system manufacturer's instructions and all applicable codes and regulations, including the NEC, Article 480.

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 4.8 to complete the wiring
of the UPS.
