Programmable Signal Inputs
The 9PX 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
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
ROO
Remote On/Off allows remote action of button to switch On/Off
the UPS.
(Cold start is prohibited while using the ROO function)
Forced bypass
If feeding the load the unit goes to bypass operation and stays
there regardless of the bypass state until the input is
inactivated
Building alarm
Active input generates an alarm “building alarm”
On generator
Active input disables synchronization and transfers to bypass
Remote shutdown
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 > Com Settings > Shutdown commands
on page 16) the unit may startup automatically.
!
IMPORTANT
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 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.
Leave the RPO connector installed in the RPO port on the UPS even if the RPO function is not needed.
