Programmable signal inputs The 5PX incorporates several 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 > Comm settings > Signal Input) to have one of the following functions: Function Description No No function. (Please choose a function if you want to use input signal.) RPO Remote Power off (RPO) is used to shutdown the UPS remotely. Remote On/Off allows remote action of a button or other interface to switch On/ ROO Off the UPS. (Cold start is prohibited while using the ROO function.) Building alarm Shutdown commands Active input generates an alarm "building alarm". 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 (see Settings > Comm Settings > Shutdown commands) the unit may startup automatically. Warning: signal inputs have no function by default; please choose a function through the LCD (Settings > Com settings > Input signals). 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 example, in the event of room over temperature. When RPO is activated, the UPS turns off the output and shuts down all power converters immediately (except for logic power). 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. RPO connections: RPO Connector type Terminal rating Comments Terminal, 14 AWG Maximum wires 60 V DC/30 V AC 20 mA max Remote On/Off (ROO) • Remote On/Off allows remote action of button to switch On/Off the UPS. • When contact changes from open to closed, the UPS is switched-on (or stays On). • When contact changes from closed to open, the UPS is switched-off (or stays Off). 614-40095-00 27
