Signal inputs can be configured see Settings > Comsettings > Signal Input in Table 6 to have one of the following functions:Function DescriptionNo No function, please choose a function if you want to use inputsignalRPO Remote Power Off (RPO) is used to shutdown the UPS remotelyROO Remote On/Off allows remote action of button to switch On/Offthe UPS.(Cold start is prohibited while using the ROO function)Forced bypass If feeding the load the unit goes to bypass operation and staysthere regardless of the bypass state until the input isinactivatedBuilding alarm Active input generates an alarm “building alarm”On generator Active input disables synchronization and transfers to bypassRemote shutdown Active input turns UPS output (or outlet groups) off after a userdefined shutdown delay but keeps on charging batteriesaccording to a selected charging scheme, inactive input doesnot abort shutdown countdown. Depending on the “Restart”parameter (see Settings > Com Settings > Shutdown commandson page 16) the unit may startup automatically.! IMPORTANTWarning Signal inputs have no function by default please choose a function through the LCD (Settings > Comsettings > Input signals).See below 2 examples of configuration with RPO terminal used as RPO function and ROO terminal use asROO function:Remote Power Off (RPO)RPO is used to shutdown the UPS remotely when the contact is open. This feature can be used for shuttingdown the load and the UPS by thermal relay, for instance in the event of room over temperature. When RPO isactivated, the UPS shuts down the output and all its power converters immediately. The UPS remains on toalarm the fault. The RPO circuit is an IEC 60950 safety extra low voltage (SELV) circuit. This circuit must beseparated from any hazardous voltage circuits by reinforced insulation.• The RPO must not be connected to any utility connected circuits. Reinforced insulation to the utility isrequired. The RPO switch must be a dedicated latching-type switch not tied into any other circuit. The RPOsignal must remain active for at least 250 ms for proper operation.• To ensure the UPS stops supplying power to the load during any mode of operation, the input power mustbe disconnected from the UPS when the Remote Power Off function is activated.Leave the RPO connector installed in the RPO port on the UPS even if the RPO function is not needed.UPS Remote Control Functions
