9395 550/275 UPS (225–550 kVA) Installation and Operation Manual 164201716—Rev 8 www.eaton.com/powerquality 3-13
AC input to the UPS with separate rectifier inputs is wired as if each UPM is rated for 275 kVA (see
Table 3-8).The bypass input, battery input, and output are wired the same as for a separate battery UPS (see
Table 3-6).
For a UPS with common rectifier input terminals, E1 through E12 are 2-hole bus bar mountings for standard
NEMA 2-hole barrel lugs. The power wiring connections for this equipment are rated at 90ºC. See Table 3-12
for external power cable terminations, Table 3-11 for supplied external wiring terminal hardware, and Table 3-12
for recommended installation parts and tools not supplied by Eaton Corporation.
For a UPS with separate rectifier input terminals for the UPMs, E1 through E3 are pressure terminations, UL
and CSA rated at 90ºC. See Table 3-13 for power cable terminations.
Figure 4-5 and Figure 4-5 show the location of the power cable terminals inside the UPS.
