DIN-rail Mounting
1. Snap the controller onto the DIN
rail as shown in the figure to the
right.
2. When properly mounted, the

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 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.
 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 input lines used over an extended distance.
Use wire that is properly sized for the load.
 The controller and I/O signals must be connected to the same 0V signal.
 Connect cable shields to the system earth ground using the shortest and thickest possible wire.
