capacitors that can
remain charged even when the frequency converter is
not powered. To avoid electrical hazards, disconnect AC
mains, any permanent magnet type motors, and any
remote DC-link power supplies, including battery backups, UPS, and DC-link connections to other frequency
converters. Wait for the capacitors to fully discharge
before performing any service or repair work. The
amount of wait time is listed in the Discharge Time table.
Failure to wait the specified time after power has been
removed before doing service or repair could result in
death or serious injury.

•
Compare the model number on the nameplate to
what was ordered to verify the proper equipment
•
Ensure each of the following are rated for the
same voltage:
•
-
Mains (power)
-
Frequency converter
-
Motor
Ensure the output current rating is equal to or
greater than the motor full load current for peak
motor performance.
-
-
Motor size and frequency converter
power must match for proper overload
protection.
If frequency converter rating is less than
that of the motor, full motor output is
impossible.

3.4.1 Cooling and Airflow
Back cooling
The backchannel air can also be ventilated in and out the
back of a Rittal TS8 enclosure for frame size F18 LHD. This
offers a solution where the backchannel could take air
from outside the facility and return the heat loses outside
the facility thus reducing air-conditioning requirements.
NOTICE
A door fan(s) is required on the enclosure to remove the
heat losses not contained in the backchannel of the
drive and any additional losses generated from other
components installed inside the enclosure. The total
required air flow must be calculated so that the
appropriate fans can be selected. Some enclosure
manufacturers offer software for performing the
calculations (i.e. Rittal Therm software).
Airflow
The necessary airflow over the heat sink must be secured.
The flow rate is shown in Table 3.1.
Cooling
Cooling can be obtained in different ways, by using the
cooling ducts in the bottom and the top of the unit, by
taking air in and out the back of the unit or by combining
the cooling possibilities.

See chapter 2 Safety for general safety instructions.
To obtain an EMC-compliant installation, follow the
instructions provided in chapter 4.4 Grounding,
chapter 4.5 Input Options, chapter 4.6 Motor Connection, and
chapter 4.8 Control Wiring.
WARNING
INDUCED VOLTAGE
Induced voltage from output motor cables that run
together can charge equipment capacitors even with the
equipment turned off and locked out. Failure to run
output motor cables separately or use screened cables
could result in death or serious injury.
•
•
Run output motor cables separately, or
use screened cables
CAUTION
SHOCK HAZARD
The frequency converter can cause a DC current in the
PE conductor. Failure to follow the recommendation
below means the RCD may not provide the intended
protection.
•
When a residual current-operated protective
device (RCD) is used for protection against
electrical shock, only an RCD of Type B is
permitted on the supply side.
Overcurrent Protection
•
•
Additional protective equipment such as short
circuit protection or motor thermal protection
between frequency converter and motor is
required for applications with multiple motors.
Input fusing is required to provide short circuit
and overcurrent protection. If not factorysupplied, fuses must be provided by the installer.
See maximum fuse ratings in chapter 8.5 Fuses.

NOTICE
Cables–General Information
All cabling must comply with national and local
regulations on cable cross-sections and ambient
temperature. UL applications require 75 °C copper
conductors. For non-UL applications, 75 and 90 °C
copper conductors are thermally acceptable.
The power cable connections are situated as shown in
Illustration 4.1. Dimension cable cross-section in accordance
with the current ratings and local legislation. See
chapter 8.3.1 Cable lengths and cross-sections for details.
For protection of the frequency converter, use the
recommended fuses if there are no built-in fuses. Fuse
recommendations are provided in chapter 8.5 Fuses. Ensure
that proper fusing is made according to local regulation.
The mains connection is fitted to the mains switch, if

Electrical Installation
Operating Instructions
Screening of cables
Avoid installation with twisted screen ends (pigtails). They
spoil the screening effect at higher frequencies. If breaking
the screen is necessary to install a motor isolator or
contactor, continue the screen at the lowest possible HF
impedance.
Connect the motor cable screen to both the de-coupling
plate of the frequency converter and to the metal housing
of the motor.
Make the screen connections with the largest possible
surface area (cable clamp). Use the installation devices
within the frequency converter.
Cable-length and cross-section
The frequency converter has been EMC tested with a given
length of cable. Keep the motor cable as short as possible
to reduce the noise level and leakage currents.
Switching frequency
When frequency converters are used together with sinewave filters to reduce the acoustic noise from a motor, the
switching frequency must be set according to
14-01 Switching Frequency.

