Precautions on wiring of power supply
• Use a round crimp-style terminal for connection to the power supply terminal board. In case it cannot be used due to unavoidable
reasons, be sure to observe the following instructions.
•
Do not connect different gauge wires to the same power supply terminal. (Loose connections may cause overheating.)
•
When connecting wires of the same gauge, connect them according to the figure below.
• Use the correct screwdriver to tighten the terminal screws. Small screwdrivers can damage the screw head and prevent
appropriate tightening.
• Over-tightening the terminal screws can damage the screws.
•
Attach a ground fault circuit interrupter and fuse to the power supply line.
•
In wiring, make certain that prescribed wires are used, carry out complete connections, and fix the wires so that outside force
cannot affect the terminals.
