INSTALLATION OF A SPEEDSYS300 ODS301
3.2 Installation considerations
3.2.1 Ventilation
SpeedSys300 ODS301 modules do not contain any ventilation units (fans). They therefore
rely on either natural ventilation (convection) or forced ventilation by fans in the industrial
housing, field cabinet (cubicle) or other suitable enclosure for their cooling. All require the free
flow of air in an upward direction, with air entering the module through the vents in the base
of the module and leaving it through the vents on the top of the module.
When SpeedSys300 ODS301 modules are installed in an industrial housing, cabinet or other
suitable enclosure in which natural ventilation is used, a space of at least 50 mm should be
present above and below each module, and a space of at least 10 mm should be present on
both sides of each module, and a space of at least 20 mm should be present to the front of
each module (see
).
Always observe the minimum mounting distances around SpeedSys300
ODS301 modules in order to ensure adequate spacing is provided to allow
for sufficient cooling.
Failure to adhere to this requirement could cause overheating, which as a
consequence could affect the correct operation of the system.
