9 OPERATION RANGEPower SupplyThe applicable voltage range for each unit is given in the following table. The working voltage among the three phases must bebalanced within a 3% deviation from each voltage at the compressor terminals. The starting voltage must be higher than 85% ofthe rated voltage.Power SupplyMODEL Unit Main Power Applicable Voltage MODEL Unit Main Power Applicable VoltageCU- Phase, Volts Hz Max Min CU- Phase, Volts Hz Max MinA24BBP5 1~220 50 242 198 A28BBP8 3N~380 50 418 342A28BBP5 1~230 50 253 207 A34BBP8 3N~400 50 440 360A34BBP5 1~240 50 264 216 A43BBP8 3N~415 50 457 374C24BBP5 A50BBP8C28BBP5 C28BBP8C34BBP5 C34BBP8C43BBP8C50BBP8C28BBP6 1~220 60 242 198 C34BBP7 3~220 60 242 198C43BBP7C50BBP7Indoor and Outdoor Temperature•• Cooling only typeModel 50Hz CU-C24BBP5, CU-C28BBP5, CU-C28BBP8, CU-C34BBP5, CU-C34BBP8, CU-C43BBP8, CU-C50BBP8Model 60Hz CU-C28BBP6, CU-C34BBP7, CU-C43BBP7, CU-C50BBP7Operating Hz Indoor Temp.
