Preparing The Mounting Cutout - Siemens MTP700 Unified Comfort Hygienic Compact Operating Instructions

Preparing the mounting cutout

Note
Stability of the mounting cutout
The material in the area of the mounting cutout must provide sufficient strength to
guarantee lasting and safe mounting of the HMI device.
To achieve the degrees of protection described below, it must be ensured that deformation of
the material cannot occur due to the force of the mounting clips or operation of the device.
Degrees of protection and installation area
Correct installation and the degrees of protection of the HMI device (Page 53) are only
guaranteed if the following requirements are met:
• Material thickness at the mounting cutout: 1 mm to 5 mm
• Permissible deviation from plane at the mounting cutout: ≤ 0.5 mm
This condition must also be fulfilled for the mounted HMI device.
• Surface roughness of the surface coming in contact with the device gasket: Ra ≤ 3.2 µm
and Rz ≤ 12 µm
For hygiene reasons, we recommend mounting the device on polished, brushed or
smooth surfaces with a roughness value Ra < 0.8 µm and Rz < 6.3 µm (polish with 240
grain or finer). Only then can antimicrobial cleaning of the device and its environment be
guaranteed.
• The installation area is dry and free from contamination, such as dust or lubricant.
Compatibility of the mounting cutout to other HMI devices
The hygienic HMI devices are mounting-compatible with standard SIMATIC Unified Comfort
Panels, Industrial PCs, Industrial Flat Panels and Industrial Thin Clients with identical display
diagonals.
Note that although the dimensions for the mounting cutout are the same, the device depth
and the front dimensions of the hygienic HMI devices may differ from the compatible
devices.
In addition, the following installation compatibility with the predecessor devices applies:
