All wiring activities should be performed while power is OFF.
Use over-current protection, such as a fuse or circuit breaker, to avoid excessive
currents into the UIS-WCB1 module supply port.
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
2
–3.31 mm
2
).
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.
