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).

Install the drive
Install the drive with screws or on a DIN rail as appropriate.
The required free space for cooling above and below the drive is 75 mm (3 in). No
free space is required on the sides, so drives can be mounted immediately next to
each other.
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 in ACS320 user's manual (3AUA0000062599 [English]). 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.
