12.6 Installation
Mounting location The device is designed for installation on 35 mm (1.38 in) DIN rails in accordance with IEC
60715 (TH35).
NOTICE
‣
When using in hazardous areas, the limit values of the certificates and approvals must
be observed.
For information on ambient conditions, see the "Technical data" section.
Installing a DIN rail device The device can be installed in any position (horizontal or vertical) on the DIN rail without
lateral clearance from neighboring devices. No tools are required for installation. The use
of end brackets (type "WEW 35/1" or similar) on the DIN rail is recommended to fix the
device.
If several devices are installed side by side, it is important to ensure that the
maximum side wall temperature of 85 °C (185 °F) is not exceeded. If this cannot be
guaranteed, mount the devices at a distance from one another or ensure sufficient
cooling.
