Configure the Output Relays

  1. From the main menu, tap Configuration > Contacts and relays and select the output relay that you want to configure.
  2. Select the function(s) you want to assign to the output relay. On each page, tap OK to save your settings and tap the arrow symbol to go to the next page.
    NOTE: It is possible to assign several functions to the same output relay.
    Battery charge: When the battery enters the equalization or float charge, the dry contact signal is activated via a relay. Battery discharge: When the battery starts discharging, the dry contact signal is activated via a relay.
    Battery voltage low: When the battery is in low voltage, the dry contact signal is activated via a relay. Battery mode: When the UPS is in battery discharge mode, the dry contact signal is activated via a relay.
    BB shunt trip: When a battery-related alarm occurs, the UPS will send a signal to disconnect the battery, and simultaneously, an auxiliary dry contact signal will be activated via a relay. Not configurable for output relay 4. BB under voltage trip: When a battery-related alarm occurs, the dry contact signal (24 V) is activated via a relay to disconnect the external battery disconnect device.
    Bypass backfeed trip: When the bypass backfeed occurs, the UPS will trigger an alarm to indicate the bypass fault, and simultaneously, an auxiliary dry contact signal will be activated via the isolation of a relay. EPO active: When the EPO is activated, a dry contact signal is activated via a relay.
    General alarm: When one or more warnings are triggered, an auxiliary dry contact signal is activated via the isolation of a relay. Main power supply not available: In an event of mains abnormality, a dry contact signal is activated via a relay.
    Main backfeed trip: When the mains backfeed occurs, the UPS will trigger an alarm to indicate the mains fault, and simultaneously, an auxiliary dry contact signal will be activated via the isolation of a relay. Normal mode: When the UPS is in normal operation mode, the dry contact signal is activated via a relay.
    On bypass: When the UPS is in bypass operation mode, the dry contact signal is activated via a relay. On Inverter: When the UPS is in inverter mode, the dry contact signal is activated via a relay.
    Overload: When the UPS is overloaded, a dry contact signal will be activated via a relay. It is mandatory to set this function when the UPS is powered on for the first time. Output lost: When the load is disconnected, a dry contact signal is activated via a relay.
    Rectifier ready: When the rectifier is ready, the dry contact signal is activated via a relay.
