Information
A separate fault and performance monitoring-system with an alarm signal function is necessary in
order to prevent personal injuries and material damages during malfunctions and in case the device
fails. Substitute operation must be taken into consideration! The design and installation of the system
must comply with local regulations and directives.
2.5
Requirements placed on the personnel / due diligence
Persons entrusted with the planning, installation, commissioning and maintenance and servicing in
connection with the frequency inverter must have the corresponding quali
fi
cations and skills for these
jobs.
In addition, they must be knowledgeable about the safety regulations, EU/EC directives, rules for the
prevention of accidents and the corresponding national as well as regional and in-house regulations.
Personnel to be trained or instructed and apprentices are only permitted to work on the device under
the supervision of an experienced person. This also applies to personnel undergoing general training.
Comply with the legal minimum age.
2.6
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!
•
The 5 electrical safety rules must be observed!
•
Only remove the lid from the terminal compartment (available depending on the model) with the line
voltage switched off!
•
Opening of the base lid is prohibited. Loosening the safety screws will void the guarantee!
–
Protection class of the device when complete open is IP00! It is possible to touch hazardous
voltages directly.
–
Through use of capacitors, danger of death exists even after switching off the device!
•
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 system constructor
must provide protection by enclosure in accordance with EN 61140 before the motor is connected to
a power source. This protection can be achieved for example by a guard grille (
Product
overview: Application operational area and Mounting: General notes).
•
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 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!
Danger of being sucked in!
Do not wear loose or hanging clothing, jewellery, etc., tie together long hair and cover it.
