Installation
7.3.1

Control cabinet / terminal box

The TwinSAFE terminals must be installed in a control cabinet or terminal box with IP54 protection class
according to IEC 60529 as a minimum.
7.3.2

Installation position and minimum distances

Fig. 6: Installation position and minimum distances
Mount the mounting rail horizontally for the specified installation position. The connection surfaces of the EL
terminals or KL terminals must face forwards. This can be seen from the illustration.
The components are ventilated from bottom to top, which enables optimum cooling of the electronics by
convection ventilation. The direction specification "down" corresponds to the direction of the positive
acceleration due to gravity.
Observe minimum distances
Maintain the distances to neighboring devices and control cabinet walls specified in the figure. This is the
only way to ensure optimum convection cooling.
If sufficient convection cooling is not ensured, the devices may overheat and be damaged.
