Operation
Set-Up
The recommended procedure for setting up the UPS is the following:
• Insert the BATTERY PACK (if not already present) and tighten its screws.
• Make sure the AC BREAKER 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 DC OUTPUT cable is connected to the UPS and the load with the correct polarity.
• Connect the USER I/O cables.
• Connect all INPUT cables, first to the UPS and then to the various sources.
• 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 DC INPUT cable is connected to the UPS and the source of DC power with the
correct polarity.
• Turn on the sources (if they have an upstream breaker).
• Move the AC BREAKER 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 present a hazardous voltage at its output.