4.4 Grounding
Consider the following basic issues for electromagnetic
compatibility (EMC) during installation:
• Safety grounding: The frequency converter has a
high leakage current and must be grounded
appropriately for safety reasons. Apply local
safety regulations.
•
High-frequency grounding: Keep the ground wire
connections as short as possible.
Connect the different ground systems at the lowest
possible conductor impedance. Keep the conductor as
short as possible and use the greatest possible surface area
for the lowest possible conductor impedance.
The metal cabinets of the different devices are mounted
on the cabinet rear plate using the lowest possible HF
impedance. Doing so avoids different HF voltages for
individual devices and the risk of radio interference
currents running in connection cables between the
devices. The radio interference is reduced.
To obtain a low HF impedance, use the fastening bolts of
the devices as HF connection to the rear plate. Remove
insulating paint or similar from the fastening points.

Mains supply isolated from ground
If the frequency converter is supplied from an isolated
mains source or TT/TN-S mains with grounded leg, turn off
the RFI switch via 14-50 RFI Filter on both frequency
converter and the filter. For further reference, see IEC
364-3. When optimum EMC performance is needed,
parallel motors are connected, or the motor cable length is
above 25 m, set 14-50 RFI Filter to [ON].
In OFF, the internal RFI capacitors (filter capacitors)
between the chassis and the intermediate circuit are cut
off to avoid damage to the intermediate circuit and reduce
ground capacity currents (IEC 61800-3).
Refer to the application note VLT on IT mains. It is
important to use isolation monitors that work together
with power electronics (IEC 61557-8).

For motor cable lengths ≤ the maximum cable length, the
motor insulation ratings listed in Table 4.5 are
recommended. The peak voltage can be twice the DC-link
voltage or 2.8 times mains voltage, due to transmission
line effects in the motor cable. If a motor has lower
insulation rating, use a dU/dt or sine wave filter.

Although failure due to bearing currents is infrequent, use
the following strategies to reduce the likelihood:
•
•
•
Use an insulated bearing
Apply rigorous installation procedures
Ensure that the motor and load motor are
aligned
•
•
Strictly follow the EMC Installation guideline
•
Provide a good high frequency connection
between the motor and the frequency converter
•
Ensure that the impedance from frequency
converter to building ground is lower than the
grounding impedance of the machine. Make a
direct ground connection between the motor and
load motor.
•
•
Apply conductive lubrication
If the temperature of the brake resistor is too high and
the thermal switch drops out, the frequency converter
stops braking. The motor coasts.

4.6.6 Motor Thermal Protection
The electronic thermal relay in the frequency converter has
received UL-approval for single motor protection, when
1-90 Motor Thermal Protection is set for ETR Trip and
1-24 Motor Current is set to the rated motor current (see
the motor name plate).
For thermal motor protection, it is also possible to use the
MCB 112 PTC Thermistor Card option. This card provides
ATEX certificate to protect motors in explosion hazardous
areas, Zone 1/21 and Zone 2/22. When 1-90 Motor Thermal
Protection, set to [20] ATEX ETR, is combined with the use
of MCB 112, it is possible to control an Ex-e motor in
explosion hazardous areas. Consult the Programming Guide
for details on how to set up the frequency converter for
safe operation of Ex-e motors.

power supply is needed, remove the jumpers and connect
the supply to terminals 100 and 101. Protect with a 5 A. In
UL applications, use a LittelFuse KLK-5 or equivalent.
4.7.3 Power and Control Wiring for
Unscreened Cables
WARNING
INDUCED VOLTAGE
Induced voltage from coupled output motor cables
charges equipment capacitors even with the equipment
turned off and locked out. Run motor cables from
multiple frequency converters separately. Failure to run
output cables separately could result in death or serious
injury.
CAUTION
COMPROMISED PERFORMANCE
The frequency converter runs less efficiently if wiring is
not isolated properly. To isolate high frequency noise,
the following in separate metallic conduits:
Table 4.6 Terminal Functions
Ensure that the power supply can supply the necessary
current to the frequency converter.
If the unit is without built-in fuses, ensure that the
appropriate fuses have the correct current rating.

