EXF-RC15 Installation Guide

Wiring

 Do not touch live wires.
 Install an external circuit breaker. Guard against short-circuiting in external wiring.
 Use appropriate circuit protection devices.
 Unused pins should not be connected. Ignoring this directive may damage the device.
 Double-check all wiring before turning on the power supply.
 To avoid damaging the wire, do not exceed 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
Caution
to break.
 Install at maximum distance from high-voltage cables and power equipment.

Wiring Procedure

Use crimp terminals for wiring; use 3.31 mm² –0.13 mm² wire (12-16 AWG):
1. Strip the wire to a length of 7±0.5mm (0.275±0.020").
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.
 Input or output cables should not be run through the same multi-core cable or share the same wire.
 Allow for voltage drop and noise interference with I/O lines used over an extended distance. Use
wire that is properly sized for the load.
 The model and I/O signals must be connected to the same 0V signal.

I/Os

This model comprises a total of 9 digital inputs, 2 relay outputs and 4 npn (sink) outputs. Input
functionality can be adapted as follows:
1. The digital inputs may be wired, in one group, and set to either npn or pnp via wiring.
In addition, according to appropriate wiring:
- Inputs 0, 2, and 4 can function as high-speed counters, as part of a shaft-encoder,
or as normal digital inputs.
- Inputs 1, 3, and 5 can function as either counter reset, as part of a shaft-encoder,
or as normal digital inputs.
- If inputs 0, 2 and 4 are set as high-speed counters (without reset), inputs 1, 3 and 5
can function as normal digital inputs.
