 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
