ENGLISH
IMPORTANT!
For permanently connected equipment, an easily accessible connection device must be fitted to the
cabling. Connect to Earth.
Remove the button from the base by unscrewing the two retaining screws.
Connect a 230V mains cable (electric phase, L) to the central contact of the button (1 ). (Fig. 5)
Connect cables 2 and 3 from the motor gear to the two outer contacts of the button (see electrical diagram of the
motor gear to ensure correct rotation
direction of the pulley) (Fig. 5).
Connect the cable to Earth by inserting into the housing at the rear of the switch and fix with a toothed washer and
screw. (Fig. 2)
Connect a 230 V mains cable (neutral phase, N) directly to the common cable (4) coming from the motor gear. (Fig.
5).
Replace the button in its housing.
For units with a central electrical control unit, connect the button contact to the terminals on the control unit. In this
case, no electrical power must go to the button itself. (Fig. 6)
3. ELECTRICAL CONNECTION
If the power cable is damaged, it must be replaced by the manufacturer or his technical support or a similarly qualified
person in order to avoid any risks.
Do not install the product in an explosive environment or atmosphere: the presence of flammable gas or fumes is a
serious health and safety hazard.
On the wall chosen for installation, make two holes for passing the electrical power and brake cables on the back
of the shutter locking lever (Fig. 3).
At the rear of the aluminium box, in correspondence with the brake cable hole, there is a specifically created 10
mm diameter housing that can house a protective (guide) tube of the sheath, between the outer part and where the
motor gearing is installed in order to allow for ease of fitting and removal.
Make three fixing holes to screw the box to the wall (Fig. 3).
