elevation 1000 m (3300 ft) above sea level. See
the frequency converter design guide for detailed
information.
The frequency converter utilizes a back-channel cooling
concept that removes heat sink cooling air. The heat sink
cooling air carries approximately 90% of the heat out of
the back channel of the frequency converter. Redirect the
back-channel air from the panel or room by using:
•Duct cooling. A back-channel cooling kit is
available to direct the heat sink cooling air out of
the panel when an IP20/chassis frequency
converter is installed in a Rittal enclosure. Use of
Mechanical Installation VLT®AQUA Drive FC 202
10 Danfoss A/S © 11/2016 All rights reserved. MG21A402
33

this kit reduces the heat in the panel and smaller
door fans can be specied on the enclosure.
•Cooling out the back (top and base 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.
NOTICE
One or more door fans are required on the enclosure to
remove the heat not contained in the back channel of
the frequency converter. The fans also remove any
additional losses generated by other components inside
the frequency converter. To select the appropriate fan,
calculate the total required airow.
Secure the necessary airow over the heat sink. The ow
rate is shown in Table 3.2.
Enclosure size Door fan/top fan Heat sink fan

NOTICE
EMC INTERFERENCE
Use shielded cables for motor and control wiring, and
separate cables for mains input, motor wiring, and
control wiring. Failure to isolate power, motor, and
control cables can result in unintended behavior or
reduced performance. Minimum 200 mm (7.9 in)
clearance between mains input, motor, and control
cables is required.
4.5 Access
All terminals to the control cables are located underneath
the LCP inside the frequency converter. To access, open the
door (IP21/54) or remove the front panel (IP20).
4.6 Motor Connection
WARNING
INDUCED VOLTAGE
Induced voltage from output motor cables that run
together can charge equipment capacitors, even with the
equipment turned o and locked out. Failure to run
output motor cables separately or use shielded cables
could result in death or serious injury.
•Comply with local and national electrical codes
for cable sizes. For maximum wire sizes, see
chapter 8.1 Electrical Data.
•Follow motor manufacturer wiring requirements.
•Motor wiring knockouts or access panels are
provided at the base of IP21 (NEMA1/12) and
higher units.
•Do not wire a starting or pole-changing device
(for example Dahlander motor or slip ring
asynchronous motor) between the frequency
converter and the motor.
Procedure
1. Strip a section of the outer cable insulation.
2. Position the stripped wire under the cable clamp
to establish mechanical xation and electrical
contact between the cable shield and ground.
3. Connect the ground wire to the nearest
grounding terminal in accordance with the
grounding instructions provided in
chapter 4.3 Grounding, see Illustration 4.4.
4. Connect the 3-phase motor wiring to terminals
96 (U), 97 (V), and 98 (W), see Illustration 4.4.
5. Tighten the terminals in accordance with the
information provided in chapter 8.8 Connection
Tightening Torques.
