4 Mounting

Information
Mount the VARIPACK frequency inverter always
vertically.
The fixtures for the power cables and control cables are
delivered as standard in the accessories kit and must
be mounted together with the ferrite core or the ferrite
cores (see figure 11, page 18) up to VARIPACK hous-
ing size FJU+145, in order to achieve the EMC
class C2 according to EN61800-3.

4.1 Transport and storage

NOTICE
!
!
Risk of damage to the VARIPACK frequency in-
verter!
Do not lift or set down the VARIPACK fre-
quency inverter at the connections.
Place it on clean, flat and dry surfaces only.
Storage in well-ventilated places and protected
from high temperatures, moisture, dust and
metal particles only!
Storage temperature: -25°C .. +55°C.
Transport temperature: -25°C .. +70°C.

4.2 Ventilation

NOTICE
!
!
The VARIPACK frequency inverters give off
heat in operation.
Insufficient or blocked air circulation and air sup-
ply at the ventilation slots and at the heat sink of
the VARIPACK frequency inverter can lead to
failure due to overheating!
Observe the minimum clearances for ventilation
(see figure 2, page 7)!
When two or more VARIPACK frequency invert-
ers are mounted side by side, add up the clear-
ances!
When using filter fans, the required air volume flow
3
(m /h) must be carefully determined to ensure sufficient
cooling of all electrical devices in the switch cabinet.
For protection from temperatures below 0°C and for
avoiding condensation, a switch cabinet heater may be
required, depending on the installation site and the cli-
matic conditions.
Rated values of the VARIPACK fans, see table 1, page
5.
