In a parallel system, ensure that used dry contacts properly connect to each UPS.
The monitoring interface card provides external ports as well as monitoring and control
functions for the MDU. The ports include the ambient temperature and humidity sensor port,
FE port, battery temperature monitoring port, and network management port. MDU functions
include monitoring of the UPS, allowing users to set parameters, command delivery,
information reports, and UPS key information and parameters displayed on the LCD.
