8.4 UPS Remote monitoring panel connection
Remote monitoring panel is used to monitor the UPS from 400m distance. This panel is installed to con-
trol/monitor room. If the distance is less than 25m then RS232 cable is used, and RS485 for larger distances.
Additional adaptor is required for RS485.
The remote monitoring panel transfers the data to the user from the UPS. The remote monitoring panel re-
quires 220Vac 50Hz AC voltage to operate, and it is better to use the output of the ups as a power supply.
