4.32 Hardwired models
The terminal block is used to “hardwire” the UPS, thus allowing connection of input/output wiring. Use
#8 AWG wire (Twisted wire cable) for possible 3/4” conduit use and terminate each wire with appropriate
size/rating terminal lugs. Input/Output wires should be secured with terminal block screws using
29 ft.-lbs. of torque.
4.4 Battery Charging
The UPS charges its battery whenever it is connected to utility power. For optimum results, charge
the battery for at least 8 hours prior to initial use.
4.5 Load Connection
Connect the load(s) to the output receptacles or hardwire terminal block (per 4.32) on the rear of the
UPS. To use the UPS as a master ON/OFF switch, make sure all of the loads are switched ON.
CAUTION: Do NOT connect a laser printer or plotter to the UPS with other computer equipment. A laser
printer or plotter periodically draws significantly more power than when idle, and may overload the UPS.
4.6 Computer Interface Connection (Optional)
UPS control and power monitoring software kits are included with each UPS. If used, ensure that all
equipment is OFF and connect one end of the interface cable to the 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
4.7 External Battery Pack Connection (Optional)
Before connecting, ensure that the external bettery pack and connector cable are compatible with the UPS.
The DC bus voltages must be the same. 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.
4.8 Rack Mount Units
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. Please see the installation diagrams that follow for guidance.
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 turining the
UPS OFF and ON, the problem may be rectified by trying one on more of the 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.
