Figure E: Single AC Source
The configuration shown in
Figure E
details the connections when the UPS is fed by a
single AC source. In this configuration the rectifier, bypass and maintenance bypass lines
are all fed by the same source.
Connect your utility input wires to the Utility Input terminals (marked L1 and L2) on the far
left of the terminal rail. Note that the second set of terminal blocks is not used in this
configuration.
