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
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.
