Wiring

 This equipment is designed to operate only at SELV/PELV/Class 2/Limited Power
environments.
 All power supplies in the system must include double insulation. Power supply
outputs must be rated as SELV/PELV/Class 2/Limited Power.
 Do not connect either the 'Neutral' or 'Line' signal of the 110/220VAC to device's 0V
point.
 Do not touch live wires.
 All wiring activities should be performed while power is OFF.
 Unused points should not be connected (unless otherwise specified). Ignoring this
directive may damage the device.
 Double-check all wiring before turning on the power supply.
Caution  To avoid damaging the wire, use a maximum torque of 0.5 N·m (5 kgf·cm).
 Do not use tin, solder, or any substance on stripped wire that might cause the
wire strand to break.
 Install at maximum distance from high-voltage cables and power equipment.

Wiring Procedure

Use crimp terminals for wiring; use 26-12 AWG wire (0.13 mm
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 a proper connection.
4. Tighten enough to keep the wire from pulling free.
