3.4 Mounting the Power Modules
Take note of the following listed specifications when installing the Power Module.
Protection against the spread of fire
The device may be operated only in closed housings or in control cabinets with protective
covers that are closed, and when all of the protective devices are used. The installation of
the device in a metal control cabinet or the protection with another equivalent measure must
prevent the spread of fire and emissions outside the control cabinet.
Protection against condensation or electrically conductive contamination
Protect the device, e.g. by installing it in a control cabinet with degree of protection IP54
according to IEC 60529 or NEMA 12. Further measures may be necessary for particularly
critical operating conditions.
If condensation or conductive pollution can be excluded at the installation site, a lower
degree of control cabinet protection may be permitted.
Installing
Rules for admissible mounting:
● Only mount the Power Module in a vertical position with the motor connectors at the
