The 93PM G2 UPS contains a total of five (5) customer input connectors, 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.
There is also one general alarm relay output on the front panel. This output is either normally open (NO) or
normally closed (NC). Polarity selection is made with wiring connection. By default, the general alarm
relay activates when a system alarm is active, that is, any ALARM condition in the system is active.
Alternatively, it can be activated with any particular event but this must be programmed separately by
qualified service personnel. The alarm relay is designed for signal level (ELV or SELV) voltages only, not
for utility use. For higher signaling circuit voltage requirements, please use Industrial Relay Card in
MiniSlot.

These inputs are located behind the UPS door, in the top section of the UPS. See Figure
23: Communication interfaces for the connector locations.
Signal inputs can be configured to different functions. Normally these functions are either informative (for
example, “On Generator”) or functional (for example, a remote “Go to bypass” command).
