QC-PDS
HARDWARE
See chapter 8. INSTALLATION in this manual. It is up to the installer to comply with current
regulations and standards regarding the ground connection of the QC-PDS system. Do not use the
conduit as ground protection, use the protection ground wire inside the conduit.
Only use tools with electrical insulation.
Many components of the product, including the pc board, work with mains voltage. Do not touch.
Do not touch unshielded components or pins when under voltage.
Take proper precautions in humid environments.
To avoid electric shocks, always work in environments where the relative humidity is lower than 90%
and with no condensation at 45°C/113°F. See chapter 1. DESCRIPTION, section 1.6. AMBIENT AND
OPERATING CONDITIONS.
Do not work in explosive environments.
In order to avoid risks, harm or damages, do not work in explosive environments.
Lock the motor shaft to prevent it from turning.
The motor generates voltage when the shaft is turned. Lock the motor shaft before performing any
work on the QC-PDS system.
Do not short-circuit the DC BUS bolts or the capacitor pins.
Avoid touching the hot braking resistor (BALLAST).
Don’t allow flammable or heat sensitive substances near the braking resistor.
Make sure that any conducting element, no matter how small, cannot get inside the unit -
pollution degree 2 - because it could render the safety function (STO) inoperative.
Foreign conducting elements, dust or liquids can cause the STO safety function to stop working.
Therefore, do not use the STO safety function unless the system has been protected against
pollution by conducting substances.
Follow thoroughly the measures given by EMC.
Malfunctions (due to ignoring Electromagnetic Compatibility) can cause unexpected system
behavior. Carefully install the cables in accordance with the EMC standards. Do not adjust the unit
with unknown data. Start the system up carefully. Ignoring these warning can cause serious injury
and even death. Follow thoroughly the measures given by EMC to avoid risks and personal injury.
See chapter 8. INSTALLATION, · ELECTRICAL CONSIDERATIONS · and · EMC INSTRUCTIONS FOR
EQUIPMENT INSTALLATION · of section · ELECTRICAL CONSIDERATIONS ·.
Precautions against damage to the product
Working environment conditions.
This unit is ready to be used in industrial environments and comply with the current directives and
regulations of the European Community.
FAGOR AUTOMATION is not responsible for any damages incurred or damages to any installations
carried out under other conditions (residential or domestic environments).
Appropriate installation site.
Whenever possible, we recommend that the QC-PDS system is installed away from coolants,
chemicals, blows, etc. that could damage it. Keep foreign elements such as chips, screws or wire
pieces away from the units. Foreign conducting elements may damage the product or generate
parasite voltages. Ensure there is a sufficient heat dissipation system.
This unit meets the European Directives on Electromagnetic Compatibility. Nevertheless, it is
recommended to keep it away from sources of electromagnetic disturbance, such as:
Powerful loads connected to the same mains as the unit.
Nearby portable transmitters (radio-telephones, ham radio transmitters).
Nearby radio / TC transmitters.
Nearby arc welding machines.
Nearby high voltage lines....
Enclosures.
It is up to the machine manufacturer to guarantee that the enclosure of the unit meets all the relevant
directives of the European Union.
Ground connection of the power supply
The ground (or zero volt) point of the auxiliary power supply must be connected to the main ground
point of the machine. Poor grounding increases the risk of electric shock.
