4.1.6 Input Dry Contacts
There are four sets of programmable input dry contacts. The input dry contacts allow the
UPS to receive external signals from peripheral devices and let the UPS response
accordingly. Please use the touch panel to set each dry contact as normally open (NO) or
normally closed (NC). Each input dry contact can be assigned a specific event. Four out of
ten events can be assigned according to your applications. Please refer to the table below

For connection to the input dry contacts, the signal cable routing is the same as the REPO
dry contacts’ signal cable routing.
