. If desired, there is one normally-closed
Auxiliary Contact (A) on the transfer switch to operate
customer accessories, remote advisory lights, or remote
annunciator devices. A suitable power source must be
connected to the common terminal. If needed, an extra
auxiliary contact can be added.
The auxiliary contact is normally closed when the transfer
switch is in utility mode. The contacts will open when the
transfer switch is in the standby power mode.
NOTE: Auxiliary Contact is rated 10 amps at 125 or 250
volts AC, and 0.6 amps at 125 volts DC.
