Precautions to be taken for power supply wiring
Use a round crimp-style terminal for connection to the power supply terminal block. (Refer to Fig. 22)
In case it cannot be used due to unavoidable reasons, be sure to observe the following instructions.
• Do not connect wires of different gauge to the same power supply terminal. (Looseness in the connection
may cause overheating.) (Refer to Fig. 23)
• In wiring, make certain that prescribed wires are used. Also, fix the wires so that external force may not be
applied to the terminals.
Tightening torque for the terminal screws.
• Use an appropriate screwdriver to tighten 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 5 for the tightening torque of the terminal screws.
