NOTE
1. SINGLE-SOURCE FEED—If feeding the Maintenance Bypass Cabinet from a single 
source, the input connection may be made to either TB1 or TB2.
2. DUAL-SOURCE FEED—If feeding the Maintenance Bypass Cabinet from a dual source, 
the UPS input supply connection must be made to TB1 and the bypass input supply 
connection must be made to TB2. The jumpers between TB1 and TB2 must be removed.
3. If connected equipment is a combination of 208 VAC and 120 VAC, use a three-phase panel 
board connected to the output terminal TB5.
