Page 5: General
General General Information relating to the installation instructions The classification of the contents is based on the life stages of the linear drive (here- inafter referred to as the “device”). The manufacturer reserves the right to make changes to the technical specifications stated in these installation instructions. In detail these can differ from the respective version of the device without the factual information being fundamentally changed and without losing their validity. The cur- rent status of the technical specifications can be requested from the manufacturer at any time. Any claims arising from this cannot be asserted. Deviations from the text and pictorial statements are possible and are dependent on the technical develop- ment, equipment and accessories of the device. -

Page 10: Safety Principles
Safety Safety principles The device is built according to state-of-the-art technology and the generally accepted rules of safety and it is safe to operate. The basic safety and health requirements of the applicable laws, standards, directives and guidelines have been applied in the construction of the device. The safety of the device is con- firmed by the Declaration of Incorporation. All specifications pertaining to safety relate to the currently valid regulations of the European Union. In other countries it must be ensured by the plant operator that the applicable laws and national regulations are complied with. In addition to the safety notices and directions in these installation instructions, the generally applicable regulations regarding accident prevention and environ- mental protection must be observed and complied with. The device must only be used when in perfect working order, for its intended use, and in compliance with the safety notices and directions in these installa- tion instructions. -
Page 11: General Duties Of The Plant Operator
Safety General duties of the plant operator The plant operator is obligated to use the device only in perfect and opera- tionally safe condition. He must ensure that, in addition to the safety notices and directions in the installation instructions, the generally accepted safety and accident prevention regulations, the specifications of DIN VDE 0100 and the provisions relating to environmental protection of the respective country of use, are heeded and complied with. The plant operator is responsible that all work with the device is performed only by trained, safety instructed and authorized personnel. Ultimately responsible for accident-free operation is the plant operator of the device or the personnel authorized by the plant operator. The plant operator is responsible for compliance with the technical specifi- cations, in particular for compliance with the static loads. Non-compliance with the static loads may cause loss of the support or holding function. -
Page 12: Safety Notices And Directions Relating To The Technical Condition
Safety Safety notices and directions relating to the technical condi- tion The device must be checked before installation for damage and proper condition. The plant operator is obligated to operate the device only in perfect and operationally safe condition. The technical condition must comply with the legal requirements at all times. If dangers to personnel or changes in operating behaviour are recognized, the device must be shut down immediately and the incident reported to your superiors or to the plant operator. -
Page 13: Safety Instructions Relating To Operation
Safety Safety instructions relating to operation The operator of the device is obligated to ensure the safe and proper state of the device before the initial start of operation. This is also necessary during operation of the device at regular intervals to be determined by the plant operator. In the event of a fault, misuse and/or if control components are not con- nected correctly, this can cause the supporting and retaining function of the device to be impaired. -

Page 16: Information Relating To The Self-Locking Facility
Product description 3.3.2 Information relating to the self-locking facility WARNING Danger of injury through loss of the self-locking facility. Crushing and fatal injuries are possible. • Use device with a brake. CAUTION Possible damage to the device or customer’s machine through loss of the self- locking facility. • Use device with a brake. With the devices it is differentiated between dynamic and static self-locking. Dy- namic self-locking arises from movement and static self-locking when the device is at a standstill. The self locking facility on the devices is dependent on various... -
