Output Dry Contacts

There are six sets of programmable output dry contacts. Please use the touch panel to set
each dry contact as normally open (NO) or normally closed (NC). Each dry contact can be
assigned a specific event. Six out of twenty-one events can be assigned according to your
applications. Please refer to the table below and 7.6.6 Dry Contact Setting.
NOTE:
Since the output dry contacts belong to the secondary circuit, the voltage of each
dry contact's connected device should not exceed 60Vdc/ 42Vac to avoid electric
shock or insufficient insulation.
