Installation positions

Constraints regarding installation position and operating temperature range

Please refer to the technical data for a terminal to ascertain whether any restrictions regarding the installa-

tion position and/or the operating temperature range have been specified. When installing high power dissi-

pation terminals ensure that an adequate spacing is maintained between other components above and be-

low 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
