Installation Guidelines
-
Mounting: Mount the module horizontally on a standard 35 mm DIN rail (EN 60715) within a secure IP54-rated control enclosure.
-
Ventilation: Ensure a minimum clearance of 30 mm above and below the device to permit adequate natural convection cooling in fanless systems.
-
Grounding: Connect the integrated PE contact on the DIN rail or backplane terminal directly to the central functional earth terminal of the control cabinet.
-
Power Cabling: Use copper conductors rated for at least 75 Celsius and properly sized to meet the 24 V DC (-15% / +20%) supply tolerance requirements.
