To attach the other end of the PGND cable to the grounding strip in the equipment room, follow these
steps:
1) Cut the PGND cable to a proper length according to the distance between the switch and the
grounding strip.
2) Peel 5 mm (0.2 in.) of insulation sheath using a wire stripper, and then insert the naked metal part
through the black insulation covering into the end of the OT terminal. (Two OT terminals are
provided with the PGND cable when shipped with the switch; select a proper OT terminal according
to the size of the grounding post.)
3) 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.
4) Connect the OT terminal to the grounding pole of the grounding strip, and then fasten it with a hex
nut.
