Installation
E451 is supplied with the box closed. Therefore, when installing it first of all we have to remove the 4 anti-
vandal screws having a point for a special screw-driver (
in Figure 9). This way, the equipment is separated
in two pieces (see Figure 9):
PIECE 1:
Electronic board and loudspeaker attached to the aluminum middle plate. The latter is fastened to the
stainless steel front and is locked with the anti-vandal button crossing both of them. Furthermore, it is
included the microphone with a wrapping that avoids harmful vibrations for the audio quality.
PIECE 2:
Flush-mount sheet box. It has to be fixed by 4 wall bolts, two at each side. It has 5 further holes for an easy
and safe cabling.
