Wiring Procedures

• Use crimp terminals for wiring.

• Use 26-12 AWG wire (0.13 mm

–3.31 mm

) for all wiring.

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 use tin, solder, or any other substance on stripped

wire that might cause the wire strand to break.

Install at maximum distance from high-voltage cables and

power equipment.

I/O Wiring—General

• Input or output cables should not:

• be run through the same multi-core cable

• share the same wire.

• Allow for voltage drop and noise interference with input lines used

over an extended distance.

• Use wire that is properly sized for the load.

Digital Inputs

• Each group of eight inputs:

• has a common signal

• can be used as pnp (source) or npn (sink) when appropriately

wired as shown in FIGURE 4-2.

• Inputs I0 through I8 can be used to reset a latched zone relay.

• Input I11 can be used to reset a latched relay on a remote sensor.

• Input I12 can be used as a remote reset for the horn relay.
