For information about dimensions, drilling templates, minimum clearances and
tightening torques, please refer to the Operating Instructions for the Control Unit
(A5E34257946A AB).
IP20 devices
IP20 devices must be protected against conductive pollution, e.g., by installing
them in a control cabinet with IP54 degree of protection according to IEC 60529
or NEMA 12. Provided conductive pollution can be prevented at the installation
site, the degree of protection for the cabinet can be decreased accordingly.
1. Position the Power Module in the control cabinet so that you can connect the
cables for the motor and line supply in accordance with the terminal layout.
Please note that the Power Module must always be mounted vertically.
2. Please use the fixing materials supplied in order to mount the Power Module in
the control cabinet. Please observe the following:
– Maintain the minimum required clearances to other components in the
control cabinet.
– Do not exceed the maximum specified tightening torques for fastenings.

IP55 devices
To ensure the cooling capacity, IP55 devices in frame sizes FSA to FSC must be
mounted directly onto a flat wall. If this is not possible, for example in the case of
a suspended installation on a busbar system, an air guide sheet (available
separately) must be attached.
The variable speed drive must be mounted on an unpainted metal surface in
order to comply with EMC requirements.
