Description
SELECT key
UPS on bypass mode, the output voltage,
frequency and bypasss enabling/disabling can
be selected by pressing the key SELECT and
validated with ENTER.
ENTER key
OFF
UPS shutdown
Press for more than 1 sec. the key OFF.
The inverter is shutdown and the output is
transferred over the bypass. If there is power
supply and bypass is activated (code «1»), the
outputs (schuko outlets and specific terminals)
supplies voltage direct from mains through the
static bypass.
Consider by default that the bypass is
deactivated from factory (code «0»), so in this
conditions when pressing the key OFF, there
will not be voltage at the output.
With this key an alarm can also be deactivated
on bypass mode.
ON
MUTE
UPS start up
Press for more than 1 sec. the key ON. An
automatic battery test is done and then the
inverter is started up.
Each time that the inverter is started up, an
automatic battery test is done.
Acoustic alarm
silencer
With the equipment started up, the acoustic
alarm on battery mode can be silenced, by
pressing the over the key ON, of double function,
in this case as MUTE. It doesn’t disable the
alarm permanently, because when any alarm is
activated again, including the silenced on, the
acoustic alarm is activated again.
Battery test
When pressing this key, the equipment can
make the battery test, on line mode, on ECO
mode or on converter mode.

(*1) Screen that UPS, ECO or CVF can be selected as operating
modes of the equipment, where:
UPS: Setting of normal inverter (Line mode).
ECO: Setting of Economy mode (Standby mode).
CVF: Setting of the equipment as frequency converter.
The detailed illustration of the three modes and operation of the
configuration are described next.
