Installing the MX-DoorMaster
Preparing the In-Wall Socket (Solid Wall)
An in-wall socket must usually be tted rst. Make sure that the socket you use is as ush
with the wall as possible to ensure proper installation. Also make sure that the socket and
MX-DoorMaster are aligned correctly.
Aer connecting the cables, there are two ways to attach the door opener board to the
in-wall socket:
1. Secure the housing and board directly to the socket by fastening two small screws in the
a and b positions (see g.) However, this requires that the socket is properly aligned in
the wall. Thanks to the elongated shape of the screw holes, it is possible to make small
adjustments to the le and to the right when tightening the screws.
2. Use four or two Torx screws/screw anchors (diagonally opposite one another) to
tightly screw the housing and board to the wall. We recommend using this procedure
if the installed in-wall socket is not properly aligned or is not ush with the wall, or
if the MX-DoorMaster could easily be pulled out together with the in-wall socket.
The in-wall socket used must be ush with the wall.
