MECHANICAL ASSEMBLY
a) Remove the coverplate on the right side of the door, pressing lightly on
the points indicated by the arrows in Figure 1 and open the door.
b) Drill holes in the backplate at the top or bottom to pass the wires through.
See the example in figure 2.
c) Screw the backplate to the wall using 4 screws (not supplied) to match the
holes illustrated in Figure 3.
d) Shut the door by securing it with the 2 screws provided.
Replace the screw caps removed earlier from the door (see point a).
e) The door lock (an optional accessory) can be installed in 3 different
positions on the door, the holes to be drilled are indicated on the back.
Each position on the door represents a different position where the
disconnector can be mounted.
N.B.: to make it easier to wall mount the backplate, remove the door by pressing lightly on the left side (the side that the door is attached by). You will
also have to separate the base from the keypad by disconnecting the keypad
cable.
