installation, use and maintenance.
1 GENERAL REMARKS
These instructions apply to the following models:
C720 - C721 / E-SL 1800
The above-mentioned models are electromechanical operators designed for sliding gates with different features and technical
specifications.
A practical and functional mechanical lock that acts directly on the motor ensures the gate is locked when the operator is not
working and, therefore, no electric lock needs to be installed.
A convenient manual release device allows the gate to be maneuvered in the event of a power cut, if emergency batteries are
not installed or if the operator is not in service.
These operators, in addition to having different features and technical specifications, also differ as to the following compo-
nents: motor (larger in the C721), transformer (larger in the C721), pinion (different materials), release lever (different colors).
These assembly instructions apply to both models, unless otherwise specified.
