3-17
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 3-5 or
Table 3-7).
Terminals E1A through E5A and E9A through E12A are stud type terminals. The intercabinet power wiring
connections for this equipment are rated at 90ºC. See Table 3-10 for external power cable terminations,
Table 3-11 for supplied external wiring terminal hardware.
The torque values listed in Table 3-10 for the M8 studs are the maximum allowable. Tightening further will risk
breaking or twisting the stud.
Figure 4-13 and Figure 4-15 show the location of the power cable terminals inside the UPS.
