6 – Internal Battery Connection
(continued)
6-2 Internal Battery Connection Procedure
(continued)
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.
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.
Replace the battery access bezels.
•
Follow the proper procedure to restart the UPS and re-transfer the
•
critical load to protected power.
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.
