• Shape the wires and attach the control box lid securely so that wires will not be caught.
(Caught wires and risen lid may cause an electric shock or fire.)
Precautions to be taken for power supply wiring
Use a round crimp-style terminal for connection to the power supply terminal block.
In case it cannot be used due to unavoidable reasons, be sure to observe the following instructions.
(Refer to Fig. 27)
• Do not connect wires of different gauge to the same power supply terminal. (Looseness in the connection
may cause overheating.) (Refer to Fig. 28)
• When connecting wires of the same gauge, connect them according to. (Refer to Fig. 28)
• In wiring, make certain that prescribed wires are used, carry out complete connections, and fix the wires so
that external forces are not applied to the terminals.
Connect wires of the
same gauge to both
side. (GOOD)

• Use the correct screw driver 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.
