4.3 Installing Power Modules
Mounting Power Modules using through-hole technology
We recommend that you use the optionally available mounting frame to mount the push-
through unit 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.
Procedure
Proceed as follows to correctly mount the Power Module:
1. Prepare the cutout and the mounting holes for the Power
Module and the mounting frame corresponding to the
dimension drawings of the mounting frame.
2. Position the mounting frame at the rear of the control
cabinet and attach it to the control cabinet by tightening
the corresponding screws by hand.
3. Attach the seal to the inner side of the control cabinet.
4. Mount the frequency inverter and initially tighten all of
the mounting screws by hand.
5. Tighten the screws with a torque of 3 Nm.
You have correctly mounted the Power Module.
Mounting additional components
Depending on the application, the following additional components, for example, may be
required (also refer to Section Description (Page 25)):
