〈 Precautions when laying power supply wiring 〉
• Wiring of different thicknesses cannot be connected to the
power supply wiring terminal block. (Slack in the power
supply wiring may cause abnormal heat.)
• Use sleeve-insulated round crimp-style terminals for con-
nections to the power supply wiring terminal block. When
none are available, connect wires of the same diameter to
both sides, as shown in the following figure.
Follow the instructions below if the wiring gets very hot
due to slack in the power supply wiring.
•For wiring, use the designated power supply wiring and
connect firmly, then secure to prevent outside pressure
being exerted on the terminal board.
• Use the correct screwdriver for tightening the terminal screws.
If the blade of screwdriver is too small, the head of the screw
might be damaged, and the screw will not be properly tight-
ened.
• If the terminal screws are tightened too hard, screws might
be damaged.
• Refer to the following below for the tightening torq
ue of the
terminal screws.
