Fixation of ACC 50
The fixing boreholes of the ACC 50 are designed so that for installation either a flush-mounted box or
cavity wall installation box (60mm) can be used. The device can also be installed directly above an
empty pipe output (see drawing next page), taking into consideration that the reserve cable is either in
the installation box or in the junction socket.
