PM3398B613EPOWER SUPPLYINPUT: 100-240 VAC / 50/60 HZ / 23 AMPOUTPUT: 56 VDC / 26.8 AMP1500.8 WATT OUTPUT POWERThere can be up to 4 AC/DC power supplies in a drive,designated 1, 2, 3 and 4. Each power supply has its ownsensing circuit and will monitor its DC output voltage. • Verify that the power supply is energized and is using the appropriate input control power.• Measure the output voltage and confirm whether the output level is below the trip level.• Verify that the fault detection wiring is per the drawings, and measure the voltage on thetrip signals. For example, Terminal J18 2-3 is 5Vdc when healthy, and 0V in a faulted state.• Verify that the power supply internal cooling fan is operational, cycle control power ifneeded.• If the cooling fan is not operational, replace the power supply.• Check parameter 121 in the Metering group of the drive variables to view the measuredDC voltage.
