Only use tools with electrical insulation.
Many components of the product, including the pc board, work with mains voltage. Don’t touch them.
Do not touch unshielded components or pins when under voltage.
Make sure not to work in humid environments.
To avoid electric shocks, always work in environments where relative humidity is lower than 90% without
condensation at 45 °C (113 °F).
Make sure not to work in explosive environments.
In order to avoid risks, harm or damages, do not work in explosive environments.
The motor generates voltage when turning the shaft. Before working on the servo system, lock
the motor shaft to prevent it from turning.
Do not short-circuit the terminals of the DC bus nor those of the capacitors of the DC bus.
Avoid touching the hot braking resistor.
Don’t allow flammable or heat sensitive substances near the braking resistor.
Foreign conducting elements, dust or liquids can cause the STO safety function to stop working.
Do not use the STO safety function unless the system has been protected against pollution by
conducting substances.
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 inoperative
Follow thoroughly the measures given by EMC.
Malfunctions (due to ignoring electromagnetic compatibility) can cause unexpected system behavior.
Do the whole wiring carefully according to the measures given by EMC. Do not adjust the unit with unknown
data. Start the system up carefully. Ignoring these warning can cause serious injury or even
death. Follow thoroughy the measures given by CEM to avoid risks and personal injury.
Precautions against damage to the product
Work environment.
This unit is ready to be used in industrial environments and comply with the current directives and
regulations of the European Community.
Fagor Automation shall not be held responsible for any damage that could suffer or cause when installed
under other conditions (residential or domestic environments).
Install the unit in the right place.
We recommend that, whenever possible, the servo drive system be 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.
Provide good heat dissipation.
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.
• Portable nearby transmitters (radio-telephones, CB radio emitters).
• Nearby radio/TV transmitters.
• Nearby arc welding machines.
• Nearby high voltage lines ...
Enclosures.
It is up to the manufacturer to guarantee that the enclosure where the unit has been installed meets
all the relevant directives of the European Union.
Connecting the power supply to ground.
The zero Volt point of the external power supply must be connected to the main ground point of the
machine. Poor grounding increases the risk of electrical shock.
Precautions during repairs
Do not access the inside of this unit.
Only personnel authorized by Fagor Automation may access the interior of this unit.
