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
Mounting Power Modules in push through technology (PT Power Module)
We recommend that you use the optional mounting frames when installing PT Power
Modules in a control cabinet. This mounting frame includes the necessary seals and frame to
ensure compliance with degree of protection IP54.
If you do not use the optional mounting frames, then you must ensure that the required
degree of protection is complied with using other appropriate measures.
You must mount the inverter on unpainted metal surfaces in order to comply with EMC
requirements.
