Safety conditions

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 complies with 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 AC power line as this equipment.
• Nearby portable transmitters (Radio-telephones, Ham radio transmitters).
• Nearby radio/TV transmitters.
• Nearby arc welding machines.
• Nearby High Voltage power lines.
• Etc.

Enclosures
The manufacturer is responsible of assuring that the enclosure involving the equipment meets all the
currently effective directives of the European Community.

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 and C=0,2 µF / 600 V.
• AC motors. RC connected between phases, with values of R=300

/ 6 W and C=0,47 µF / 600 V.

Use the proper power supply
Use an external regulated 24 Vdc power supply for the inputs and outputs.

Grounding of the power supply
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 b5 ºC and +40 ºC (41ºF and 104º F)
The storage temperature must be between -25 ºC and +70 ºC. (-13 ºF and 158 ºF)

Central unit enclosure (8055i CNC)
Make sure that the needed gap is kept between 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.
