4 CENTRAL UNIT (CPU) ENCLOSURE (Q7-A PLATFORM).
The enclosure must be designed to ensure an ambient temperature of 45 ºC (113 ºF) and
while the unit is running, the inside temperature of the CNC must not exceed 60 ºC (140 ºF).
The inside temperature of the CNC may be monitored from the diagnosis mode (see the
operating manual).
Enclosure requirements.
The enclosure must meet the following requirements.
• The protection degree of the enclosure must be IP54.
• The dissipation surface of the enclosure must be enough to evacuate (by convection)
the heat generated inside. Dissipation surfaces are all the surfaces of the enclosure
except the front and bottom.
• The enclosure must respect the minimum distances recommended between the
enclosure walls and the central unit to let the air flow and improve heat dissipation.
Minimum enclosure dimensions.
If necessary, increase the dimensions of the enclosure; NEVER use smaller dimensions than
the recommended minimum values.
C70-10K.
C70-15.
C70-15AT.
Power dissipated by the CNC.
To calculate the dissipated power, all the elements that are inside the enclosure must be
taken into account. The central unit dissipates 24 W.
To meet the previous requirements, Fagor recommends the following.
• The enclosure must not have any ventilation holes, because they could let dust or other substances
in.
• To improve heat dissipation, install a fan inside the enclosure for air circulation.
Before building an enclosure with glass fiber u another poor heat dissipating material, contact Fagor
Automation.
