Read and understand the following notes while planning and performing the
installation:
S
All distributed bypass UPS rectifier inputs must come from one source and all
bypass input feeds must come from one source.
S
All UPSs in the distributed bypass system must contain the same number of
UPMs. Mixed UPS kVA ratings are not permitted.
S
Distributed bypass UPS input wiring size requirements and output wiring size
requirements from the UPSs to the tie cabinet or distribution panel are the same as
listed in Table 3‐4 and Table 3‐5.
S
The Eaton 9395P 480V unit is designed for operation on a ground wire source of
supply. There is no additional connection point for a neutral conductor. The output
of this UPS will not directly support phase to neutral loads.
S
MOBs with dual auxiliary contacts are to be provided by the customer. Table 3‐12
lists the recommended rating for the MOBs.
The tie cabinet is provided by the customer and 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 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.

To prevent damage to the wiring channel and wiring in the UPM section base when lifting or moving the
cabinet:
S
Lift and move the UPM section using only the front or rear forklift slots.
S
Verify that the forklift forks are in a horizontal position before inserting them into the forklift slots.
DO NOT angle fork tips upward.
S
Insert the forks all the way through the base. DO NOT insert forks partially into the base to move the
cabinet.
S
Forks may be partially inserted into the front or rear forklift slots for minor positioning if the forks are
kept in a horizontal position with no upward angling.
S
DO NOT use the forklift slots on the end of the cabinet to move the cabinet.
S
End forklift slots may be used for minor positioning if the forks are kept in a horizontal position with no
upward angling.
