ARC FLASH AND ELECTRIC SHOCK HAZARD
Arc flash and electric shock hazard. Disconnect all electric power supplies, verify with a voltmeter
that electric power is off and wear protective equipment per 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, verifying that all the parts are included and
check the nameplate to be sure the voltage matches available utility power.
The line side of the disconnect switch contains live high-voltage.
The only way to ensure that there is NO voltage inside the unit is to install and open a remote
disconnect switch and verify that power is off with a volt meter. Refer to unit electrical schematic.
Follow all local codes.