•
power wiring
motor wiring
control wiring
Failure to isolate these connections could result in less
than optimum controller and associated equipment
performance.
Because the power wiring carries high frequency electrical
pulses, it is important to run input power and motor
power in separate conduit. If incoming power wiring is in
the same conduit as motor wiring, these pulses can couple
electrical noise back onto the power grid. Isolate control
wiring from high-voltage power wiring.

individual motor in systems with parallel-connected
motors. Provide further motor protection with
thermistors in each motor or individual thermal relays.
Circuit breakers are not suitable as protection.
Illustration 4.17 Installations with Cables Connected in a

Problems are possible at start and at low RPM values if
motor sizes vary widely. The relatively high ohmic
resistance in the stator of small motors calls for a higher
voltage at start and at low RPM values.
4.9.3 Motor Thermal Protection
The electronic thermal relay in the frequency converter has
received UL-approval for single motor protection, when
1-90 Motor Thermal Protection is set for [4] ETR Trip 1 and
1-24 Motor Current is set to the rated motor current (see

NOTICE
130BT310.11
When changing the function of S201, S202 or S801 do
not use force for the switch-over. Remove the LCP cradle
when operating the switches. The switches must not be
operated with power on the frequency converter.
NOTICE
Each repeater functions as a node within the segment in
which it is installed. Each node connected within a given
network must have a unique node address, across all
segments.
Terminate each segment at both ends, using either the
termination switch (S801) of the frequency converters or a
biased termination resistor network. Always use screened
twisted pair (STP) cable for bus cabling, and always follow
good common installation practice.
Low-impedance ground connection of the screen at every
node is important, including at high frequencies. Thus,
connect a large surface of the screen to ground, for
example with a cable clamp or a conductive cable gland. It
may be necessary to apply potential-equalizing cables to
maintain the same ground potential throughout the
network - particularly in installations with long cables.
To prevent impedance mismatch, always use the same
type of cable throughout the entire network. When
connecting a motor to the frequency converters, always
use screened motor cable.

NOTICE
In applications where the motor is used as a brake, energy
is generated in the motor and sent back into the
frequency converter. If the energy cannot be transported
back to the motor, it increases the voltage in the
frequency converter DC line. In applications with frequent
braking and/or high inertia loads, this increase may lead to
an overvoltage trip in the frequency converter and finally a
shut down. Brake resistors are used to dissipate the excess

Enter line to line back EMF of PM Motor at 1000
RPM mechanical speed (RMS value). Back EMF is
the voltage generated by a PM motor when no
drive is connected and the shaft is turned
externally. Back EMF is normally specified for
nominal motor speed or for 1000 RPM measured
between 2 lines. If the value is not available for a
motor speed of 1000 RPM, calculate the correct
value as follows: If back EMF is e.g. 320 V at 1800
RPM, it can be calculated at 1000 RPM as follows:
Back EMF = (Voltage / RPM)*1000 =
(320/1800)*1000 = 178. This is the value that
must be programmed for 1-40 Back EMF at 1000
RPM.
Rotor detection
This function is the recommended choice for applications
where the motor starts from standstill, e.g. pumps or
conveyors. On some motors, an acoustic sound is heard
when the impulse is sent out. This does not harm the
motor.
Parking
This function is the recommended choice for applications
where the motor is rotating at slow speed eg. windmilling
in fan applications. 2-06 Parking Current and 2-07 Parking
Time can be adjusted. Increase the factory setting of these
parameters for applications with high inertia.
Start the motor at nominal speed. If the application does
not run well, check the VVC+ PM settings. Recommendations in different applications can be seen in Table 5.7.

