EXTERNAL AUX CONTACT INPUT AND OUTPUT TERMINAL BLOCKS

The UPS is equipped with terminals strips TN1 (Input) and TN2 (Output) on the Auxiliary Connection
Board, IOAU-09. Some of these terminals are user-assignable to a variety of functions. These can be
programmed to:
Inputs (TN1): Control the UPS remotely, or report environmental data to the UPS.
Outputs (TN2): Report status data from the UPS to external annunciation/monitoring devices.
4.4.1

Aux contacts - Input

The Input terminal provides four (IN1 thru IN4) programmable contacts (see) that can be set to any of the
functions in Table 4-1.
PROHIBIT
Inputs require a dry NO (Normally Open) contact to be wired on the corresponding terminals on TN1 of
IOAU-09. Closing this contact activates the selected functionality set for that input. The Inputs provide a
signal or "wetting" voltage of 24VDC / 8.3 mA. See Figure 4-19. The function takes effect immediately upon
contact closure, and is removed immediately upon opening.
