The following safety instructions and warnings are intended to avert hazards and to prevent property damage and personal injury.
Please keep these instructions in a safe place.
Caution
Important safety instructions.
Caution! Failure to observe these instructions can lead to serious injuries.
Follow the safety instructions contained in EN 12453, EN 12445 and BGR 232.
▪Work on the electrical installation, the electrical or electronic systems and units may only be carried out by
a qualified electrician.
▪Assembly may only be carried out by a trained and authorised specialist.
▪Before using it for the first time, the door system must be inspected by an expert to ensure that it is in a
safe condition.
▪Stop the door system and disconnect it from the mains power supply when maintenance and cleaning is be‐
ing performed either on the system itself or in the immediate vicinity.
▪Always ensure adherence to the pertinent national accident prevention regulations. Suitable protective
clothing must be worn when installing the drive.
▪When electrical or electronic equipment and units are operated, certain components are live. Physical inju‐
ries or damage to property can result in the event of unauthorised interventions or failure to heed warnings.
▪All applicable standards and regulations for electrical installation must be complied with.
▪Only use spare parts, tools and accessory devices which have been approved by the drive manufacturer.
▪Unapproved third-party products or modifications to the system and its accessories represent a risk to your
safety and the safety of others. This means that the use of unapproved third-party products, or modifica‐
tions which have not been agreed with or approved by us, are prohibited. We do not accept liability for dam‐
age or injury arising from such actions.
▪The limits given in the technical data must not be exceeded.
▪When installing the drive at a height of less than 2.50 m, the drive must be covered as contact with the mo‐
tor could result in burns.
▪An adequate clearance distance must be maintained between the drive and combustible materials.
▪When the safety limit switches are open, the control unit used must switch the drive off:
- In the case of drives with cam-operated limit switching: Safety limit switches S1F, S2F, S3F, S4F
- In the case of drives with absolute value encoders: Safety limit switches S3F, S4F
▪The door system must be protected against falling.
- In the case of drives for use on a sectional door or an indirectly operated door system, a suitable mecha‐
nism must be provided by the customer (external mechanism to catch the door or prevent it from rolling
down) in order to reliably prevent the leaves/door from falling down in the event of failure of the load-bear‐
ing medium (e.g., cables or chains).
- In the case of drives with a light chain (LK) or crank handle (HK) it must be ensured that the torque acting
on the drive is less than the static holding torque stated in the technical data should the spring break or
counterweight fail. If this is not the case, when using these drives the door must be prevented from falling
down through the installation of an anti-drop or spring break safety device.