7.2.3 Alarm Trip-lock
An alarm that causes the frequency converter to trip-lock
requires that input power is cycled. The motor coasts to a
stop. The frequency converter logic continues to operate
and monitors the frequency converter status. Remove
input power to the frequency converter and correct the
cause of the fault, then restore power. This action puts the
frequency converter into a trip condition as described in
chapter 7.2.2 Alarm Trip and may be reset in any of the 4
ways.
The frequency converter monitors the condition of its
input power, output, and motor factors as well as other
system performance indicators. A warning or alarm does
not necessarily indicate a problem internal to the
frequency converter itself. In many cases, it indicates failure

7.2.1 Warnings
A warning is issued when an alarm condition is impending
or when an abnormal operating condition is present and
may result in the frequency converter issuing an alarm. A
warning clears by itself when the abnormal condition is
removed.
7.2.2 Alarm Trip
An alarm is issued when the frequency converter is
tripped, that is, the frequency converter suspends
operation to prevent frequency converter or system
damage. The motor coasts to a stop. The frequency
converter logic continues to operate and monitors the
frequency converter status. After the fault condition is
remedied, reset the frequency converter. It is then ready to
start operation again.

warning/alarm condition, provides the probable cause for
the condition, and details a remedy or troubleshooting
procedure.
WARNING 1, 10 Volts low
The control card voltage is below 10 V from terminal 50.
Remove some of the load from terminal 50, as the 10 V
supply is overloaded. Max. 15 mA or minimum 590 Ω.
A short circuit in a connected potentiometer or improper
wiring of the potentiometer can cause this condition.
Troubleshooting
• Remove the wiring from terminal 50. If the
warning clears, the problem is with the wiring. If
the warning does not clear, replace the control
card.

WARNING/ALARM 9, Inverter overload
The frequency converter is about to cut out because of an
overload (too high current for too long). The counter for
electronic, thermal inverter protection issues a warning at
98% and trips at 100%, while giving an alarm. The
frequency converter cannot be reset until the counter is
below 90%.
The fault is that the frequency converter has run with
more than 100% overload for too long.
Troubleshooting
• Compare the output current shown on the LCP
with the frequency converter rated current.
•
Compare the output current shown on the LCP
with measured motor current.
•
Display the thermal drive load on the LCP and
monitor the value. When running above the
frequency converter continuous current rating,
the counter increases. When running below the
frequency converter continuous current rating,
the counter decreases.

WARNING/ALARM 10, Motor overload temperature
According to the electronic thermal protection (ETR), the
motor is too hot. Select whether the frequency converter
issues a warning or an alarm when the counter reaches
100% in 1-90 Motor Thermal Protection. The fault occurs
when the motor runs with more than 100% overload for
too long.
Troubleshooting
• Check for motor overheating.

