Programmable Signal Inputs

The UPS incorporates four programmable signal inputs: one RS-232 input, two connectivity card inputs, and one REPO terminal input. See Figure 18 on page 53 for the locations of the ports. Configure the inputs with the “Signal Inputs” setting in “User Settings” on page 40.

Table 6 shows the programmable settings for the signal inputs. Table 7 shows the operation logic for the signal inputs.

Table 6. Programmable Signal Inputs

Signal	Description
Not Used	The input operates only as a serial input (RxD) or has no function.
Force Bypass	If active, the UPS is forced to static bypass operation regardless of
	the bypass status.
Remote Shutdown	If active, the UPS output turns off after a user-defined remote
	shutdown delay. The batteries continue charging. Inactive input
	does not abort the shutdown countdown and does not cause the
	UPS to start up automatically.
Delayed	If active, the UPS output turns off after a user-defined delayed
Shutdown	shutdown delay. The batteries continue charging. Inactive input
(and restart)	does not abort the shutdown countdown but will cause the UPS to
	start up automatically if the input voltage exists.
On Generator	If active, synchronization is disabled and the UPS transfers to
	bypass.
Building Alarm 1	If active, the UPS generates the “Building Alarm 1” alarm.

Table 7. Polarity Options

Input	Description
High	Active state on high voltage (+Udc) level
Low	Active state on low voltage (GND or -Udc) level
