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.
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 corre-
sponding 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 representa-
tive. 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
Table 1 — Accessory Package Contents
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 30XA080-
120 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 assem-
bly (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.
Be sure power to equipment is shut off before performing
installation, maintenance or service. Lock out and safety-
tag all disconnects. Be aware that there may be more than
one disconnect. Serious personal injury from electric shock
could result.
