period of time. It is necessary to have at least a 35A/H deep cycle low maintenance
battery fitted, in order to provide sufficient backup capacity during days of poor
weather. For further details contact your local CENTURION agent.
DC CONVERTER MODULE (OPTIONAL FOR A10 ONLY)
The DC converter module allows the A10 gate operator to function from a 12V battery
in the absence of AC mains. The converter module steps up the 12V battery supply to
310V DC. The inverter drive on the A10 operator then switches the high voltage DC
supply to run the three phase induction motor.
WARNING
The following features are of interest to the end-user:
The converter module includes battery protection circuitry. This circuitry prevents the
converter module from being damaged in the event of reverse polarity connection. In
addition the circuitry automatically disconnects the battery when the battery drops
into a low-voltage state. This prevents the converter module from running the battery
flat and potentially damaging the battery.
There is a push button on the converter module that manually reconnects the battery
in the event of a power failure and low-battery voltage state. Upon activation, and if
the battery voltage exceeds the low-voltage parameter, the protection circuitry will
automatically keep the battery connected to the converter. If, on the other hand, the
battery voltage is below the low-voltage parameter, the protection circuitry will not
connect the battery to the converter.

The A10 converter module should be installed and
maintained by a qualified installer.
