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.
