2) Connect the ground kit to the feeder, and lift up to where the covering of the feeder is

stripped off.

3) Wrap the cable of the ground kit about by 7~10 cm with the vinyl tape, and wrap the

cable by using the insulation tape again.

4) Fix the driven rod(GND BAR) in the ground kit and the iron tower copper rod by

using the copper bolt.
