Connection diagram for DUAL option

Cable gland assembly and power line connection

If you are not using the recommended cable lugs, select cable lugs that leave 10 mm gap

between each and every cable lug on the same connection plate.

The pictures are schematic, and the actual components can look different.

This Chapter describes how to assemble screened power cables to the electric machine. See the cable
glands recommendations from the Table below. Cable gland assembly instruction can also be found from
PFLITSCH gland catalog available from

http://www.pflitsch.de

Use correct type of gland for different cable diameters. These are shown in the Table below.
