Two control power sources can be wired to the junc-

secondary source can be connected to either ac control
power or dc substation battery power.
The external power supply can be installed on
IntelliRupter fault interrupters that also have one or two
integrated power modules. The external power supply is
used when power is not supplied by the integrated power
module(s).
