Checking the internal RCCB
To ensure the continuing safe operation of the wallbox, you must test the function of the integrated RCCB (Twin wall-
boxes: both RCCBs) yourself every 6months: each RCCB has a push button with which to initiate the test function.
Proceed as follows to test the RCCB:
1 Open the housing cover of the wallbox using the
triangular key and lower it.

2 Locate the RCCB (TWIN wallboxes: both RCCBs)
and press the button engraved T or marked Test.
y The RCCB must now trip and flick its pivot lever
into the centre position (connection to the elec-
tricity grid is interrupted).
3 Now flip the RCCB first to the 0 position and then
back to the I position.

4 Flip the housing cover up so that it clicks into the
housing and lock it with the triangular key.
