SAFETY CONSIDERATIONS
Installing, starting up, and servicing air-conditioning equipment can be hazardous due to system pressures, electrical components, and equipment location.
Only trained, qualified installers and service technicians should install, start up, and service this equipment.
When working on air-conditioning equipment, observe precautions in the literature, on tags, stickers, and labels attached to the equipment.
Follow all safety codes. Wear safety glasses and work gloves. Use care in handling and installing this accessory.
Be sure power to equipment is shut off before performing installation, maintenance or service. Lock out and safety­tag all disconnects. Be aware that there may be more than one disconnect. Serious personal injury from electric shock could result.
GENERAL
This accessory provides required components to integrate control of an external pump into the 30XA chiller control. As part of the chiller control, the pump will be commanded on or off based on the chiller operation. The pump will also be monitored through the chiller control for its status. Any corre­sponding alarms will be reported if the pump does not operate normally.
One accessory package is required for 30XA080-500 units.
INSTALLATION
Examine the package contents for correct part numbers. If any of the components are missing or damaged, file a claim with the shipping company and notify your Carrier representa­tive. See Table 1 for accessory package contents. Refer to Fig. 1-3 for wiring details, and see Fig. 4 and 5 for board mounting locations.
The following material is field-supplied:
• 18 AWG (American Wire Gage) wires for pump control
wiring
• Wire terminals and wire ties

To install the 30XA external pump accessory complete the
following steps.
1. Disconnect unit power.
2. Set the board address switch on the pump board as shown in Fig. 2. Mount the pump board in the main control panel with the No. 8 screws. See Fig. 4 and 5 for the board mounting location.
NOTE: Mounting standoffs are required for 30XA080­120 units, 200/230, 380v and 30XA140-500 units, all voltages.
3. Mount the 24 v circuit breaker (CB14) in the CB14 mounting hole on the display mounting bracket. See Fig. 4 and 5 for the mounting hole location. The display mounting bracket can be easily removed by loosening the four mounting screws on the corners.
4. Connect the 24 v power from TB10-X1 (30XA080-120 units, 460/575 v only) or TB11-X1 (all other units and voltages) to CB14 with a red wire in the harness assembly (Item 2). Find a 2-pin plug marked J1-11,12 with a red wire and a brown wire in the harness assembly. Connect the plug to the pump board J1. On the other end, connect the red wire from the plug to CB14 and the brown wire to TB10-X2 (30XA080-120 units, 460/575 v only) or TB11-X2 (all other units and voltages). Refer to Fig. 1.
5. Connect TB5-11, 13 to pump board CH1 and TB5-13, 15 to pump board CH2 per Fig. 2 with the harness assembly provided (Item 2). Use the pins on the back of TB5.
NOTE: If only one pump is available in the system (no backup pump), the wiring for pump board CH2 is not required.
6. For 30XA080-120, 200/230 v, 380 v and all 30XA140-500 units, disconnect the 3-pin plug on MBB (main base board) J9B (or EMM board J9A) for communication and plug it in to the pump board J9. Use the communication cable assem­bly (Item 6) to connect between pump board J9 and MBB J9B (or EMM board J9A when EMM board exists). The communication cable in the TH70400864 harness will not be used. For 30XA080-120, 460 v, and 575 v units, connect the 3-pin plug of the communication cable in the harness assembly (Item 2) to the pump board J9 and splice the other end of the cable to the communication network using the wire nuts provided (Item 7). Be sure to splice the wires with the same color together to ensure correct polarity.

7. Wire the coils of pump contactors (PMP1-A1, A2 and PMP2-A1, A2) to TB5-11 and 13 (pump 1) and TB5-13 and 15 (pump 2) as shown in Fig. 2 with field-supplied 18 AWG wires and wire terminals.
NOTE: If only one pump is available in the system (no backup pump), the wiring for PMP2 is not required.
8. Locate the main base board in the main control panel. Refer to Fig. 3. Near CH18 (J5C) of the board, there are violet and pink wires tied up outside the wire duct termi­nated with wire nuts. These wires are for pump auxiliary contact wiring. Remove the wire nuts and connect the two wires to the pump auxiliary contacts per Fig. 3 with field­supplied wiring. Some units may not be supplied with the J5C connector and the violet and pink wires. A 2-pin con­nector (Item 8) is supplied if these parts are not present. Wire the pump contactor auxiliary contacts to the 2-pin connector. Insert the 2-pin connector into MBB-J5C.
NOTE: If only one pump is available in the system (no backup pump), the wiring for PMP-2 is not required.

Test Pump Control Output — Use the Navigator or
Touch Pilot display, the instructions given in the Controls, Start-Up, Operation Service and Troubleshooting manual and the Service Test mode to verify proper operation of pump output. Be sure to turn off the fuse or circuit breaker for the pump(s) and verify that the pump contactor(s) is being energized during the test. For the Navigator display, illuminate the Service Test LED, enter the TEST mode, enable the test request, (‘T.REQ’) and test outputs (‘PMP.1’, ‘PMP.2’). For the Touch Pilot display, from the main menu, follow the
