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

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 the
just 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 Installing UPS External and Battery Power Wiring to complete the wiring of the UPS.
In the case of parallel Distributed Bypass configurations, wiring for the common system neutral reference will
also be connected to E12 of each module and this common system neutral reference wiring will be routed to
the output switchgear cabinet and connected to an isolated / ungrounded bus which is common with the wiring
from the E12 terminal of all other paralleled modules of the Distributed Bypass system.
