3.3.4 Power supply and wiring requirments
3.3.4.1 Wiring requirements
In industrial environment, correct ground connection is the main method for noise
suppression and interference prevention, and the main interference of the equipment circuit is
sourced from the unreasonable ground wire. Therefore, it is import to correctly handle the ground
connection of the circuit in order to ensure the normal operation and the read/write success rate of
the reader.
Under normal circumstances, the power voltage of the reader equipment is 24V, belonging to the
low voltage, so the power wire and 485 power wire of the reader should be connected to the weak
current trunking during wiring, and the trunking must have standard ground connection (“0”
electric potential). If the trunking and the shielding layer cannot be connected to the standard
“0” electric potential, the power supply should follow relevant regulation in 3.3.4.2.
3.3.4.2 Power supply requirements
In industrial environment, electromagnetic interference has such characteristics as complexity,
variability and uncontrollability and usually enters the reader through power supply coupling to
generate adverse impact and cause abnormal operation of the reader, so power interference is one
of the most harmful main interference sources. In order to eliminate such conduction interference,
it is suggested to provide independent power supply or set a filter at the power terminal for RFID.
