Mounting the Optional PS-60W AC Power Supply
The optional PS-60W AC power supply can be mounted on the DIN rail, conveniently on the left side of the
Controller. To reduce issues associated with noisy DC power input, keep the 24VDC wiring away from any
AC interfering sources such as motor leads or other devices. Refer to the PS-60W or the user-supplied
power supply for information regarding topics such as mounting, AC power connections, or ratings.
Add I/O wiring to the PACIO Modules
All PACIO Modules require either input power wiring or field I/O wiring. The following section describes the
general wiring guidelines for the Modules.
Power circuits are conductors carrying high voltages, motor leads, or any other high potential switching
circuits. Control circuits are considered to be low voltage digital or analog signals, communication or data
signals, fieldbus or network wiring, or similar.
Keep the following power circuits separate from control circuits:

DC voltages 60 V to 400 V

AC voltages 25 V to 400 V
The following control circuits can be combined:

Shielded data or communication signals

Shielded analog signals

Unshielded digital I/O lines

Unshielded DC voltages < 60 V

Unshielded AC voltages < 25 V
The following wire sizes are recommended for the PACIO Module field and power wiring:

0.20 - 1.0 mm² (IEC) / 26 16 AWG (UL), stripped to <10mm in length, solid or stranded wire

Rated current: 5 A (CSA) / 10 A (UL)

For convenience, the PACIO Module connectors can be prewired and then plugged into the
module. The Module connectors also facilitate easy replacement of a Module with requiring
removal of the individual field wires.
How to attach the wires to the tension clamp terminals:
1. Push a small screwdriver (tip size 0.04mm x 2.5mm) into the small square opening on the back of
the connector.
2. Insert the stripped wire (<10mm) into the adjacent rectangular opening on the connector.
3. Remove the screwdriver.
4. Gently tug on the wire to confirm that it is tightly captured.
