Remote Control Functions 4.7 Remote Control Functions Programmable Signal Inputs The Tripp Lite by Eaton SmartOnlineUPS incorporates 3 programmable signal inputs: one Remote Power Off (RPO) input terminal, one Remote On/Off (ROO) input terminal, one RS-232 input (pin-4). Signal inputs can be configured see Settings > Com settings > Signal Input in 4.5 User Settings to have one of the following functions: Function No RPO ROO Forced bypass Building alarm On generator Remote shutdown Description No function, please choose a function if you want to use input signal Remote Power Off (RPO) is used to shutdown the UPS remotely Remote On/Off allows remote action of button to switch On/Off the UPS. (Cold start is prohibited while using the ROO function) If feeding the load the unit goes to bypass operation and stays there regardless of the bypass state until the input is inactivated Active input generates an alarm "building alarm" Active input disables synchronization and transfers to bypass Active input turns UPS output (or outlet groups) off after a user defined shutdown delay but keeps on charging batteries according to a selected charging scheme, inactive input does not abort shutdown countdown. Depending on the "Restart" parameter the unit may startup automatically. See ON /OFF settings in 4.5 User Settings. ! IMPORTANT Warning Signal inputs have no function by default. Please choose a function through the LCD (COM SETTING>REMOTE ON/OFF, REMOTE PWR OFF, INPUT DB9-4). See below 2 examples of configuration with RPO terminal used as RPO function and ROO terminal use as ROO function: Remote Power Off (RPO) RPO is used to shutdown the UPS remotely when the contact is open. This feature can be used for shutting down the load and the UPS by thermal relay, for instance in the event of room over temperature. When RPO is activated, the UPS shuts down the output and all its power converters immediately. The UPS remains on to alarm the fault. The RPO circuit is an IEC 60950 safety extra low voltage (SELV) circuit. This circuit must be separated from any hazardous voltage circuits by reinforced insulation. • The RPO must not be connected to any utility connected circuits. Reinforced insulation to the utility is required. The RPO switch must be a dedicated latching-type switch not tied into any other circuit. The RPO signal 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 must be disconnected from the UPS when the Remote Power Off function is activated. 20 Tripp Lite by Eaton SmartOnline Series User Guide 614-21326-Rev 01
