Attention!
To install the motor unit correctly, the
following points must be assured:
- The motor unit console must be
aligned to face the gate, so that the
spur gear can mesh with the toothed
rack whatever the position of the gate.
- The wall plugs for the floor console
must be at least 80 mm from the
edge of the foundations.
- After installation and commissioning,
all the covers must be reattached to
the motor unit.
