ā¢ Mounting location
The control has the degree of protection IP 20 and is thus intended for use in a closed control
cabinet or control box (terminal box) of the degree of protection IP 54 (acc. to DIN EN 60529)
or higher. The control cabinet has to be provided with sufļ¬cient stability and rigidity and has to
comply with the requirement to impede ļ¬re spreading (acc. to UL 61010-1, 61010-2-201).
ā¢
Support rail
Mount the control on an electrically conductive 35 mm standard support rail. Its connection to the
functional earth is sufļ¬cient. Only use a support rail with an design height of 7.5 mm (corresponds
to TH 35-7.5 acc. to EN 60715).
The fastening distance of the support rails may not exceed 200 mm. This distance is required to
ensure stability while mounting and dismounting the control.

ā¢ Mounting position
To ensure air cooling in the device by convection, mount the control only vertically on a horizontal
support rail as shown in the following ļ¬gure.
In the shown mounting position, the natural convection supports the forced cooling air ļ¬ow. Heat
pockets can thus not be caused in the device.
