If installing a Plus 1 model or adding the FI-UPM to an 825/550 model, install the FI-UPM using the instructions
in the Power Xpert 9395 Field Installed UPM Mechanical Installation Manual, listed in paragraph
1.7 For More Information. After the FI-UPM is installed, proceed to paragraph 4.6 Battery System Installation if
installing a battery system; otherwise, proceed to paragraph 4.7 Distributed Bypass Tie Cabinet Installation.

If installing a battery system, install the customer-supplied 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 4.7 Distributed Bypass Tie Cabinet Installation if
installing a distributed bypass tie cabinet; otherwise, proceed to paragraph
4.8 Installing UPS External and Battery Power Wiring.

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
4.6 Battery System Installation 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.

NOTE 1 The ISBM and UPM sections are shipped with debris shields covering the ventilation
grills on top of the sections (see Figure 39). 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 2 Remove the ISBM section top or bottom conduit landing plate to drill or punch conduit
holes (see Figure 40).
NOTE 3 If the load requires a neutral, a bypass source neutral must be provided. If the load does
not require a neutral and there is no neutral conductor connected at the bypass input, a
neutral to ground bonding jumper must be installed. DO NOT install both a source
neutral and a bonding jumper. See Table 5 through Table 8 for neutral bonding jumper
wire sizes. Bonding jumper must be copper wire.
