To attach the other end of the PGND cable to the grounding strip in the equipment room, follow these
steps:
Step1 Cut the PGND cable to a proper length according to the distance between the switch and the grounding
strip.
Step2 Peel 5 mm (0.20 in.) of insulation sheath using a wire stripper, and then insert the naked metal part
through the insulation covering into the end of the OT terminal.
Step3 Secure the metal part of the cable to the OT terminal with a crimper, and then cover it with the insulation
covering. Then heat the insulation covering with a blowing machine to let it completely cover the metal
part.
Step4 Connect the OT terminal to the grounding pole of the grounding strip, and then fasten it with a hex nut.
