NOTICE
Risk of improper cable connections. Can cause equipment damage.
Cables between the batteries and the UPS should be run in matched pairs, positive-with-negative, within each conduit or
cable run.
Grouping like-polarity cables together (i.e., positive-with-positive and negative-with-negative) can cause stress or damage
to the cables, conduit or buswork.
2.4.1 Connected System
For cabinets ordered as connected (battery cabinets will bolt to each other), the positive and negative busbars
are connected between battery cabinets with the supplied busbar connector extensions. See
