1.2.2. General Safety Rules
Generality
DANGER: The installation, commissioning and operation must be
performed by qualified personnel, in conjunction with this
documentation.
The qualified personnel must know the safety (C18510 authorization,
standard VDE 0105 or IEC 0364 as an example) and local regulations.
They must be authorized to install, commission and operate in
accordance with established practices and standards.
Electrical hazard
Inverters may contain non-insulated live AC or DC components. See
the inverter commissioning manual. Users are advised to guard against
access to live parts before installing the equipment.
Some parts of the motor or installation elements can be subject to
dangerous voltages, especially when the motor is driven by the
converter or when the motor rotor is manually rotated.
For measurements use only a meter to IEC 61010 (CAT III or higher).
Always begin using the highest range. CAT I and CAT II meters must
not be used on this product.
Even after the electrical system is de-energized, voltages may be
present several minutes (see inverter technical manual) until the power
capacitors have had time to discharge. Use specified meter capable of
measuring up to 1000V DC & AC RMS to confirm that less than 50V is
present between power terminals an earth. Check the inverter
recommendations.
The continuity of the grounding circuit has to be checked on the
complete circuit : the resistance between any conductive point and the
grounding conductor shall not exceed more than100mΩ.
To prevent any accidental contact with live components, it is necessary
to check that cables are not damaged, stripped or not in contact with a
rotational part of the machine and to study first of all the following points:
- Connector lug protection
- Correctly fitted protection and earthing features
- Workplace insulation (enclosure insulation humidity, etc.)
- Terminal box properly closed
General recommendations :
- Check the bonding circuit
- Lock the electrical system
- Use standardized equipment
Due to particular high current values, take care of specific hazards like
burning or UV flashes during shorts.
