Internal Battery Replacement

When installing the new replacement batteries, make sure the
red and black DC connector end is facing towards the rear of
the UPS and the communication port is facing toward the front
of the UPS. Starting with the right side replacement battery pack
tray, insert the battery pack tray completely into the unit, making
sure it protrudes slightly from the UPS. Repeat for the left
replacement battery pack tray.
Note: For better connector access, attach the communication cable
connectors before the battery packs are fully inserted into the UPS.
