WARNING

DANGER OF BODILY INJURY OR DEATH

TURN OFF ELECTRIC POWER AT CIRCUIT BREAKER OR POWER SOURCE BEFORE
MAKING ANY ELECTRIC CONNECTIONS. GROUND CONNECTIONS MUST BE
COMPLETED BEFORE MAKING LINE VOLTAGE CONNECTIONS.

(1) Selection of size of power supply and interconnecting wires.

Precautions for Electric wiring

Electric wiring work should be conducted only by authorized personnel.
Do not connect more than three wires to the terminal block. Always use round type crimped terminal
lugs with insulated grip on the ends of the wires.
Use copper conductor only.

Select wire sizes and circuit protection from table below. (This table shows 20 m length wires with
less than 2% voltage drop.)
