User’s and Installation Guide Revision E
6.5 Multiple UPS distributed bypass system oneline
configurations
The distributed bypass system oneline drawings in this section show the simplified internal structure of
the UPS, battery supply, and basic maintenance bypass in a multiple UPS configuration. These onelines
do not show each UPM in the UPSs, but represent each UPS in the distributed bypass system. The
internal structure of each UPS is shown in Figure 6-6 through Figure 6-9 starting on page 61.
NOTE
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 UPS neutral
must be connected to source star point.
