23452 = 5 v457 = 7 v455 = 2 vLEGENDFLA — Full Load AmpsLRA — Locked Rotor AmpsMCA — Minimum Circuit AmpsMOCP — Maximum Overcurrent ProtectionRLA — Rated Load AmpsNOTES:1. In compliance with NEC (National Electrical Code) requirementsfor multimotor and combination load equipment (refer to NECArticles 430 and 440), the overcurrent protective device for theunit shall be Power Supply fuse . The CGA (Canadian GasAssociation) units may be fuse or circuit breaker.2. Minimum wire size is based on 60 C copper wire. If other than60 C wire is used, or if length exceeds wire length in table,determine size from NEC.3. Unbalanced 3-Phase Supply VoltageNever operate a motor where a phase imbalance in supply volt-age is greater than 2%. Use the following formula to determinethe percentage of voltage imbalance.% Voltage imbalancemax voltage deviation from average voltage= 100 x average voltageEXAMPLE: Supply voltage is 460-3-60.AB = 452 vBC = 464 vAC = 455 v452 + 464 + 455Average Voltage = 31371= 3= 457Determine maximum deviation from average voltage.(AB) 457(BC) 464(AC) 457Maximum deviation is 7 v.Determine percent of voltage imbalance.7% Voltage Imbalance = 100 x 457= 1.53%This amount of phase imbalance is satisfactory as it is below themaximum allowable 2%.IMPORTANT: If the supply voltage phase imbalance ismore than 2%, contact your local electric utility companyimmediately.®*Heater capacity (KW) based on heater voltage of 208v, 240v, & 480v.If power distribution voltage to unit varies from rated heater voltage,heater KW will vary accordingly.50JZ WITH ICM FIOP ELECTRICAL DATAUNITSIZE50JZ V-PH-HzVOLTAGERANGE COMPRESSOR OUTDOORFAN MOTOR INDOORFAN MOTOR ELECTRIC HEATSINGLE POINTPOWER SUPPLYMin Max RLA LRA FLA FLA Nominal kw* FLA UNIT MCAMAX FUSEor CKT.
