Minimum Clearances
Maintain minimum clearance of 2” from enclosure walls, wires and other adjacent devices on all sides for
adequate ventilation. Plan for adequate space around the product and inside the enclosure for ventilation and
cabling. Take into consideration the heat produced by other devices in the enclosure. The operating temperature
for this product is between 0° to 50°C. Care should be taken in-order to maintain the ambient temperature around
the Web HMI within this range.
Mounting Web HMI Products
Web HMI series products must be installed on the front panel, using the clamp accessories shipped with the
product. Before mounting, make sure that sealing gasket is properly positioned. This gasket forms a compression
type of seal. Do not use sealing compounds. Place the unit in the panel cutout and tighten the mounting screws
evenly (torque 0.4Nm) to maintain water and dust resistance.
