Electrical connection

Note
Only the enclosure cover may be opened when electrically connecting the Voltage Protection
Module.
Introduction
Various types of cabling work must be carried out in order to integrate a Voltage Protection
Module into a motor feeder circuit. All connections must be set up inside the VPM housing.
Cable cross-sections are determined by the rated motor power and may be as much as 2 x
50 mm
below. It is particularly relevant for larger cross-sections.
Preparation
The following preparations must be made before setting up connections:
● Loosen the 4 screws on the cover of the housing, so that the cover can be shifted in the
cutouts.
● Move the enclosure cover to the point where the cutout widens out so it can be lifted over
the screw heads.
● Attach the cable glands for the signal cable and power cables (2x for the VPM120, 4x for
the VPM200) at the entries into the housing of the Voltage Protection Module.
● Remove 300 mm of the cable sheath of the power cables and expose the shield to match
the housing gland being used.
● Remove the insulation at the ends of the individual conductors and attach cable lugs.
● Attach the signal cable to X3 and secure the cable with cable ties inside the Voltage
Protection Module.
