4.6 Installing UPS External and Battery Power Wiring
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.

4.5 Distributed Bypass Tie Cabinet Installation
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.
The UPS cabinet is shipped with a debris shield covering the ventilation grill on top of
the unit (see Figure 15). Do not remove the debris shield until installation is complete.
However, remove the shield before operating the UPS. Once the debris shield is
removed, do not place objects on the ventilation grill.
Remove the UPS cabinet top or bottom conduit landing plate to drill or punch conduit
holes (see Figure 15).
If the load requires a neutral, a bypass source neutral must be provided.
DO NOT install both a source neutral and a bonding jumper. See
bonding jumper wire sizes. Bonding jumper must be copper wire.
