NOTICE
Installation of the HMI device
Always mount the HMI device according to the instructions in this manual.
Risk of guaranteed level of protection not being met
If the mounting seal is damaged or protrudes beyond the HMI device, the level of protection
is not ensured.
Check the fit of the mounting seal.
Note
Tighten the threaded pins of the mounting clamps until the HMI device is flush with the
surface of the control cabinet. Alternatively, tighten the mounting clamps using a maximum
torque of 0.2 Nm.
Proceed as follows:
1. Check that the mounting seal is fitted on the HMI device.
Do not install the mounting seal turned inside out. This may cause leaks in
the mounting cutout.
2. Insert the HMI device into the mounting cutout from the front.
3. Insert a mounting clamp into the cutout provided on the HMI device.
