4.3.4 Monitoring Interface Card
The monitoring interface card provides external ports as well as monitoring and
control functions for the monitoring display unit (MDU). The monitoring interface
card provides the ambient temperature and humidity sensor port, FE port, battery
temperature monitoring port, and network management port. The MDU monitors
the UPS, allows users to set parameters, delivers commands, reports system
information, and displays key UPS information and parameters on the LCD.
NO TICE
● The FE port resembles the RS485 port. Therefore, follow the silk screens when
you connect communications cables. If you mistake the RS485 port as the FE
port during cable connection, the WebUI communication fails. If you mistake
the FE port as the RS485 port during cable connection, RS485 communication
fails.
● Dry contact signals take effect after you set them. Disable unused dry contact
signals on the monitoring system.
● When multiple UPSs are connected in parallel, all dry contact signals to be used
need to connect to each UPS.
