Power-supply Wiring
Wire per NEC and local codes.
Hazardous-voltage electrical
service is required at the location

knockouts provided at the bottom
of the enclosure. This power
supply does not have to be the
same voltage as the Liebert indoor

may be 110V, 208V, 230V, 460V or
575V, single-phase or three-phase,
60Hz; or it may be 200V, 230V,
380V or 415V, single-phase or
three-phase, 50 Hz as appropriate.
Extra-low-voltage Control
Wiring
Control interlock between the
control enclosure and the indoor
unit(s) or other source(s) is
required. Multiple indoor units may
be connected in parallel if the
controlled pumps will feed them all.
• Extra-low voltage, non-safety
control wiring must be a
minimum of 16 GA. (1.665 mm

)
for up to 75 ft (22.9 m), or not
to exceed 1-V drop in the
