FLANGE MOUNT KITS FOR MR4-MR7
MOUNTING INSTRUCTIONS
GENERAL
Using the optional Flange Mounting Kit, you can mount the AC drive through a cabinet wall or
similar surface so that the control unit of the drive remains inside the cabinet.
The correct installation of the Flange Mounting Kit might affect the IP protection class of the AC
drive. If the drive is protected according to an IP54/Type12, or the drive is supplied with the flange
option at the factory, you only need to install the collars, as instructed. However, the power module
of an IP21/Type1-protected drive will only become protected according to the IP54/Type12 on the
rear side (see figure below), if all parts of the flange mounting kit are installed properly. The need
for this has to be evaluated and these actions are explained in this guide.

It is recommended that the embossed holes or self clinching nuts are used in the back plate for the
drive mounting in order to guarantee the sealing.

MR4 FLANGE MOUNTING
If your drive is IP21/Type1-protected and there is the risk that dust or other impurities in the cooling
air might end up inside the control unit, start the mounting with actions described in steps 1 to 4.
If this is not needed, install the flange mounting kit proceeding directly to step 5. Note, in this case
the rear will not be according to the IP54/Type12.
