2.2.3 Operator release
ATTENTION:
• The fitter must permanently fix the label describing the manual release operation close to the manual release lever.
• The activation of the manual release could cause an uncontrolled movement of the door in the event of mechanical damage or unbalanced conditions.
• Before performing the manoeuvre switch off the electricity supply to the automation.
This command is used in the event of a blackout or system faults, to release the operator transmission and allow manual moving of the sectional/up-
and-over door.
a) Pull the cord connected to the mobile trolley
(1)
and move the door manually.
b) The door is now free and can be moved by hand.
c) To reconnect the transmission take the door to the initial position until it hooks back up.
ATTENTION: for garages that do not have a second access, the ASEC PR device for manual release from outside must be installed

WIRING AND CONNECTIONS
• The operator may only be connected to a suitable control unit manufactured by Life.
• A
ll wiring and connection operations must be carried out with the operator disconnected from the electricity supply; if the disconnection device is not
n view, display a sign reading “ATTENTION: MAINTENANCE WORK IN PROGRESS”.
The internal operator wiring performed by the Manufacturer, may not be modified under any circumstances.
This manual does not describe how the electrics system should be prepared for connection to the mains however it gives the following warnings:
•
The electricity power line must be installed and connected by a qualified technician or professional fitter.
• The electricity supply line must have adequate protection against short circuits and must be earthed.
• The power supply network must contain a unipolar disconnection device with an opening distance of the contacts equal or greater than
3.5 mm that assures the complete disconnection of the power supply.
