Installation positions

Constraints regarding installation position and operating temperature range
Please refer to the technical data for a terminal to ascertain whether any restrictions re-
garding the installation position and/or the operating temperature range have been speci-
Attention
fied. When installing high power dissipation terminals ensure that an adequate spacing is
maintained between other components above and below the terminal in order to guarantee
adequate ventilation!
Optimum installation position (standard)
The optimum installation position requires the mounting rail to be installed horizontally and the connection
surfaces of the EL/KL terminals to face forward (see Fig. "Recommended distances for standard installation
position"). The terminals are ventilated from below, which enables optimum cooling of the electronics through
convection. "From below" is relative to the acceleration of gravity.

Compliance with the distances shown in Fig. "Recommended distances for standard installation position" is
recommended.
