〈〈
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.

Round pressure terminal
Attach insulation sleeve
Connect same-
thickness wiring
to both sides.
It is forbidden
to connect two
to one side.
It is forbidden to
connect wiring of
different thicknesses.
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.
