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 equivalent) 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 the individual devices of 80 °C (176 °F) is not
exceeded. If this cannot be guaranteed, mount the devices at a distance from one
another or ensure sufficient cooling.
