NFPA 70E before working within electric control enclosure. Failure to comply can cause
serious injury or death.
Customer must provide earth ground to unit, per NEC, CEC and local codes, as applicable.
Before proceeding with installation, read all instructions, verify that all the parts are included
and check the nameplate to be sure the voltage matches available utility power.
The Liebert iCOM microprocessor does not isolate power from the unit, even in the Unit Off
mode. Some internal components require and receive power even during the Unit Off mode of
Liebert iCOM control.
The line side of the disconnect switch on the front of the unit contains live high-voltage.
The only way to ensure that there is NO voltage inside the unit is to install and open a remote
