SAFETY CONDITIONS
Read the following safety measures in order to prevent harming people or damage to this product and those
products connected to it.
The unit can only be repaired by personnel authorized by Fagor Automation.
Fagor Automation shall not be held responsible of any physical or material damage originated from not
complying with these basic safety rules.
PRECAUTIONS AGAINST PERSONAL HARM
• Interconnection of modules.
Use the connection cables provided with the unit.
• Use proper Mains AC power cables
To avoid risks, use only the Mains AC cables recommended for this unit.
• Avoid electric shocks.
In order to avoid electrical discharges and fire hazards, do not apply electrical voltage outside the range
selected on the rear panel of the central unit.
• Ground connection.
In order to avoid electrical discharges, connect the ground terminals of all the modules to the main
ground terminal. Before connecting the inputs and outputs of this unit, make sure that all the grounding
connections are properly made.
• Before powering the unit up, make sure that it is connected to ground.
In order to avoid electrical discharges, make sure that all the grounding connections are properly made.
• Do not work in humid environments.
In order to avoid electrical discharges, always work under 90% of relative humidity (non-condensing)
and 45 ºC (113º F).
• Do not operate this unit in explosive environments.
In order to avoid risks, harm or damages, do not work in explosive environments.

Safety conditions
PRECAUTIONS AGAINST PRODUCT DAMAGE
• Work environment.
This unit is ready to be used in industrial environments complying with the directives and regulations
effective in 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 this unit in the proper place.
It is recommended, whenever possible, to install the CNC away from coolants, chemical product, blows,
etc. that could damage it.
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.
Etc.
•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.
• Avoid disturbances coming from the machine tool.
The machine-tool must have all the interference generating elements (relay coils, contactors, motors,
etc.) uncoupled.
DC relay coils. Diode type 1N4000.
AC relay coils. RC connected as close to the coils as possible with approximate values of R=220
 1 W y C=0,2 µF / 600 V.
AC motors. RC connected between phases, with values of R=300 / 6 W y C=0,47 µF / 600 V.
• Use the proper power supply.
Use an external regulated 24 Vdc power supply for the inputs and outputs.
• 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.
• Analog inputs and outputs connection.
It is recommended to connect them using shielded cables and connecting their shields (mesh) to the
corresponding pin.
• Ambient conditions.
The working temperature must be between +5 ºC and +40 ºC (41ºF and 104º F)
The storage temperature must be between -25 ºC and +70 ºC. (-13 ºF and 158 ºF)
• Monitor enclosure (CNC 8055) or central unit ( CNC 8055i)
Guarantee the required gaps between the monitor or the central unit and each wall of the enclosure.
Use a DC fan to improve enclosure ventilation.
• Power switch.
This power switch must be mounted in such a way that it is easily accessed and at a distance between
0.7 meters (27.5 inches) and 1.7 meters (5.5ft) off the floor.

Safety conditions
PROTECTIONS OF THE UNIT ITSELF (8055)
• "Axes" and "Inputs-Outputs" modules.
All the digital inputs and outputs have galvanic isolation via optocouplers between the CNC circuitry
and the outside.
They are protected by an external fast fuse (F) of 3.15 A 250V against overvoltage of the external power
supply (over 33 Vdc) and against reverse connection of the power supply.
• Monitor.
The type of protection fuse depends on the type of monitor. See identification label of the unit itself.
PROTECTIONS OF THE UNIT ITSELF (8055I)
• Central unit.
It has a 4 A 250V external fast fuse (F).
• Inputs-Outputs.
All the digital inputs and outputs have galvanic isolation via optocouplers between the CNC circuitry
and the outside.
