Vertiv™ Liebert® MCV condenser power connections are provided for three phase wires and one earth ground wire. Line
voltage electrical service is required for all condensers at the location of the condenser. The voltage supply to the condenser
may not be the same voltage supply as required by the indoor unit. Consider using a UPS on both indoor cooling units and
Liebert® MCV condensers to maintain uninterrupted cooling capability. Refer to the unit’s serial tag for specific condenser
electrical requirements. A unit disconnect is standard. However, a site disconnect may be required by local code to isolate the
unit for maintenance. Route the supply power to the site disconnect switch and then to the unit. Route the conduit to the
knockout provided in the bottom right end of the electrical control enclosure. Connect the earth ground wire lead to the
marked earth ground connection terminal provided near the factory installed disconnect switch per the appropriate drawing
in the Submittal Drawings.
NOTE: A separate neutral wire does not need to be run to the Liebert® MCV Condenser.
