4.7 Site Wiring Fault Indicator Inspection (where applicable)
After connecting the loads and the UPS, check the site wiring fault indicator on the rear panel. See
section 3 for location of the indicator on the rear panel. It will illuminate if the UPS is connected to
an improperly wired AC power outlet. Wiring faults detected include ground, hot-neutral polarity
reversal, and overloaded neutral circuit.
4.8 Computer Interface Connection (optional)
Power monitoring software and interface kits are included with each UPS. If used, ensure that all
equipment is OFF and connect one end of the interface cable to the 9-pin computer interface port
on the back panel of the UPS and the other end to an unused COM port on the computer. Use only
kits and/or cables supplied or approved by the manufacturer. See section 7 for additional info.
NOTE: The computer interface connection is optional and not necessary for the UPS to function
correctly.
4.9 External Battery Pack Connection (Extended Run-Time Models)
Before connecting, ensure that the external battery pack and connector cable are compatible with
the UPS. Use only the factory supplied, external battery connection cable.
NOTE: The external battery connection is optional and not necessary for the UPS to function correctly.
4.10 Rack Mount Models
Depending on installation, 19" rack-mount applications may require the use of guide rails and/or
brackets to support the weight of the UPS. Please contact the manufacturer of your rack or
enclosure to purchase suitable mounting/installation hardware.
A Note on RFI (Radio Frequency Interference)
There is no guarantee that interference to a radio or TV receiver will not occur in a particular
installation. If the UPS causes interference to radio or television reception, which can be
determined by turning the UPS OFF and ON, the user is encouraged to try to rectify the problem
by trying one or more of following:
• Connect the equipment to an outlet on a circuit different from that to which the receiver is
connected.
• Increase the separation between the equipment and the receiver.
• Re-orient the receiving antenna.
