RPO port

RPO is used to shut down the UPS remotely. This feature is primarily used for remotely powering down the
UPS if there is an emergency. 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 also meet the following requirements:
• The RPO cannot be connected to any utility connected circuits. Reinforced insulation to the utility is
required. The RPO switch must have a minimum rating of 27 Vdc and 20 mA and 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 that the UPS stops supplying power to the load during any mode of operation, the input power
must be disconnected from the UPS when the RPO function is activated.
NOTE: Leave the RPO connector installed in the RPO port on the UPS even if the RPO function is not
needed.
The following images illustrate the RPO connections.
