2.7.4 Operating
environment
The environmental license plate requirements for the correct functioning of the
instrument are:
↘ Operating temperature: 045°C
↘ Storage temperature: 050°C
↘ Humidity: 85% non-condensing
2.7.5 Electromagnetic
compatibility
The boards of DLC
NET
series are equipped with appropriate filtration in order to
meet the EMC requirements that the Directive 2014/34/EU requires.
To improve immunity to radiated interference, emitted by a radio transmitter,
it is important to:
↘ Use shielded cables with shielding connected to earth at 100% for
connections to the card.
↘ In the presence of earth resistance values low, connect to ground
both sides of the screen to improve the effectiveness of the
shielding.
