4.1 Installing and Removing Internal Batteries (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
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.
• Connect the black cable for each internal battery pack to the
12
nearest black connector located inside the UPS system's battery
compartment. Connect the
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.
• 13 Replace the battery access bezels.
• 14 Turn on the internal battery circuit breaker switch. If you placed
the UPS system in bypass, return it to the previous operating mode.
If you turned the UPS system off, turn it on.
Note: If you need to remove or replace internal battery packs, modify
steps 6 and 7 by removing and/or replacing the existing internal battery
packs, as required.
