5. MECHANICAL INSTALLATION
5.2 Post Bracket Position and A&B Dimensions
Determine the A and B dimension based on the opening angle provided in Table 1 to confirm the position where the post bracket will be mounted.
1. To ensure that the motor does not touch the pillar, please define your C dimension using B-60 mm formula.
2. For optimal mechanical advantage A and B dimension shall be equal or not differ by more than 40 mm.
NOTE: Smaller A and B dimensions determine higher peripheral speed of the leaf. Higher differences between A and B dimensions cause greater speed and force variati-
ons during the gate opening and closing movement. It is always good practice to use all available travel of the operator.
All crushing points must be secured by an entrapment protection according to EU: EN 12453, EN 60335-2-103; GB (UK, NI): BS EN 12453, BS EN 60335-2-103.
