Installation of EJ modules
EJ3255 23 Version: 1.1
4.3.2 Installation positions
NOTE
Constraints regarding installation position and operating temperature range
Please refer to the technical data [
}
16] for the installed components to ascertain whether any restrictions
regarding the mounting position and/or the operating temperature range have been specified. During instal-
lation of modules with increased thermal dissipation, ensure adequate distance above and below the mod-
ules to other components in order to ensure adequate ventilation of the modules during operation!
The standard installation position is recommended. If a different installation position is used, check whether
additional ventilation measures are required.
Ensure that the specified conditions (see Technical data) are adhered to!
Optimum installation position (standard)
For the optimum installation position the signal distribution board is installed horizontally, and the fronts of
the EJ modules face forward (see Fig.
Recommended distances for standard installation position ). The
modules are ventilated from below, which enables optimum cooling of the electronics through convection.
“From below” is relative to the acceleration of gravity.
Fig. 14: Recommended distances for standard installation position
Compliance with the distances shown in Fig. Recommended distances for standard installation position is
recommend. The recommended minimum distances should not be regarded as restricted areas for other
components. The customer is responsible for verifying compliance with the environmental conditions
described in the technical data. Additional cooling measures must be provided, if required.
