CAUTION DANGER
Before installing a wall unit, make sure the wall
is made of solid brick, concrete or materials
with similar strength characteristics. The load
capacity of the wall must be sufficient to
support at least four times the weight of the
unit.
1 Mark the positions of the holes for the brackets
according to the measurements in the mounting
dimensions diagram (see "Fig. 6").
2 Drill the holes for the expansion anchors.
3 Clean the holes from dust and concrete residue.
4 Insert a washer and nut at the end of each expansion
plug.
5 Screw the expansion bolts into the holes of the
mounting brackets, place the brackets in position and
hammer the expansion bolts into the wall.
6 Check that the mounting brackets are aligned.
7 Lift the unit carefully and place the mounting feet on
the brackets.
8 Screw the unit firmly to the brackets.

ATTENTION ELECTRIC DANGER
Before making electrical connections, turn off
the main switch of the system.
1 Prepare the cable for connection:
– Using a wire stripper, strip the rubber sheath at
both ends of the cable and expose approximately
40 mm of the internal conductors.
– Strip the insulation sheath at the ends of the
conductors.
– Using a crimping tool, crimp U-type wire terminals
to the ends of the conductors.
m
CAUTION
When crimping, clearly identify live cables ("L")
and other cables.
2 Unscrew and remove the terminal block cover.
3 Unscrew the cable clamp under the terminal block
and hold it aside.
