The 93PM G2 UPS contains a total of five (5) signal input connectors for
customers which can be used for giving remote control commands to the UPS.
Customer interface connector TB1 can be used for these purposes. Each input is
a dry relay contact input and requires two wire signaling. None of the inputs are
pre-programmed but need to be separately programmed by qualified service
personnel.
NOTE: When using an external battery system, Eaton recommends you to
connect external signal wiring.
