4.6 Charge the Battery
The UPS charges its battery whenever it is connected to utility power. For best results, charge the
battery for 2.5 hours before use. It is acceptable to use the UPS without first charging the battery,
but on-battery run time may be reduced until the battery charges.
4.7 Connect the Loads
Plug the loads into the output connectors on the rear of the UPS. To use the UPS as a master on/
off switch, make sure that all of the loads are switched on.
Test the system with all loads operating to make sure that the UPS is not overloaded. See section
6.2.
4.8 Connect Ground Leads to TVSS Connector (Optional)
The UPS features a TVSS connector for connecting the ground lead on transient voltage surge-
suppression (TVSS) devices such as telephone and network line protectors. The TVSS connector
provides grounding through the UPS’s power cord ground conductor.
Note: Do not use the TVSS connector without first verifying that the UPS is properly grounded.
To make a connection to the TVSS connector, loosen the screw and connect the surge suppression
device’s ground lead. See section 3.2 for the location of the connector. Tighten the screw to secure
the lead.
