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.
NOTE The UPS cabinet is shipped with debris shields covering the ventilation grills on top of the cabinet.
Do not remove the debris shields until installation is complete. However, remove the shields before operating
the UPS. Once the debris shields are removed, do not place objects on the ventilation grills.
NOTE Remove the UPS cabinet top or bottom conduit landing plate to drill or punch conduit holes (see
Figure 4‐4 on page 4-8).
NOTE If the load requires a neutral, a bypass source neutral must be provided.
NOTE DO NOT install both a source neutral and a bonding jumper. See Table 3‐7 on page 3-11 for neutral
bonding jumper wire sizes. Bonding jumper must be copper wire.
HIGH IMPEDANCE GROUND SOURCES - If the supply source is a high impedance ground (IT) type, the input
neutral conductor must be connected from the source of supply. If there is no output neutral connected to the
UPS, the neutral‐forming transformer kit may be used instead of pulling a neutral from the source. If the load
requires a neutral, then an input neutral conductor must be pulled into the UPS. In no circumstances shall a
neutral to ground bonding jumper be installed in the UPS.
