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 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.
•
Maintenance work may only be carried out by suitably quali
fi
ed personnel.
Attention, automatic restart!
•
The motor may switch on and o
ff
automatically for functional reasons.
•
Automatically restart after a power failure or mains disconnection!
•
Wait until the motor has stopped before approaching.
•
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
electronic housing!
