Work on the device

Information
Mounting, electrical connection, and start-up operation may only be carried out by an electrical
specialist in accordance with electrotechnical regulations (e.g. EN 50110 or EN 60204)!
Danger due to electric current
It is generally forbidden to carry out work on electrical live parts. Protection class of the device when
•
open is IP00! It is possible to touch hazardous voltages directly.
The safe isolation from the supply must be checked using a two-pole voltage detector.
•
Even after disconnecting the mains voltage, life-threatening charges can appear between the
•
protective ground "PE" and the mains connection.
• The protective earth is conducting high discharge currents (dependent on the switching frequency,
current-source voltage and motor capacity). Earthing in compliance with EN specifications shall
therefore be observed even for testing and trial conditions (EN 50 178, Art. 5.2.11). Without
earthing, dangerous voltages can be present on the motor housing.
Waiting period at least 3 minutes!
Through use of capacitors, danger of death exists even after switching off the device through
•
directly touching the energized parts or due to parts that have become energized due to faults.
It is only permitted to remove the housing cover after waiting for 3 minutes once the line supply
•
cable has been shut down. Should measurement or adjustment work be unavoidable on the opened
unit while still powered, then this may only be performed by qualified personnel acquainted with the
thereby associated hazards.
Attention!
Even after switching off, dangerous temperatures can still occur in and on the device.
Attention!
Automatically restart after a power failure or mains disconnection!
2.7 Modifications / interventions in the device
Attention!
For reasons of safety, no unauthorized interventions or modifications may be made on the device. All
planned modifications must be authorized by the manufacturer in writing.
Only use the manufacturer's original spare parts / wearing parts / accessories. These parts are
specially designed for this device. If parts from other sources are used, there is no guarantee that they
are designed and produced for the proper loads and with the required level of safety.
Parts and special equipment not supplied by the manufacturer are not approved for use.
2.8

Operator's obligation of diligence

• The contractor or owner must also ensure that the electric systems and equipment are operated
and maintained in accordance with electro-technical regulations.
The owner is obliged to ensure that the device is operated in perfect working order only.
•
• The device may only be used as intended (see "Application").
You must periodically examine the safety equipment for their properly functioning condition.
•
The assembly instructions and/or operating instructions are always readily available at the location
•
where the device is being used, are complete and are in legible condition.
• These persons are regularly instructed in all applicable questions regarding occupational safety
and environmental protection and are knowledgeable regarding the assembly instructions and/or
operating instructions and, especially, are familiar with the safety instructions contained therein.
• All safety and warning notices attached to the device are never removed and remain legible.
