36 Mechanical installation
Installing
The instructions in this manual cover drives with the IP20 degree of protection. To
comply with NEMA 1, use the MUL1-R1, MUL1-R3 or MUL1-R4 option kit, which is
delivered with multilingual installation instructions (3AFE68642868, 3AFE68643147
or 3AUA0000025916, respectively).
To obtain a higher degree of protection, the drive must be installed inside a cabinet. If
there are sand, dust or other impurities in the operating environment, a typical
minimum requirement for the installation cabinet is IP54 degree of protection.

Install the drive
Install the drive with screws or on a DIN rail as appropriate.
Note: Make sure that dust from drilling does not enter the drive during the installation.
With screws
1. Mark the hole locations using for example the mounting template cut out from the
package. The locations of the holes are also shown in the drawings in chapter
Dimension drawings on page 395 . The number and location of the holes used
depend on how the drive is installed:
a) back mounting (frame sizes R0…R4): four holes
b) side mounting (frame sizes R0…R2): three holes; one of the bottom holes is
located in the clamping plate.
2. Fix the screws or bolts to the marked locations.
3. Position the drive onto the screws on the wall.
4. Tighten the screws in the wall securely.
