Operation
Set-Up
The following are the recommended installation steps for the 3-Phase UPS-1500 series:
• Insert the BATTERY PACK (if not already present) and tighten its screws.
• Make sure the AC SWITCH on the rear panel of the UPS is in the “OFF” position.
• Connect the ground wire to the ground stud on the rear panel of the UPS.
• Connect all OUTPUT cables, first to the UPS and then to the various loads.
• VERIFY that the optional DC OUTPUT cable is connected to the UPS and the load is connected
with the correct polarity.
• Connect the USER I/O cables.
• Connect the 3-Phase INPUT AC cables, first to the UPS and then to the source.
• Connect the DC INPUT cables (if the option is available), first to the UPS and then to the source.
• An overcurrent protect and disconnect device should be installed on the DC INPUT circuit.
An example of a suitable device is a Carling Technologies, C-series, 80 A 65 VDC, CA1-B0-14-
680-321-J circuit breaker. (www.carlingtech.com)
• VERIFY that the optional DC INPUT cable is connected to the UPS and the source of DC
power with the correct polarity.
• Turn “ON” both the AC and DC (if present) sources.
• Move the AC SWITCH on the rear panel of the UPS to the “ON” position.
Note: Be careful to not toggle the “ON/OFF” switch during the setup. Doing so could cause the
UPS to turn “ON” and have a hazardous voltage at the output.
