● A dry contact card port takes eect only after you set it in the software. You
need to disable unused dry contact signals.
● Set the EPO port to normally open (NO) or normally closed (NC) as required.
● If multiple UPSs are connected in parallel, connect all used dry contact signals
to each UPS.
● Signal cables must be double-insulated twisted cables. If the cable length is
within 25–50 m, the cross-sectional area must be 0.5–1.5 mm

.
● For dry contact outputs, the rated DC voltage and current are 24 V DC and 0.6
A and the maximum values are 30 V DC and 1.0 A. The rated AC voltage and
current are 24 V AC and 0.6 A and the maximum values are 30 V AC and 1.0 A.
During cable connection, ensure that the voltage and current do not exceed
these maximum values.
