2.2 Notes about usage
Industrial applications
The HMI device is designed for industrial applications. It conforms to the following standards:
● Emission requirements, EN 61000-6-4:2007
● Immunity requirements, DIN EN 61000-6-2:2005
Use in residential areas
Note
The HMI device is not suitable for operation in residential areas. Operation of an HMI device
in residential areas can have a negative impact on radio and TV reception.
If you are to use the HMI device in a residential area, you must ensure Limit Class B
conforming to EN 55011 for radio frequency interference.
One suitable measure for achieving the required RF interference level for limit class B is:
● To use filters in electrical supply lines
Individual acceptance is also required.
Mechanical and climatic conditions of use
Check the mechanical and climatic environmental conditions according to the following
sections:
● Ambient conditions during operation (Page 82)
● Ambient conditions and degree of protection connection box (Page 83)
NOTICE
Climatic factors at the place of use
Fluctuations in temperature cause condensation inside the device. The device is exposed
to heat and to the cold even when not in operation.
• Do not expose the device to extreme temperature fluctuations.
The device has a pressure compensation valve to provide additional protection in the event
of temperature fluctuations. The pressure compensation valve contains a membrane which
helps to reduce the level of moisture in the device.
Please note the following:
• The valve must always be freely ventilated and must be protected from dirt.
• The device is always supplied with power so that the waste heat from the electronics
26
system keeps the interior temperature slightly higher than the exterior temperature. This
reduces the likelihood of malfunctions caused by condensation and creates a sufficient
vapor pressure for ventilation.
