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 speci
fi
cations 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 quali
fi
ed personnel acquainted with the
thereby associated hazards.
Attention!
Automatically restart after a power failure or mains disconnection!
2.7
Modi
fi
cations / interventions in the device
Attention!
For reasons of safety, no unauthorized interventions or modi
fi
cations may be made on the device. All
planned modi
fi
cations 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 (
“
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.
2.9
Employment of external personnel
Maintenance and service work are frequently carried out by external employees who often do not
recognize the speci
fi
c situations and the thus resulting dangers.These persons must be comprehen-
sively informed about the hazards in their area of activity.
You must monitor their working methods in order to intervene in good time if necessary.
