6-2 Internal Battery Connection Procedure (continued)

•11 Use a voltmeter (user-supplied) to test the voltage of each internal battery pack. Observing proper polarity, connect the voltmeter’s black probe to the battery pack’s black connector; connect the voltmeter’s red probe to the battery pack’s red connector. Make sure the voltmeter’s probes touch the metal contacts inside the battery pack’s connectors. The battery pack’s acceptable DC voltage range is between 220V and 280V DC (nominal 240V DC). If several voltmeter tests yield results outside the acceptable DC voltage range, contact Tripp Lite for assistance in determining the possible causes of the incorrect voltage reading before proceeding.

•12 Connect the black cable for each internal battery pack to the nearest black connector located inside the UPS system’s battery compartment. Connect the red cable for each internal battery pack to the nearest red connector located inside the UPS system’s battery compartment. Warning: Observe proper polarity by connecting negative to negative (black to black) and positive to positive (red to red). Failure to observe proper polarity will damage the UPS system and create a serious risk of personal injury and property damage.
