The dry contact interface card takes effect only after it is set on the monitoring system. Set the
unused dry contact signal to the unused status.

Set the EPO port to NO or NC as required.
 When multiple UPSs are paralleled, all dry contact signals to be used need to connect to each UPS.

Single cables require dual-insulated twisted cables. If the length of a power cable is within 25–50 m,
its cross-sectional area must be 0.5 mm
Hot-swappable

The FE port resembles the RS485 port. Follow the silk screen when connecting
communications cables as, if the RS485 port is mistaken for the FE port during cable
connection, the WebUI cannot be connected. Conversely, if the FE port is mistaken for the
RS485 port during cable connection, RS485 communication fails.
If MDU communication fails, the "Comm. failure" message is displayed on the LCD,
screen switching is disabled, the buzzer buzzes, and the fault indicator is red. Once the
fault is rectified, the LCD recovers, and the alarm is cleared.
Dry contact signals take effect after you set them. Disable unused dry contact signals on
the monitoring system.
In a parallel system, ensure that used dry contacts properly connect to each UPS.
