wirings of same
must be carried out
on both sides.
• N ever use the stranded wiring which is soldered.
(Slack in the electric wiring may cause abnormal heat.)
• Use the required wirings, connect them securely and fix these wirings so that
external force may not apply to the terminals.
• Use a proper screw driver for tightening the terminal screws.
If an improper screw driver is used, it may damage the screw head and a proper
tightening cannot be carried out.
• If a terminal is over tightened, it may be damaged. Refer to the table shown below
for tightening torque of terminals.
Precautions when connecting the earth terminal
