3.2.2 Preparing for installation
Select the mounting location of the HMI device
Points to observe when selecting the mounting location:
● Position the HMI device so that it is not subjected to direct sunlight.
● Position the HMI device such that it is ergonomically accessible for the user.
Choose a suitable mounting height.
● Ensure that the air vents of the HMI device are not covered as a result of the mounting.
● Note the permissible mounting positions.
NOTICE
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.
The force of the clamps or operation of the device may not lead to deformation of the
material in order to achieve the degrees of protection described below.
Degrees of protection
The protection ratings are only ensured if the mounting cutout conforms to the following:
● 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
● Permitted 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)
A clamping frame is additionally available for mounting the MP 377 12" Touch to panels with
a material thickness < 2 mm at the mounting cutout. The frame enables IP65 degree of
protection or enclosure type 4X/type 12 to be achieved.
