To attach the other end of the grounding cable to the grounding strip:
4. Cut the grounding cable as appropriate for connecting to the grounding strip.
5. Peel 5 mm (0.20 in) of insulation sheath by using a wire stripper, and insert the bare metal part
through the black insulation covering into the end of the OT terminal.
6. Secure the metal part of the cable to the OT terminal with a crimper, cover the joint with the
insulation covering, and heat the insulation covering with a blow dryer to completely cover the
metal part.
7. Connect the OT terminal to the grounding pole of the grounding strip, and fasten it with a hex nut.

CAUTION:
Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a fire
main or lightning rod.
Grounding the switch with a grounding conductor buried in the
earth ground
If the installation site has no grounding strips, but earth ground is available, hammer a 0.5 m (1.64 ft) or
longer angle iron or steel tube into the earth ground to serve as a grounding conductor.
The angle iron must have a dimension no less than 50 × 50 × 5 mm (1.97 × 1.97 × 0.20 in) and the steel
tube must have a wall thickness no less than 3.5 mm (0.14 in) and be zinc-coated.
Weld the yellow-green grounding cable to the angel iron or steel tube and treat the joint for corrosion
protection.
