electrical shock, personal injury, or damage to the controller.

UC Open XP installation
8 UC Open XP/UC Open XP IO
To install the UC Open XP:
1 Mount the controller. (page 9)
2 Wire the controller for power. (page 10)
3 Set the controller's address. (page 10)
4 Wire expanders to the controller. (page 18)
5 Wire inputs and outputs (page 13).
6 Wire sensors to the controller. (page 23)
To install the UC Open XP into an i-Vu Open Control System
You must complete the following procedures to successfully install your UC Open XP into an i-Vu Open Control
System. Use the Help in the referenced software for detailed descriptions of these procedures.
ApplicationBuilder or Snap
1 Use ApplicationBuilder or Snap to create control program(s) for your UC Open XP.
2 If applicable, print the Sequence of Operation created by ApplicationBuilder, which includes the points
list.
NOTE You can create a points list under Reports in Field Assistant after installing your control program.
UC Open XP Installation Guide
1 Prepare a wire list using the points list. Refer to the Appendix (page 29).
2 Use the wire list and the following installation procedures to install and wire I/O points to your UC Open
XP and expander, if applicable.
i-Vu/Field Assistant

2 In Discovery > Setup, select Add Control Program, upload control program and graphic to i-Vu/FA, then
download to the controller.
3 Select the controller in the navigation tree and go to Properties page > I/O Points tab to assign channel
numbers to the physical points.
NOTE 39m AHU Equipment has pre-assigned IO channels. See Appendix B (page 33). You must assign
IO channels in all other applications by:
○Entering your channel numbers under Num, using your wire list
○Entering your expander address under Exp, if applicable
○Selecting the appropriate value under Sensor/Actuator Type, if applicable

4 Open the Properties page > Equipment tab to configure the controller. Each configuration parameter on
the Properties page > Equipment tab is explained in detail under the corresponding section. For
additional information on the operation of the equipment, consult the Sequence of Operation, which is
created in ApplicationBuilder, and the relevant Installation and Start-up Guide.
5 Check out and commission the equipment.
To mount the UC Open XP
When you handle the UC Open XP:
•Do not contaminate the printed circuit board with fingerprints, moisture, or any foreign material.
•Do not touch components or leads.
•Handle the board by its edges.
•Isolate from high voltage or electrostatic discharge.
•Ensure that you are properly grounded.
Screw the UC Open XP into an enclosed panel using the mounting slots on the cover plate. Leave about 2 in.
(5 cm) on each side of the controller for wiring.
Mounting hole dimensions 4" (width) by 11.4" (height).

UC Open XP installation
10 UC Open XP/UC Open XP IO
Wiring the UC Open XP for power
The UC Open XP is powered by a Class 2 power source. Take appropriate isolation measures when
mounting it in a control panel where non-Class 2 circuits are present.
Carrier controllers can share a power supply as long as you:
• Maintain the same polarity
• Use the power supply only for Carrier Open controllers
To wire for power
1 Turn off the UC Open XP's power switch to prevent it from powering up before you can verify the correct
voltage.
2 Remove primary power from the 24 Vac transformer.
3 Pull the screw terminal connector from the controller's power terminals labeled Gnd and 24 Vac.
4 Connect the transformer wires to the screw terminal connector.
5 Apply primary power to the transformer.
6 Measure the voltage at the UC Open XP's power screw terminal connector to verify that the voltage is
within the operating range of 21.6 - 26.4 Vac.
7 Insert the screw terminal connector into the UC Open XP's power terminals.
8 Turn on the UC Open XP's power switch.
9 Verify that the Power LED is on and the Run LED is blinking.
To set the UC Open XP's address
The UC Open XP's two rotary switches determine the UC Open XP's MAC address when it is placed on a
BACnet MS/TP network. The rotary switches define the MAC address portion of the device's BACnet address,
which is composed of the network address and the MAC address.
1 Turn off the UC Open XP's power switch.
2 Using the rotary switches, set the controller's address. Set the Tens (10's) switch to the tens digit of the
address, and set the Ones (1's) switch to the ones digit.

UC Open XP/UC Open XP IO 11
EXAMPLE If the controller’s address is 25, point the arrow on the Tens (10's) switch to 2 and the arrow
on the Ones (1's) switch to 5.

3 Turn on the UC Open XP's power switch. The controller reads the address each time you apply power to it.
NOTE The factory default setting is "00" and must be changed to successfully install your UC Open XP.
Wiring the UC Open XP to the MS/TP network
The UC Open XP communicates using BACnet on an MS/TP network segment communications at 9600 bps,
19.2 kbps, 38.4 kbps, or 76.8 kbps.
Wire the controllers on an MS/TP network segment in a daisy-chain configuration.
Install a BT485 on the first and last controller on a network segment to add bias and prevent signal
distortions due to echoing.
See the MS/TP Networking and Wiring Installation Guide for more details.
Wiring specifications
Cable: 22 AWG or 24 AWG, low-capacitance, twisted, stranded, shielded copper wire
Maximum length: 2000 feet (610 meters)

UC Open XP installation
12 UC Open XP/UC Open XP IO
To wire the controller to the network
1 Pull the screw terminal connector from the controller's power terminals labeled Gnd and 24 Vac or Hot.
2 Check the communications wiring for shorts and grounds.
3 Connect the communications wiring to the BACnet port’s screw terminals labeled Net +, Net -, and
Shield.
NOTE Use the same polarity throughout the network segment.
4 Verify that the MSTP jumper is set to MSTP.
5 Set DIP switches 1 and 2 to the appropriate baud rate. See the MSTP baud diagram on the UC Open XP.
The default baud rate is 76.8 kbps.
NOTE Use the same baud rate for all controllers on the network segment.
6 Set DIP switches 3 and 4 for MSTP.
7 Verify the jumper is set on the right 2 pins.
8 Verify that the Communications Selection jumper is set to EIA-485.
9 Insert the power screw terminal connector into the UC Open XP's power terminals.
10 Verify communication with the network by viewing a module status report.

UC Open XP installation
14 UC Open XP/UC Open XP IO
Binary outputs
The UC Open XP has 6 binary outputs. Each output is a dry contact that must be powered from a Class 2
power source.
To size output wiring, consider the following:
•Total loop distance from the power supply to the controller, and then to the controlled device
NOTE Include the total distance of actual wire. For 2-conductor wires, this is twice the cable length.
•Acceptable voltage drop in the wire from the controller to the controlled device
•Resistance (Ohms) of the chosen wire gauge
•Maximum current (Amps) the controlled device requires to operate
Analog outputs
The UC Open XP has 6 analog outputs that support voltage or current devices. The controlled device must
share the same ground as the UC Open XP and have the following input impedance:
0–10 Vdc
0–20 mA
min 500 Ohms
max 800 Ohms
To wire inputs and outputs on the UC Open XP
1 Turn off the UC Open XP's power.
2 Connect the input wiring to the screw terminals on the UC Open XP.

NOTES
○If using shielded wire, connect the shield to the GND terminal with the ground wire. Tape off the
shield wire at the sensor end.
○Connect the shield wire to the GND terminal with the ground wire.
○Use only UI-1 or UI-2 for pulse counter or timed local override.
○For an internally-powered 4-20 mA sensor, wire the sensor's positive terminal to the +terminal on
the UC Open XP's Aux Power Out port. Wire the sensor's negative terminal to an input's +terminal.
