Connecting DC supply back-up
When using DA430 swing door operator together with DC supply back-up, current
supply have to be limited. This is done by connecting 0,5 Ohm (2W) resistor and current
supply in series.
Resistor is protecting operator’s control unit. If resistor is not used, unlimited current of
DC supply back-up can break control unit’s motor control components.
No battery charging or maintenance is provided by DA430.
7 INTERNAL CONNECTIONS
Electrical connections should be made by a qualifi ed electrician.
- The power plug or an optional external switch must have
an easy access.
- The concealed mains installation must be equipped with an external
switch providing all pole disconnection.
- Keep the mains disconnected during installation.
