● 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

FE port is mistaken for the RS485 port during cable connection, RS485
communication fails.
● Dry contact signals take

signals on the monitoring system.
● In a parallel system, ensure that used dry contacts properly connect to each

The monitoring interface card provides external ports as well as monitoring and
control functions for the 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 information, and
displays the UPS key information and parameters on the LCD.
