Product Overview
This section of the manual provides an overview of Web HMI series products, its front and back view, installation
details, dimensional details, mounting method and details.
Installation of the Web HMI products
Web HMI series products are designed for front panel mounting. Before installing the products, user should
review the panel guidelines, panel cutout dimensions, product dimensions and minimum clearances.
Panel Guidelines
The panel must be at least 2mm (12 gauge), in order to provide the required support and proper sealing against
water and dust. The panel surface must be flat, devoid of any imperfection, to maintain adequate seal and IP
rating. The maximum panel thickness on which this HMI can be mounted is 6mm (±0.2mm).

ATTENTION
ATTENTION: Panel cutout
▪Before cutting out the panel, disconnect all electrical power from the panel.
▪Make sure that the area surrounding the panel cutout is clear.
▪Make sure that metal cutting chips do not enter any other component, already
installed in the panel.
Product Dimensions
This section of the manual provides dimensional details of Web HMI series products. All the dimensions shown
below are measured in mm.

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.
ATTENTION
ATTENTION: Mounting Web HMI on Panel
▪Do not push directly on the LCD display of the HMI when placing the unit into the
panel as it may damage the display. Push on the bezel or the border of the LCD
display.
Connecting Power
Web HMI series require 24VDC to operate. Follow the steps mentioned below to connect a power supply to the
device:
▪Make sure that terminal is not connected to power source.
▪Secure the 24VDC power wires.
▪Secure the functional earth ground wire to the functional earth ground terminal screw on terminal block.
▪Apply 24VDC power to the terminal.
Grounding
The optimum method for grounding electronic equipment is to ground it separately from other high-power systems
and to ground more than one unit of electronic equipment with a single-point ground. Following marked terminal is
provided with the unit for grounding:
