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 forbidden to carry out work on live device parts. The degree of protection for the open device is
IP00! Potentially fatal voltages can be touched 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 5 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 5 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!
Even after switching off, dangerous temperatures can still occur in and on the device.
Attention!
Automatically restart after a power failure or mains disconnection!

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.
Use only genuine spare parts / genuine wearing parts / genuine accessories from ZIEHL-ABEGG.Th-
ese parts were speci
fi
cally designed for the device. There is no guarantee that parts from non-original
sources are designed and manufactured in correspondence with load and safety requirements.
Parts and optional equipment not supplied by ZIEHL-ABEGG are not approved by ZIEHL-ABEGG for
use.
2.8
