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
the enduring 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
The degrees of protection of the HMI device can only be guaranteed if the following
requirements are met:
●
Material thickness at the mounting cutout for IP65 degree of protection, or for
enclosure type 4X/type 12 (indoor use only): 2 mm to 6 mm
●
Permissible deviation from plane at the mounting cutout: ≤
0.5 mm
This condition must be fulfilled for the mounted HMI device.
●
Permissible surface roughness in the area of the seal: ≤
120 µm (R
z
120)
