Note
Only the enclosure cover may be opened when electrically connecting the Voltage Protection
Module.
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
2
for each conductor. An installation sequence for individual conductors is outlined
below. It is particularly relevant for larger cross-sections.
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.
