NOTICE
Avoid dewing
If the HMI device is subjected to low temperatures or extreme fluctuations in temperature
during transportation, moisture could occur on or inside the HMI device. Dewing can occur.
This can cause malfunctions.
The HMI device must have acquired room temperature before it is put into operation. Do
not expose the HMI device to direct radiation from a heater in order to warm it up. If there is
condensation, wait approximately 4 hours until the HMI device has dried completely before
switching it on.
Proper transport and storage, installation and assembly as well as careful operation and
maintenance are required to ensure trouble-free and safe operation of the HMI device.
The warranty for the HMI device will be deemed void if these stipulations are not heeded.
