2.7 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. DIN EN 50110
or DIN 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.
•
When operation with a frequency inverter the protective conductor is carrying high
discharge currents (irrespective of the clock frequency, current-source voltage and
motor capacity). Earthing in compliance with VDE 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.
•
Maintenance work may only be carried out by suitably quali
fi
ed personnel.
Attention, automatic restart!
•
The fan / motor may switch on and off automatically for functional reasons.
•
After power failure or mains disconnection an automatic restart of the fan takes place
after voltage return! Therefore the fan must be disconnected from voltage before
doing any work (see service work).
•
Wait for the fan to come to a complete standstill before approaching it!
Danger of being sucked in!
Do not wear loose or hanging clothing, jewellery, etc., tie together long hair and cover it.
2.8 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.These 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.
