3. System implementation

3.1 Power supply

It is important for system integration to make sure that power supply for ARE i2.0x LF is absolutely stable and clean with no
noise. It is recommended to use linear power supplies rather than switching power supplies. All other applications benefit
from this as well.

3.2 Grounding

Please make absolutely sure that ARE i2.0x LF is properly grounded. This ensures proper functionality of the entire system
comprising of ARE i2.0x LF and AAN Xi9F. Please see chapter 2.1.4 for details on grounding.
Grounding can be achieved by grounding DIN hat rail, as clamp on backside of ARE i2.0x LF is connected to ground.
Alternatively, the grounding pin on the frontside of ARE i2.0x LF can be used to achieve this.

3.3 Mounting on metal

ARE i2.0x LF is typically mounted on a metal DIN hat rail in a metal electrical cabinet. There is no influence of metal on
performance of ARE i2.0x LF and therefore nothing to watch out for.
It is recommended to mount AAN Xi9F onto a non-conductive surface. However, AAAN Xi9F is designed to work when
mounted on metal as well. There is a slight decrease in read/write range when compared to mounting on non-conductive
surfaces, but in most cases the read/write range will still be plenty for the application.

3.4 Frequency converters

Frequency converters used in electronic motors are a source of significant EMV noise. Make sure to stay away as far as
possible from those frequency converters when designing spots where ARE i2.0x LF to be used. Noise from frequency
converters significantly reduce read range of ARE i2.0x LF.
