 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
Only once being set will dry contact signals take effect. Set unused dry contact signals to
the unused state on the LCD.
In a parallel system, ensure that used dry contacts properly connect to each UPS.
