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 rotor is not protected against indirect contact neither by supplementary or reinforced insulation
nor by connection to safety-earth in accordance with EN 60204-1, therefore the motor/fan must be
installed so that it is not touchable.
•
When the motor runs independently due to air
fl
owing through or if it continues to run down after
being turned off, dangerous voltages of over 50 V can arise on the motor internal connections
through operation of the generator.
•
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 voltage supply.
•
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.
•
Maintenance work may only be carried out by suitably quali
fi
ed personnel.
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.
•
The controller housing may only be removed or opened when the power line has been switched off
and a period of three minutes has elapsed since switching it off.
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!
•
Wait for the fan to come to a complete standstill before approaching it!
•
The exterior rotor turns during operation of the external rotor motor!
Danger of being sucked in!
Do not wear loose or hanging clothing, jewellery, etc., tie together long hair and cover it.
Attention, hot surface!
Temperatures of above 85
°
C can occur on the motor surfaces, especially on the controller housing!

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.
