Input Dry Contacts - Delta Modulon DPH series User Manual

4.1.6 Input Dry Contacts

There are four sets of programmable input dry contacts (see Figure 4-10). Please use the
touch panel to set each dry contact as normally open (NO) or normally closed (NC). The
input dry contacts allow the UPS to receive external signals from peripheral devices and let
the UPS response accordingly. Each input dry contact can be assigned with a specific event.
There are four events can be assigned according to your applications. To learn how to set
up, please contact your local dealer and refer to 7.10.6 Dry Contact Setting. For information
about the four events, please refer to the table below.
