14 WG20 Instructions
8 Refer to figure 49 for the electrical extra low voltage connection of the
various devices to the CL20 control unit terminals.
• The terminals have the same colour coding as the corresponding
devices; for example, the grey terminal (OPEN) of the KS1 selector
switch must be connected to the grey terminal (OPEN) of the control
unit.
• For most connections you do not need to observe any polarity; only
for the shielded cable of the aerial it is necessary to connect the central
core and the shield as shown in detail [B]. The cable for the motors must
be connected as shown in detail [A].
• Keep in mind that, to prevent the jamming of the two leaves, the
control unit commands the M2 motor to open first, followed by M1 (vice-
versa for the closing manoeuvre). Therefore make sure that the motor
that drives the leaf that strikes the mechanical stop is connected to
terminal M1 (outer one), while the motor that drives the other leaf must
be connected to terminal M2.
• If only one motor is used (single-leaf gate) it must be connected to
terminal M2 while terminal M1 remains free.

To facilitate the installation operations, the terminals [B] can be removed
as shown in figure 49; make the connections and then re-insert them.
When you have completed the connections, use clamps to secure the
cables to the appropriate fasteners [C].
9 To close the control unit you need to rest the cover on the bottom
approximately 3 cm above the final position, then press it down until it
snaps into place.
