structure of each UPS is shown Figure 6-5 through Figure 6-8 starting 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.
