7 FIELD WIRING WARNING A main switch or other means of disconnection, having a contact separation in all poles, must be incorporated in the fixed wiring in accordance with relevant local laws and regulations. Switch off the power supply before making any connections.
Fig. -1 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.
