6.2 Checking the circuit breaker
1. To open the door of the Sunny Central when the cabinet is switched on, remove the handle from
the extension spindle that connects the switch to the handle. The door can then be opened.
2. Switch the Sunny Central to "Stop" and open the
doors.
3. Ensure that the Sunny Central is connected to a
control voltage (supply voltage) and is supplied
with power.
4. Tape door contact switch to the "On" position.
5. Switch the Sunny Central to "Start".
6. Check the residual current breaker by pressing
the function test button (A).

7. Switch the Sunny Central to "Stop".
8. Release door contact switches (remove the
adhesive tape).

The circuit breaker is connected with the door via an
extension spindle. The door itself has no contacts
since it cannot be opened when the switch is
activated.
