Installing Power Modules
Installing Power Modules
The following is required to correctly install a Power Module:
● Install the Power Module in a control cabinet.
● Install the Power Module vertically with the line and motor connections facing downwards.
● Comply with the installation regulations specified in the following sections:
– Minimum clearances to other components
– Fixing elements
– Tightening torques for fixing elements
Protection against the spread of fire
The inverter may be operated only in closed housings or in higher-level control cabinets with
protective covers that are closed, and when all of the protective devices are used. The
installation of the inverter 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 inverter, 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.
