•
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 off automatically for functional reasons.
•
Automatically restart after a power failure or mains disconnection!
•
Wait for the motor to come to a complete standstill before approaching it!
•
The exterior rotor turns during operation of the external rotor motor!
Risk of entanglement!
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!
