■

light off: load not supplied;

■

light shines green: load supplied via the

inverter or the bypass AC source (via the
static bypass).

The buzzer sounds in the following situa-
tions:

■

load supplied by the bypass AC source;

■

load on battery;

■

operating problems.

It sounds slowly and discontinuously for a
minor problem or when the inverter is on
battery power. 
When the alarm "LOW BATTERY SHUT-
DOWN" is activated, the buzzer sounds
more rapidly. Finally, if the inverter shuts
down, the beep is loud and continuous.
The buzzer may be reset by pressing a
button. If the buzzer is reset, a higher
level alarm will set it off again.

This button is used to start the inverter
locally.

This button turns the inverter off locally.

These keys are used to select commands
in the main menu and access the sec-
ondary messages.

This key is used to validate the user’s
choice.

This key is used to access the main
menu: display language, display-contrast
setting, sound level of the buzzer, lamp
test, date and time settings, inverse-video
and event log.

This key is used to access voltage mea-
surements:

■

normal AC source phase-to-phase volt-

ages;

■

bypass AC source phase-to-phase and

phase-to-neutral voltages;

■

load phase-to-phase and phase-to-neu-

tral voltages.

This key is used to access current mea-
surements:

■

normal AC source, bypass AC source

and load currents;

■

percent load;

■

load  crest factor.

This key is used to access other measure-
ments:

■

normal AC source, bypass AC source

and inverter frequencies;

■

level of active and apparent power

drawn by the load;

■

load power factor;

■

inverter load level (percent).

This indicator light indicates the presence
of anomalies.

This key is used to access the primary
messages.

This key is used to access battery mea-
surements:

■

battery voltage (or the DC voltage on

frequency converters without a battery);

■

battery current (charge or discharge);

■

battery temperature;

■

available battery backup time;

■

inverter load level (percent).

This key is used to voluntarily transfer the
load to the inverter or from the inverter to
the static bypass (return transfer). Transfer
and return transfer are carried out only fol-
lowing confirmation requested by the sys-
tem display and a warning as to the risk of
an interruption in the supply of power to
the load.

This key is used to reset stored alarms.
The system accepts resetting only when
alarms have been cleared.

This key is used to stop the buzzer.
However, new alarms set the buzzer off
again.

The display continuously indicates the
system operating status.
