Field Installed Upm (Fi-Upm) Installation; Battery Cabinet Installation; Distributed Bypass Tie Cabinet Installation - Eaton 9395 User And Installation Manual

4.3 Field installed UPM (FI-UPM) installation

If installing a system with Field Upgrade UPM, install the FI-UPM using the instructions in the Eaton
9395 Field Installed UPM Mechanical Installation Manual, listed in section 1.8 on page 10. After the FI-
UPM is installed, proceed to Section 4.4 if installing a battery system; otherwise, proceed to Section
4.5.

4.4 Battery cabinet installation

To install the battery cabinet, refer to the Eaton 9395 Integrated Battery Cabinet (Model IBC-L)
installation manual. 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.
After the battery system is installed, proceed to Section 4.5 if installing a distributed bypass tie cabinet;
otherwise, proceed to Section 4.6 to complete the wiring of the UPS and battery cabinet.

4.5 Distributed bypass tie cabinet installation

NOTE
The tie cabinet must contain Module Output Breakers (MOBs) with dual auxiliary contacts for
control of the system. Without dual auxiliary MOBs, UPSs are not allowed to go to bypass
individually during servicing. All UPSs will go to bypass instead of just the UPS needing service,
decreasing critical load protection. With dual auxiliary MOBs, one UPS can be bypassed while
the remaining UPSs 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. After the tie cabinet is installed, proceed to Section 4.6 to complete the wiring of the
UPS.
