Relay Signal Description
UPS ok Activated when the UPS is feeding the load on inverter or on bypass and no
alarms are active
On Bypass Activated when the UPS is NOT on bypass operation
On Battery Activated when the UPS operates on battery and the "On Battery Notice
Delay" time has expired
Battery Low Activated with the "Battery Low" alarm according to the "Battery Low Alarm"
setting
Ext. Charger On Controls an optional external battery charger on and off

Programmable Signal Inputs
The UPS incorporates four programmable signal inputs: one RS 232 input, two connectivity card inputs,
and one RPO terminal input. See figure 21 on page 21 for the locations of the ports. Configure the
inputs with the "Signal Inputs" setting in "User Settings" on page 15.
The table 11 shows the programmable settings for the signal inputs. Table 12 shows the operation logic
for the signal inputs.
Table 11. 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
Shutdown
(and restart) If active, the UPS output turns off after a user-defined delayed shutdown delay.
The batteries continue charging. Inactive input 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.
