4.3 Output Interface (Remote Alarms) Board (100215120007 & 100215120002)

4.3.1 Alarm Outputs

Two remote alarm boards, shown in figure 23 & 24, similar in function and differing only in their connections to the terminal blocks M1 - M3, enable the alarm signals generated within the UPS to be connected by means of volt-free changeover relay contacts to a remote monitoring device.

4.3.2Remote Control Inputs

Note: When using the above contacts for remote alarm annunciation, the power supply for the remote indicators must be provided from an external power source. Under no circumstances should the UPS internal low voltage supplies be used for this purpose.

Both board have facilities to accept two remote control inputs, as shown in figures 23 and 24. One remote input allows the inverter to be shut down (transferring the load to the bypass supply) and the other enables the inverter synchronisation feature to be inhibited. This facility is valid only for single module. The inverter synchronisation inhibit feature is most often used if the UPS is powered from a standby generator when the input mains supply fails and the generator frequency is unstable.

The external control signals (12V / 24V) should be connected to terminal block M2 as shown. Once again, the voltage applied to these terminals must be generated by an external power source and not taken from the UPS internal low voltage supplies.
