6. Check the hold of the wires in the terminals by lightly pulling on
them
7. Connect the screen to the internal ground terminal, connect the
outer ground terminal to potential equalisation in case of power
supply via low voltage
8. Connect the lead cable for power supply in the same way accord-
ing to the wiring plan, in addition connect the ground conductor to
the inner ground terminal when powered with mains voltage.
9. Tighten the compression nut of the cable glands. The seal ring
must completely encircle the cables
