DRY CONTACT This UPS offers users the solution for UPS status monitoring via two output relays. Refer to Network Operation in this manual, verifying the UPS is connected to a computer with PowerPanel Business software installed or is equipped with RMCARD. Follow below circuit to wire your dry contact port and choose your preferred monitoring status via those interfaces. UPS status which can be monitored by dry contact is listed below: UPS Status UPS Conditions Power Failure* UPS detects utility failure. Battery Low* Battery capacity is lower than threshold. Summary Alarm UPS exits alarms due to Inverter Fault, Output Short, Over Temperature, Overload, Battery Overcharge, Low Battery, Battery Disconnected, and Battery Defect. UPS Fail UPS has malfunctioned due to Inverter Fault, DC Power Fault, and Over Temperature. *Default settings of relay contacts are Power Failure and Battery Low (Normally Open).
