connections in the power section (Mains ① , Motor ②).
Guide holes are provided for an external braking resistor. In the housing

In order to be able to drill further bushings, please loosen the two screws [1]
and remove the housing cover [2].
To drill holes in the metal connection plate, loosen the four screws [3] and
remove the connection plate [4]. You can now drill further holes without
chips getting into the inside of the device.
Installaling the cable glands
Insert a plastic gland into the knockout on the left – which could already have
been punched out at the factory – in order to thread in the power supply
cord. Due to EMC reasons, you should use an metallic EMC cable gland in
the knockout on the right in order to connect the motor cable screen across a
large area and ground it.
