1.4 Product Overview
A frequency converter is an electronic motor controller
that converts AC mains input 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 position sensors on a
conveyor belt. The frequency converter can also regulate
the motor by responding to remote commands from
external controllers.
In addition, the frequency converter monitors the system
and motor status, issues warnings or alarms for fault
conditions, starts and stops the motor, optimizes energy
efficiency, and offers many more control, monitoring, and
efficiency functions. Operation and monitoring functions
are available as status indications to an outside control
system or serial communication network.

525-690 At altitudes above 2 km, contact Danfoss regarding
PELV
Table 2.1 Installation in High Altitudes
2.2 Pre-Installation Check List
•Before unpacking the frequency converter, ensure
the packaging is intact. If any damage has
occurred, immediately contact the shipping
company to claim the damage.
•Before unpacking the frequency converter, locate
it as close as possible to the final installation site
•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 that frequency converter output current
rating is equal to or greater than 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
motor, full motor output cannot be
achieved
2.3 Mechanical Installation
2.3.1 Cooling
•Top and bottom clearance for air cooling must be
provided. Generally, 225 mm (9 in) is required.
•Improper mounting can result in over heating
and reduced performance
•Derating for temperatures starting between 45 °C
(113 °F) and 50 °C (122 °F) and elevation 1000 m
(3300 ft) above sea level must be considered. See
VLT
®
Design Guide for detailed information.
The high power frequency converters utilise a back-
channel cooling concept that removes heatsink cooling air,
which carries approximately 90% of the heat out of the
back channel of the frequency converters. The back-
channel air can be redirected from the panel or room
using one of the kits below.
Duct cooling
A back-channel cooling kit is available to direct the
heatsink cooling air out of the panel when an IP20/chassis
frequency converters is installed in a Rittal enclosure. Use
of this kit reduces the heat in the panel and smaller door
fans can be specified on the enclosure.
Cooling out the back (top and bottom covers)
The back channel cooling air can be ventilated out of the
room so that the heat from the back channel is not
dissipated into the control room.
A door fan(s) is required on the enclosure to remove the
heat not contained in the backchannel of the frequency
converters and any additional losses generated by other
components inside the enclosure. The total required air
flow must be calculated so that the appropriate fans can
be selected.

For your safety, comply with the following requirements
•Electronic controls equipment is connected to
hazardous mains voltage. Extreme care should be
taken to protect against electrical hazards when
applying power to the unit.
•Run motor cables from multiple frequency
converters multiple frequency converters
separately. Induced voltage from output motor
cables run together can charge equipment
capacitors even with the equipment turned off
and locked out.
•Field wiring terminals are not intended to receive
a conductor one size larger.
Overload and Equipment Protection
•An electronically activated function within the
frequency converter provides overload protection
for the motor. The overload calculates the level of
increase to activate timing for the trip (controller
output stop) function. The higher the current
draw, the quicker the trip response. The overload
provides Class 20 motor protection. See
8 Warnings and Alarms for details on the trip
function.
•Because the motor wiring carries high frequency
current, it is important that wiring for mains,
motor power, and control are run separately. Use
metallic conduit or separated shielded wire. See
Illustration 2.3. Failure to isolate power, motor,
and control wiring could result in less than
optimum equipment performance.
•All frequency converters must be provided with
short-circuit and over-current protection. Input
fusing is required to provide this protection, see
Illustration 2.4. If not factory supplied, fuses must
be provided by the installer as part of installation.
See maximum fuse ratings in 10.3.1 Protection.

Wire Type and Ratings
•All wiring must comply with local and national
regulations regarding cross-section and ambient
temperature requirements.
•Danfoss recommends that all power connections
be made with a minimum 75 °C rated copper
wire.
2.4.2 Earth (Grounding) Requirements
WARNING
EARTHING (GROUNDING) HAZARD!
For operator safety, it is important to earth (ground) the
frequency converter properly in accordance with national
and local electrical codes as well as instructions contained
within this document. Do not use conduit connected to
the frequency converter as a replacement for proper
grounding. Earth (ground) currents are higher than 3.5 mA.
Failure to earth (ground) the frequency converter properly
could result in death or serious injury.
NOTE
It is the responsibility of the user or certified electrical
installer to ensure correct earthing (grounding) of the
equipment in accordance with national and local electrical
codes and standards.
•Follow all local and national electrical codes to
earth (ground) electrical equipment properly
•Proper protective earthing (grounding) for
equipment with earth (ground) currents higher
than 3.5 mA must be established, see
2.4.2.1 Leakage Current (>3.5 mA)
•A dedicated earth wire (ground wire) is required
for input power, motor power and control wiring
•Use the clamps provided with the equipment for
proper earth connections (ground connections)
•Do not earth (ground) one frequency converter to
another in a “daisy chain” fashion
•Keep the earth (ground) wire connections as
short as possible
•Using high-strand wire to reduce electrical noise
is recommended
•Follow motor manufacturer wiring requirements
2.4.2.1 Leakage Current (>3.5 mA)
Follow national and local codes regarding protective
earthing of equipment with a leakage current >3.5 mA.
Frequency converter technology implies high frequency
switching at high power. This will generate a leakage
current in the earth connection. A fault current in the
frequency converter at the output power terminals might
contain a DC component, which can charge the filter
capacitors and cause a transient earth current. The earth
leakage current depends on various system configurations
including RFI filtering, screened motor cables, and
frequency converter power.
EN/IEC61800-5-1 (Power Drive System Product Standard)
requires special care if the leakage current exceeds 3.5 mA.
Earthing (grounding) must be reinforced in one of the
following ways:
•Earth (ground) wire of at least 10 mm2
•Two separate earth (ground) wires both
complying with the dimensioning rules

WARNING
INDUCED VOLTAGE!
Run output motor cables from multiple frequency
converters separately. Induced voltage from output motor
cables run together can charge equipment capacitors even
with the equipment turned off and locked out. Failure to
run output motor cables separately could result in death
or serious injury.
•For maximum cable sizes, see 10.1 Power-
dependent Specifications
•Comply with local and national electrical codes
