Battery System Installation
If installing a battery system, install the customer-supplied battery system according
to the battery and battery system manufacturer's instructions and all applicable codes
and regulations, including the NEC, Article 480. After the battery system is installed,
proceed to paragraph 4.5 if installing a distributed bypass tie cabinet; otherwise,
proceed to paragraph 4.6 to complete the wiring of the UPS.

Distributed Bypass Tie Cabinet Installation
NOTE
The tie cabinet must contain Module Output Breakers (MOBs) with dual auxiliary contacts for control
of the system. Without dual auxiliary MOBs, UPMs are not allowed to go to bypass individually during
servicing. All UPMs will go to bypass instead of only the UPM needing service, decreasing critical load
protection. With dual auxiliary MOBs, one UPM can be bypassed while the remaining UPMs support the load
as long as the remaining UPMs have the capacity to do so.
If installing a distributed bypass system, install the customer-supplied tie cabinet or
distribution panel according to the tie cabinet or distribution panel manufacturer's
instructions and all applicable codes and regulations, including the NEC, Article 480.
After the tie cabinet is installed, proceed to paragraph 4.6 to complete the wiring of
the UPS.
