Signal inputs can be configured (see Settings > Comm settings > Signal Input) to have one of the following
functions:
Table 20. Programmable Signal Input Details
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 a button or other
interface to switch On/ Off the UPS. (Cold start is prohibited
while using the ROO function.)
Building alarm Active input generates an alarm "building alarm".
Shutdown commands 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.
Signal inputs have no function by default; please choose a function through the LCD (Settings > Com settings
> Input signals).
See the following two examples of system configuration with the RPO terminal used as RPO function and the
ROO terminal use as ROO function:

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 25 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 a 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.
