4 Installation
Mount the unit in a control cabinet with a protection rating of at least IP 54 to
ensure protection against accidental contact with dangerous contact voltages and
against atmospheric influence� The control cabinet should be installed in accor-
dance with local and national rules and regulations�
Mount the unit on a DIN rail� Mount it vertically and leave enough space between
the unit and the top and bottom of the control cabinet (to enable air circulation to
avoid excessive heating)�
At maximum ambient temperature, additional convection cooling is necessary�
Prevent the penetration of conductive or other dirt during installation and wiring�
