Prescribed installation position

Constraints regarding installation position and operating temperature range
When installing the terminals ensure that an adequate spacing is maintained between other components
above and below the terminal in order to guarantee adequate ventilation!
Prescribed installation position
The prescribed 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.
Fig. 28: Recommended minimum distances for standard installation position
Compliance with the distances shown in Fig. Recommended distances for standard installation position is
strongly recommended.
