REMOTE ON
INPUT #1
By connecting pin 2 with pin 15 for at least 3 seconds the
UPS switches on

BYPASS
INPUT #3
By connecting pin 7 to pin 15 the load power supply switches
from inverter to bypass. For as long as the connection is
made, the UPS continues to operate on bypass even if the
input mains supply fails. If the jumper is removed with the
mains power supply present, the UPS will resume operation
and the load will be powered by the inverter. If the jumper is
removed with the mains power supply fails, the UPS will
resume operation on battery power.

>9.1 EMERGENCY SHUTDOWN (R.E.P.O.)
This insulated input is used to switch off the UPS in an emergency. The UPS is supplied with the "Remote
Emergency Power Off" (R.E.P.O.) terminals short circuited. At installation, remove the short-circuit and connect to
the normally closed contact of the shutdown device, using a double-insulating cable.
When activated from a remote push-button or other device in an emergency, the R.E.P.O connection opens
and the UPS switches to stand-by mode. The UPS no longer powers the load.
The R.E.P.O circuit is supplied with SELV type circuits. No external supply voltage is required. When it is closed
(normal condition), a maximum current of 15 mA flows.
After an emergency shutdown, the UPS will return to on-line operating mode only when it receives a startup
command from the mimic panel (provided that the Remote Emergency Power Off device is not still active).
