1.2. Safety
1.2.1. Principle
To operate safely, this equipment must be transported, stored, handled, installed and
serviced correctly. Following the safety instructions described in each section of this
document is mandatory. Servomotors usage must also comply with all applicable standards,
national directives and factory instructions in force.
DANGER: Non-compliance with safety instructions, legal and technical
regulations in force may lead to physical injuries or death, as well as
damages to the property and the environment.
1.2.2. General Safety Rules
Generality
DANGER: The installation, commission 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) and local regulations.
They must be authorized to install, commission and operate in accordance
with established practices and standards.
Electrical hazard
Servo drives may contain non-insulated live AC or DC components.
Respect the drives 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 subjected to
dangerous voltages, when the motor is driven by the inverter , when the
motor rotor is manually rotated, when the motor is driven by its load, when
the motor is at standstill or stopped.
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.
Allow at least 5 minutes for the drive's capacitors to discharge to safe
voltage levels (<50V). Use the specified meter capable of measuring up to
1000V dc & ac rms to confirm that less than 50V is present between all
power terminals and between power terminals and earth.
The motor must be permanently connected to an appropriate safety
earth.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
rotating part of the machine. The work place must be clean, dry.
General recommendations :
- Check the wiring circuit
- Lock the electrical cabinets
- Use standardized equipment.
