Risk of injury!

Bring the bus system into a safe, de-energized state before starting installation, disassembly or wiring of

the devices!

4.1.4.1

Control cabinet / terminal box

For operation the EL9930 terminals must be installed in a control cabinet or terminal box with a minimum

protection class of IP54 according to IEC 60529.

4.1.4.2

Installation position and minimum distances

For the prescribed installation position the mounting rail is installed horizontally and the mating surfaces of

the EL/KL terminals point toward the front (see illustration below). The terminals are ventilated from below,

which enables optimum cooling of the electronics through convection. The direction indication "down"

corresponds to the direction of positive acceleration due to gravity.

Fig. 6: Installation position and minimum distances

In order to ensure optimum convection cooling, the distances to neighboring devices and to control cabinet

walls must not be smaller than those shown in the diagram.
