Make sure that there will be enough volume for air changes inside the control cab-
inet, etc.
The specified clearance around the XH-303 HMI Web Panel is: a, b, c ≧ 30 mm
(1.18")
l
If you will be installing the XH-303 HMI Web Panel in complex systems together
with other assemblies, you must ensure that there will be enough air circulation in
order to prevent overheating.
Ambient temperature with natural convection: ϑ 0°C (32°F) ≦ T ≦ 50°C (122°F)
The panel builder is responsible for the temperature rise calculation. Eaton will
provide heat dissipation data for the XH-303 as necessary for design verification
in accordance with IEC EN 61439.
3.1.1.3 Criteria for the installation position
The XH-303 are intended to be flush mounted in control cabinets, control panels, or
control consoles.
l
XH-303 units can be installed in landscape or portrait mode.
l
If no forced ventilation is being used, the device must not be mounted at an angle
⍺ of more than ±α ≦ 45° relative to its fully vertical position.
An angle ⍺ greater than 10° for the XH-303-15-A10-A00-2B is only permissible with
a reduced maximum ambient temperature of 45 °C.
