Installation and User Manual
13 "V" Key
This key is used to access voltage measurements:
◗ normal AC source phase-to-phase voltages.
◗ bypass AC source phase-to-phase and phase-to-neutral voltages.
◗ load phase-to-phase and phase-to-neutral voltages.
14 "A" Key
This key is used to access current measurements:
◗ normal AC source, bypass AC source and load currents.
◗ percent load.
◗ load crest factor.
15 "W.Hz" Key
This key is used to access other measurements:
◗ 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).
16 "Anomaly" indicator light This indicator light indicates the presence of anomalies.
17 Key
⁄⁄
This key is used to access the primary messages.
18 "Battery" Key
ıı
This key is used to access battery measurements:
◗ 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).
19 "Forced-transfer"
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 following confirmation requested by the
display and a warning as to the risk of an interruption in the supply of power to the load.
20 "Alarm reset" This key is used to reset stored alarms. The system accepts resetting only when alarms
have been cleared.
21 "Buzzer reset" This key is used to stop the buzzer. However, new alarms set the buzzer off again.
22 Display The display continuously indicates the system operating status.