•
•
62
Check if the motor is mechanically overloaded.
Check that the thermistor is connected correctly
between either terminal 53 or 54 (analog voltage
input) and terminal 50 (+10 V supply). Also check
that the terminal switch for 53 or 54 is set for
voltage. Check that 1-93 Thermistor Resource
selects terminal 53 or 54.
•
When using digital inputs 18 or 19, check that
the thermistor is connected correctly between
either terminal 18 or 19 (digital input PNP only)
and terminal 50.
•
If a KTY sensor is used, check for correct
connection between terminals 54 and 55
•
If using a thermal switch or thermistor, check that
the programming of 1-93 Thermistor Resource
matches sensor wiring.
•
If using a KTY Sensor, check the programming of
1-95 KTY Sensor Type, 1-96 KTY Thermistor Resource
and 1-97 KTY Threshold level match sensor wiring.
WARNING/ALARM 12, Torque limit
The torque has exceeded the value in 4-16 Torque Limit
Motor Mode or the value in 4-17 Torque Limit Generator
Mode. 14-25 Trip Delay at Torque Limit can change this
warning from a warning-only condition to a warning
followed by an alarm.
Troubleshooting
• If the motor torque limit is exceeded during ramp
up, extend the ramp up time.
•
If the generator torque limit is exceeded during
ramp down, extend the ramp down time.
•
If torque limit occurs while running, possibly
increase the torque limit. Make sure that the
system can operate safely at a higher torque.
•
Check the application for excessive current draw
on the motor.
WARNING/ALARM 13, Over current
The inverter peak current limit (approximately 200% of the
rated current) is exceeded. The warning lasts about 1.5 s,
then the frequency converter trips and issues an alarm.
Shock loading or quick acceleration with high inertia loads
can cause this fault. If the acceleration during ramp up is
quick, the fault can also appear after kinetic back-up. If
extended mechanical brake control is selected, trip can be
reset externally.
Troubleshooting
• Remove power and check if the motor shaft can
be turned.
•
Check that the motor size matches the frequency
converter.
•
Check parameters 1-20 to 1-25 for correct motor
data.

7.4 Warning and Alarm Definitions - Filter (Left LCP)
NOTICE
This section covers warnings and alarms on the filter side LCP. For warning and alarms for the frequency converter, see
chapter 7.3 Warnings and Alarm Definitions - Frequency Converter
A warning or an alarm is signalled by the relevant LED on the front of the filter and indicated by a code on the display.
A warning remains active until its cause is no longer present. Under certain circumstances operation of the unit may still be
continued. Warning messages may be critical, but are not necessarily so.
In the event of an alarm, the unit has tripped. To restart operation, reset the rectified alarms.
This may be done in 4 ways:
1.
By pressing [Reset].
2.
Via a digital input with the Reset function.
3.
Via serial communication/optional fieldbus.
4.
By resetting automatically using the [Auto Reset] function.
7 7
NOTICE
After a manual reset pressing [Reset], press [Auto On] or [Hand On] to restart the unit.
If an alarm cannot be reset, the reason may be that its cause has not been rectified, or the alarm is trip-locked (see also
Table 7.6).
Alarms that are trip-locked offer additional protection, meaning that the mains supply must be switched off before the
alarm can be reset. After being switched back on, the unit is no longer blocked and may be reset as described above once
the cause has been rectified.
Alarms that are not trip-locked can also be reset using the automatic reset function in 14-20 Reset Mode (Warning: automatic
wake-up is possible)
If a warning and alarm is marked against a code in Table 7.6, either a warning occurs before an alarm, or it can be specified
whether it is a warning or an alarm that is to be displayed for a given fault.
No.

Table 7.6 Alarm/Warning Code List
A trip is the action when an alarm has appeared. The trip coasts the motor and can be reset by pressing [Reset] or make a
reset by a digital input (parameter group 5-1* Digital Inputs [1] Reset). The origin event that caused an alarm cannot damage
the frequency converter or cause dangerous conditions. A trip lock is an action when an alarm occurs, which may cause
damage to frequency converter or connected parts. A Trip Lock situation can only be reset by a power cycling.

1) For type of fuse, see chapter 8.5.1 Fuses.
2) American wire gauge.
3) Measured using 5 m screened motor cables at rated load and rated frequency.
4) The typical power loss is at nominal load conditions and expected to be within ±15% (tolerence relates to
variety in voltage and cable conditions). Values are based on a typical motor efficiency (IE2/IE3 border line). Motors
with lower efficiency also add to the power loss in the frequency converter and opposite. If the switching
frequency is increased to the default setting, the power losses may rise significantly. LCP and typical control card
power consumptions are included. Further options and customer load may add up to 30 W to the losses. (Though
typical only 4 W extra for a fully loaded control card, or options for slot A or slot B, each).
Although measurements are made with state-of-the-art equipment, some measurement inaccuracy must be
allowed for (±5%).

