NOTE  This oneline does not show each UPM in the UPSs, but represents each UPS in the distributed bypass system. The internal
structure of each UPS is shown Figure 6-5 through Figure 6-8 starting on page 6−8.
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 neutral to ground bonding jumper must be installed. DO NOT install both a source neutral and a bonding jumper.
