Replacing the UPS Batteries
1. Connect the UPS Battery Cable to the Power Supply.
2. Insert the batteries in the bracket. This is a tight fit so be careful to
not cut the battery cables. Note the battery orientation. Also, make
sure the one battery is not sitting on top of the vertical sheet metal
extension in the base.
