How to Insulation tube.
• Use the insulation tube large to cover the power supply
wiring.
Use the insulation tube small to cover the transmission
wiring.
• Joint the insulation tube with the tape and cut off the tube

CAUTION
• After fi nishing the electric wiring work, confi rm that all the
wirings are connected securely.
〈〈Precautions when laying power wiring〉〉
• Two electric wires of different thickness cannot be connected
to the power terminal block.
(Slack in the electric wires may generate abnormal heat.)
• Use round pressure terminals with insulting sleeve for
connection to the power terminal block.
If such terminals are not available for unavoidable reasons,
connect an electric wire of the same thickness to each side
as shown in the fi gure.

Make sure to observe the following items. If they are not
observed, abnormal heat may be generated by slack in electric
wires, etc.
• For wiring, use the designated power wire and connect
fi rmly, then secure to prevent outside pressure being exerted
on the terminal board.
• Use an appropriate screwdriver for tightening the terminal
screws.
A screwdriver with a small head will strip the head and make
proper tightening impossible.
• Over-tightening the terminal screws may break them.
• See the table below for tightening torque for the terminal
screws.