Temperature monitoring of the heat sink ensures that the frequency converter trips if the temperature reaches a
predefined level. An overload temperature cannot be reset until the temperature of the heat sink is below the
allowed values.
•
•
•
The frequency converter is protected against short-circuits on motor terminals U, V, W.
•
If a mains phase is missing, the frequency converter trips or issues a warning (depending on the load).
Monitoring of the intermediate circuit voltage ensures that the frequency converter trips if the intermediate circuit
voltage is too low or too high.
The frequency converter is protected against earth faults on motor terminals U, V, W.

Mains voltage low/mains drop-out:
During low mains voltage or a mains drop-out, the filter continues until the intermediate circuit voltage drops below the
minimum stop level, which corresponds to 15% below the filter lowest rated supply voltage. Full compensation cannot be
expected at mains voltage lower than 10% below the filter lowest rated supply voltage. If mains voltage exceed the filter highest
rated voltage, the filter continues to work but harmonic mitigation performance is reduced. The filter does not cut out until main
voltages exceed 580 V.

Protection and features
•
Temperature monitoring of the heat sink ensures that the active filter trips if the temperature reaches a predefined
level. An overload temperature cannot be reset until the temperature of the heat sink is below the acceptable
values.
•
•
•
If a mains phase is missing, the active filter trips.
•
88
The active filter has a short circuit protection current rate of 100 kA if properly fused
Monitoring of the intermediate circuit voltage ensures that the filter trips if the intermediate circuit voltage is too
low or too high.
The active filter monitors the mains current as well as internal currents to reassure that current levels do not reach
critical levels. If current exceeds a critical level, the filter trips.

8.4.2 Derating for Altitude
The cooling capability of air is decreased at lower air
pressure.
Below 1,000 m altitude no derating is necessary but above
1,000 m the ambient temperature (TAMB) or max. output
current (Iout) should be derated in accordance with
Illustration 8.6.
An alternative is to lower the ambient temperature at high
altitudes and thereby ensure 100% output current at high
altitudes. As an example of how to read the graph, the
situation at 2,000 m is elaborated. At a temperature of 45
°C (TAMB, MAX - 3.3 K), 91% of the rated output current is
available. At a temperature of 41.7 °C, 100% of the rated
output current is available.

8.5 Fuses
It is recommended to use fuses and/or circuit breakers on
the supply side as protection in case of component breakdown inside the frequency converter (first fault).
NOTICE
This is mandatory to ensure compliance with IEC 60364
for CE or NEC 2009 for UL.
Branch circuit protection
To protect the installation against electrical and fire hazard,
all branch circuits in an installation, switch gear, machines
etc., must be protected against short-circuit and
overcurrent according to national/international regulations.
NOTICE
The recommendations given do not cover branch circuit
protection for UL.
Short-circuit protection
Danfoss recommends using the fuses/circuit breakers
mentioned below to protect service personnel and
property in case of component break-down in the
frequency converter.
Overcurrent protection
The frequency converter provides overload protection to
limit threats to human life, property damage and to avoid
fire hazard due to overheating of the cables in the installation. The frequency converter is equipped with an
internal overcurrent protection (4-18 Current Limit) that can
be used for upstream overload protection (UL-applications
excluded). Moreover, fuses or circuit breakers can be used
to provide the overcurrent protection in the installation.
Overcurrent protection must always be carried out
according to national regulations.
The following tables list the recommended rated current.
Recommended fuses are of the type gG for small to
medium power sizes. For larger powers, aR fuses are
recommended. Circuit breakers must be used, provided
they meet the national/international regulations and they
limit the energy into the frequency converter to an equal
or lower level than the compliant circuit breakers.
If fuses/circuit breakers according to recommendations are
selected, possible damage on the frequency converter is
mainly limited to damage inside the unit.
Non UL compliance
If UL/cUL is not to be complied with, use the following
fuses, which ensure compliance with EN50178:
P160-P250
380-480 V
type gG
P315-P450
380-480 V
type gR
Table 8.5 Fuse Types by Power Range
WARNING
Protect personnel and property against the consequence
of component break-down internally in the frequency
converter.
