WARNING
Hazardous Voltage!
Disconnect all electric power,
including remote disconnects before
servicing. Follow proper lockout/
tagout procedures to ensure power
cannot be inadvertently energized.
Failure to disconnect power before
servicing could result in death or
serious injury.
CAUTION
Use Copper Conductors Only!
Unit terminals are not designed to
accept other type conductors. Failure
to use copper conductors may result
in equipment damage.
Notes:
1. Voltage range:
Nominal voltage 208 - 230V - acceptable range: 187 - 253V
Nominal voltage 460V - acceptable range: 414 - 506V
Nominal voltage 575V - acceptable range: 518 - 633V
2. Ampacity is calculated per UL formula, ampacity = (1.25 x compressor RLA + sum of the second compressor RLA (if
used) + evaporator motor FLA
3. Maximum fuse size is calculated per UL formula, MFS = (2.25 x compressor RLA) + sum of second compressor RLA (if
used) + evaporator motor FLA
