Power Xpert 9395 UPS (450–550 kVA) Installation and Operation Manual
If installing a Plus 1 model, install the FI-UPM using the instructions in the Power
Xpert 9395 Field Installed UPM Mechanical Installation Manual, listed in paragraph 1.8
on page 1-10. After the FI-UPM is installed, proceed to paragraph 4.4 if installing a
battery system; otherwise, proceed to paragraph 4.5.
If installing an Eaton battery cabinet, refer to the Power Xpert 9395 Integrated Battery
Cabinet (Model IBC-L) Installation Manual, listed in paragraph 1.8 on page 1-10.
If installing a customer-supplied battery system, install the 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.
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.
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.
