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.
Wiring Guidelines
In order to ensure that the device will operate properly and to avoid electromagnetic
interference:
Use a metal cabinet. Make sure the cabinet and its doors are properly earthed.
Use wires that are properly sized for the load.
Connect the 0V point of the UAG-XKPxxx directly to the power supply 0V terminal.
Connect the functional ground point ( ) to the earth of the system (preferably to the
metal cabinet chassis).
Use the shortest and thickest wires possible: less than 1m (3.3’) in length, minimum
thickness 14 AWG (2 mm2).
Connect the power supply 0V to the earth of the system.

Wiring the Power Supply (UAG-XKPxxx)
The UAG-XKPxxx requires an external 12 or 24VDC power supply.
The 0V of the UAG-XKPxxx end unit must be connected to the HMI Panel’s 0V.
Ignoring this directive may damage the device.
In the event of voltage fluctuations or non-conformity to voltage power supply
specifications, connect the device to a regulated power supply.
Connect the +V and 0V terminals as shown in the
accompanying figure.

Removing the Expansion Cable
1.
Turn off the system power.
2.
Unplug the cable from the Base Unit.
3.
To remove the Base unit, pull the top clip up and the bottom clip down; and pull it
slowly away until the plug disengages.
4.
To remove the End unit:
•
Locate the Bus connector lock of the Uni-I/O™ module connected to the End Unit
and slide it to the right.
