[ PRECAUTIONS ]
1. Use round crimp-style terminals for connecting wires to the power supply terminal block.
(Refer to Fig. 23)
If unavailable, observe the following points when wiring.
• Do not connect wires of different gauge to the same power supply terminal.
(Looseness in the connection may cause overheating.)
• Use the specifi ed electric wire. Connect the wire securely to the terminal. Lock the wire down without
applying excessive force to the terminal. (Tightening torque: 0.97ft.lbf ±10 %)
2. Tightening torque for the terminal screws.
• 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 tightened.
• If the terminal screws are tightened too hard, screws might be damaged.
• Refer to the table below for the tightening torque of the terminal screws.

Forced off terminal block (6P)
Power supply and Ground terminal block (3P)
3. Do not connect wires of different gauge to the same ground terminal. Looseness in the connection may
lessen protection.
4. Keep transmission wiring at least 5" away from power supply wiring. The equipment may malfunction if
subjected to electrical (external) noise.
5. For remote controller wiring, refer to the "INSTALLATION MANUAL OF REMOTE CONTROLLER" at-
tached to the remote controller.
