POWER
Ground to which the isolated auxiliary power supply (15V)
and the remote commands (Remote ON, Remote BYPASS,
Remote OFF) refer
2
REMOTE ON
INPUT #1
When pin 2 is connected to pin 15 for at least 3 seconds, the
UPS is turned on
8
REMOTE OFF
INPUT #2
When pin 8 is connected to pin 15, the UPS is powered off
instantly
7
REMOTE
BYPASS
INPUT #3
When pin 7 is connected to pin 15, the power supply of the
load switches from inverter to bypass. For as long as the
connection remains, the UPS continues to operate from the
bypass even if the input mains voltage is shut off. If the
jumper is removed when the mains voltage is present, the
UPS resumes operation from the inverter. If the jumper is
removed when there is no mains voltage present, the UPS
resumes operation from the battery

N.B.:
The figure shows the contacts present inside the UPS, capable of carrying a max. current of 0.5A to 42Vdc.
The position of the contacts shown in the figure is with no alarm or signal present.

B
UZZER
The status and faults of the UPS are signalled by the buzzer, which will emit a sound modulated according to the operating
conditions of the UPS.
The various kinds of sound are described here below:
Sound A:
The signal is emitted when the UPS is turned on or off using the relevant buttons. A single beep confirms power-on,
activation of the battery test, cancellation of the programmed power-off. When the power-off button is kept pressed,
the buzzer emits the sound A quickly four times, before confirming power-off by emitting a fifth beep.
Sound B:
The signal is emitted when the UPS switches to bypass to compensate for the surge current due to the activation of
a distorting load.
Sound C:
The signal is emitted when the UPS switches to battery operation before the battery low signal (sound D).
Possibility of silencing the report (see paragraph “Graphic Display”)
Sound D:
The signal is emitted during battery operation when the battery low alarm threshold is reached.
Possibility of silencing the report (see paragraph “Graphic Display”)
Sound E:
This signal is emitted in the presence of an alarm or lock.
Sound F:
This signal is emitted if the battery overvoltage fault occurs
Sound G:
This type of signal is emitted when the battery test fails. The buzzer emits ten beeps. The alarm signal is
maintained by the “batteries to be replaced” LED lights up.
