WARNING:

 Arc flash and 

electric shock hazard. Open all 

local and remote electric power-

supply disconnect switches, verify 

with a voltmeter that power is off 

and wear appropriate OSHA-

approved personal protective 

equipment per NFPA 70E before 

working within the electric control 

enclosure. Installer must provide a 

remote, electric-power disconnect 

switch and earth ground to unit per 

NEC, CEC and local codes as 

applicable. Failure to comply can 

cause injury or death.

Hazardous-voltage 

Power-supply Wiring

Wire per NEC and local codes.
Hazardous-voltage electrical 

service is required at the location 

of the control enclosure. Use the 

knockouts provided at the bottom 

of the enclosure. This power 

supply does not have to be the 

same voltage as the Liebert indoor 

unit. This separate power source 

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

2

for up to 75 ft (22.9 m), or not 

to exceed 1-V drop in the 

control line.
