MAINTENANCE
To be undertaken by specialized staff after disconnecting power supply.
Make certain that moving parts located inside the box are greased once a year, and
check the force transmitted through the drive to the gate.
In the event that the need for servicing or repairs should arise, the speed reducer can be
removed from the box without taking down the gate.
- Lift the cover from the box, isolate the motor from the power supply by disconnecting
the cable, then remove the curved lever: the gate can now swing freely (Fig.15-A/B).
- Thereafter, loosen the four nuts which secure the fixing plate to the box and serve to
clamp the speed reducer in position.
The motor should be overhauled every two years and the oil replaced.

EMERGENCY RELEASE
To be undertaken after disconnecting power supply.
In order to carry out the manual operation of the gate leaf the followings must be
checked:
- That the gate is endowed with appropriate handles;
- That these appropriate handles are placed so to avoid safety risks for the operator;
- That the physical effort necessary to move the gate leaf should not be higher than 225
N, for doors/gates for private dwellings, and, 390N for doors/gates for commercial and
industrial sites ( values indicated in 5.3.5 of the EN 12453 norm) .
In the case of power failure, the gate may be opened manually by releasing the electric
lock, then by pushing the gate (Fig. 14).
N.B. In the case of two-leaf gates, a mechanical bolt (code ACG5000) is recommended
to ensure that the electric lock closes the gate securely.
This accessory is usually mounted at the foot of the leaf that closes first.
In closing, the second leaf touches the bolt, thereby locking the first to the ground.
The second leaf is locked to the first thanks to the electric lock, usually mounted at mid-
height.

ELECTRICAL SAFETY DEVICES
Use the K2 and KS2 electronic control board (for one or two single-phase motors).
For connections and technical data of accessories refer to the appropriate booklets.

IMPORTANT SAFETY INSTRUCTIONS FOR THE INSTALLATION
1° - Install a thermal magnetic switch (omnipolar, with a minimum contact opening of 3
mm) before the control board, in case this is not provided with it. The switch shall be
guaranteed by a mark of compliance with international standards. Such a device
must be protected against accidental closing (e.g. Installing it inside the control panel
key locked container).
2° - As far as the cable section and the cable kind are concerned, RIB suggests to use
an NPI07VVF cable, with a minimum section of 1,5mm
2
, and to follow, In any case,
the IEC 364 standard and Installation regulations In force In your Country.
3° - Positioning of an eventual pair of photocells: The beam of the photocells must be at
an height not above the 70 cm from the ground, and, should not be more than 20 cm
away from the axis of operation of the gate (Sliding track for sliding gate or door, and
the hinges for the swing gate). In accordance with the point 7.2.1 of EN 12445 their
correct functioning must be checked once the whole installation has been
completed.
4° - In order to comply with the limits defined by the EN 12453 norm, if the peak force is
higher than the limit of 400N set by the norm, it is necessary to use an active
obstacle detection system on the whole height of the gate (up to a maximum of
2,5m) - The photocells in this case must be apply externally between the colums and
internally for all the race of the mobil part every 60÷70cm for all the height of the
column of the gate up to a maximum of 2,5m (EN 12445 point 7.3.2.1). example:
column height 2,2m => 6 copies of photocells - 3 internal and 3 external (better if
complete of syncronism feature - FIT SYNCRO with TX SYNCRO).
N.B.: THE SYSTEM MUST BE GROUNDED
Data described by this manual are only Indicative and RIB reserves to modify them at
any time. Install the system complying with current standards and regulations.
