Mains failure
This signal (between Pin 2 and Pin 4 contact closed) is given if the mains input is out of the
allowed operating limits, and disappears when the mains input comes to its normal conditions.
Low battery
This signal (between Pin 5 and Pin 4 contact closed) is given if the battery capacity is less than
30%.
By-pass active
This signal (between Pin 1 and Pin 4 contact closed) is given if the load is supplied by the by-pass
input.
Summary alarm
This signal (between Pin 8 and Pin 4 contact closed) is given if battery mode, low battery, by-pass
active or “Fault” sign is blinking.
An example of free contact communication is given below. If the system in communication sends DC
signal, in order to cut the current, R resistors must be 50 k. If the current, which will be carried by the
contacts is greater than 0,1Ma, it is necessary to use the DSP UPS relay-interface board ( stock code=
105430010065) which can be purchased as an accessory.
5.1.3.5.2 Communication via serial port
RS232 serial communication port is connected to 9Pin D-SUB-male connector. Pin connections are as
follows;
GND - Pin 5 ,
TXD - Pin 3 ,
RXD - Pin 2 ,
The remaining pins do not have any connection.
