4.5Voltage Requirements

All XDF systems require two input power circuits. Each power cord is 10 feet (3m) long. For the full load amp requirements of each option, refer to 12.1 - Optional Power Systems or the component’s user manual.

4.5.1Voltage Input Requirements

The first input connection provides power—120V-1ph-60Hz, line-to-neutral—to the controls, evapora- tor fans and condenser fan. This input’s power cord has a NEMA 5-15P plug. This power cord should be connected to a UPS-protected power source.

The second input connection on 60Hz XDF units provides power—208V-3ph-60Hz, with neutral—to the compressor, optional condensate pump and an alternate connection for the condenser fan. (The alternate connection for the condenser fan permits reducing the load on the UPS-protected power source.) The 208V power cord has a NEMA L21-30P locking plug.

Changing Condenser Fan Power Source—Self-Contained, Air Cooled Units

! WARNING

Risk of electric shock. Can cause death or injury.

Disconnect all local and remote electric power before working within and/or installing equipment.

To change the power source connections:

1.Open the front door panel and look for two screws with Torx heads that secure the hinged corner panel. The Torx-head screws are on the front doorjamb.

2.Extract the two screws and swing the panel open.

3.Remove the protective covering over the electrical connections (see Figure 18). The cover is secured with two screws.

4.Find the connectors (see Figure 18) and pull apart the snap connection made at the factory.

5.Connect the alternate power source connector to the supply that feeds the condenser fan.

6.Reinstall the protective cover over the electrical connections.

7.Close the outer panel and reinsert the two Torx screws.

8.Close the front door.
