3.5 Damage due to overheating
• All C6 P34 Box systems are designed for vertical position mounting.
• A inclined installation reduces the thermal convection by C6 P34 BOX and the ma-
ximum permissible ambient temperature for operation. Please contact KEB for de-
tails. C6 P34 BOX may otherwise be damaged and its certifications and warranty
will be void.
• The ambient temperature must be between 0°C to +50°C measured 5 cm from all
openings of the system where there is air entrance.
• Provide space around the system for air recirculation and heat exchange. Keep at
least 7 cm of space behind (z) and to the sides (x) of the PC cell, while above (y)
and below (y) the PC cell are needed 10cm.
• Make sure that the grids on PC cell for air exchange are free from objects and
cables and far from other obstacles to the air flow.
• For example, when the system is installed in cabinets with no airconditioning, it is
necessary to ensure the exchange of air from outside through at least two openings:
• An opening should be placed under the PC cell, it must be large enough to allow the
correct air flow from outside that is required to be within the limits specified in the
section on temperature.
•
A sufficient size opening must be positioned above the PC cell to allow the outflow
of the hot air outside.
• It is possible to use one or more lateral openings instead of the two above menti-
oned, subject to the condition that their vertical dimension is long enough to ensure
the heat required exchange.
• When the system is placed in air conditioned cabinets, the conditioning system must
provide the air circulation with proper ventilation.
• When the system is installed in closed cabinets, it is still necessary to ensure that
the maximum ambient temperature is +50°C.
• Mounting angle:
a) The system is intended to be mounted vertically.
b) For inclinations of more than 10° and up to 20° is necessary to decrease the
maximum operating temperature of 5°C.
c) For other installation modes contact KEB.
For installation in control cabinets and, in particular, in closed containers, make
sure the recommended ambient temperature is maintained.
