BEFORE INSTALLING
Before proceeding with the installation of the automatism, check the following:
- the structure of the door must be sufficiently sturdy, the hinges must be efficient and there must be
no friction between fixed or mobile parts;
- the path of the electrical cables must be made according to the control and safety requirements (see
the system type);
- there must be a mechanical stop ledge for door closing (fixed firmly to the ground) to prevent the
door/ gearmotor from overextending.
