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.
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 (See chapter 2).
Ambient conditions
The working temperature must be between +5° C and +45° C (41ºF and 113º F)
The storage temperature must be between -25° C and 70° C. (-13º F and 158º F)
Monitor enclosure
Assure that the Monitor is installed at the distances indicated in chapter 1 from the walls
of the enclosure.
Use a DC fan to improve enclosure ventilation.
Main AC Power Switch
This switch must be easy to access and at a distance between 0.7 m (27.5 inches) and
1.7 m (5.6 ft) off the floor.
Protections of the unit itself
It carries two fast fuses of 3.15 Amp./ 250V. to protect the mains AC input.
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 Amp./ 250V. against over voltage
and reverse connection of the power supply.
The type of fuse depends on the type of monitor. See the identification label of the unit.
