Installing the motor starter
Carry out the following steps to install the motor starter:
Step
Description
1
Find a flat surface for mounting the device.
2
Drill four holes for the screws.
3
Secure the motor starter using four screws (M5). If necessary, use plain washers and
spring washers.
4.1.5
Functional ground
The motor starter must be connected to functional ground. The connection to functional
ground is required to discharge interference and ensure EMC resistance. Unlike the
protective conductor, functional ground does not offer protection against electric shock,
which is why it must be routed separately.
The contact plate at the fixing point on the bottom right is connected to functional ground
The contact plate at the fixing point on the bottom right is connected to functional ground
within the device. This connection must be connected to the ground potential with as little
resistance as possible.

Connection for functional ground
If you do not install the motor starter on a grounded, conductive base, you have to establish
a connection with the ground potential (grounding cable with cable lug, spring washer, and
plain washer).
