NOTE This oneline does not show each UPM in the UPSs, but represents each UPS in the distributed bypass system. The internal

AC Output to

Critical Load

structure of each UPS is shown Figure 6-5through Figure 6-8starting on page 6−7.

 

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.
