Wiring Considerations

•
Do not use tin, solder or any other substance on the stripped wire that might cause the wire strand to break.
• We recommend that you use crimp terminals for wiring.
• Install at maximum distance from high-voltage cables and power equipment.

General Wiring Procedures

1 Strip the wire to a length of 7±0.5mm (0.250–0.300 inches).
2 Unscrew the terminal to its widest position before inserting a wire.
3 Insert the wire completely into the terminal to ensure that a proper connection
can be made.
4 Tighten enough to keep the wire from pulling free.
To avoid damaging the wire, do not exceed a maximum torque of 0.5 N·m (5 kgf·m).
•
Do not touch live wires.
• Double-check all the wiring before turning on the power supply.
