3.0 Installation

3.4 Connecting to the utility

Your PowerCell is furnished with a 6 foot line cord terminated with a standard NEMA 5-15P three pronged plug. The UPS must be plugged into a 2 pole, 3 wire grounding receptacle. If an extension cord must be used between the UPS and the nearest wall outlet, use a 3 wire grounding type rated for at least 10 Amps.

Your PowerCell is provided with a rear SITE WIRING FAULT indicator. Once loads are connected, the indicator illuminates when the UPS is turned on and connected to an outlet whose wiring is improper or inadequate. This could mean that the “hot” and “neutral” wires at the wall receptacle are reversed, the ground wiring is missing, or the “neutral” wiring is overloaded.

Note: If your PowerCell indicates a site wiring fault, a qualified electrician should be summoned to correct the service wiring.

3.5 Battery charging

Your PowerCell is shipped from the factory with its internal battery in a fully charged state. However, the battery may lose some charge during shipping and storage. The battery should be recharged before conducting the following Test for proper operation (section3.7) and to ensure that your PowerCell will provide expected run time. The battery is automatically charged by the UPS whenever the PowerCell is plugged in (the power I/O switch does not have to be on). You can be sure that the battery is fully recharged if the PowerCell is left plugged in for at least 6 hours. Your PowerCell may be used immediately upon receipt, but may not provide expected run time in the event of a utility power failure.
