performance of electronic equipment.Electromagnetic interference not only

affects the normal operation of electronic equipment, but even causes damage to

certain components in electronic equipment. With the increase in automation, the

arrangement of electrical and electronic equipment becomes more complicated,

and the risk of interaction between devices is increased.Electromagnetic

interference mainly consists of three parts: interference source, coupling path

and interference receiver. When applying the implementation plan in the field, it

is necessary to identify the most frequent sources of interference and the possible

coupling paths that exist, so as to take corresponding measures to reduce the risk

of electromagnetic interference and ensure the normal operation of the

equipment.

In order to ensure electromagnetic compatibility enough, the following rules

must be observed:

1、The device is shielded by the outer casing. The reader-related equipment

is installed in the cabinet and grounded through the rack to shield the external

magnetic field.

2、The equipment is well grounded.Good grounding can ensure the clean

power supply of the equipment, and on the other hand, it can prevent the

excessive impact voltage from being damaged when the equipment fails, and

damage the reader.

3、Cable shielding. For sites with complex electromagnetic environments,

shielded communication cables must be used to avoid interference signals being

coupled to the cables.

4、Signal and line filtering. Install the filter in the power inlet or cabinet

inlet direction to avoid interference from the power source into the device.

3.5.2 Power supply and wiring requirements

In an industrial environment, a major source of interference in equipment circuits is

caused by unreasonable ground lines. Therefore, proper grounding is an important

method to suppress noise and prevent interference, and is the key to ensure the normal

operation and read/write success rate of the reader.

Under normal circumstances, the reader device power supply voltage is 24V, which is

a weak current. When wiring, connect the power supply line of the reader and the 485

power supply line from the weak current slot, and the cable slot must be connected to

the standard earth（“0”Level）.

Note: If the grounding of the slot and shield is not guaranteed to be

the standard "0" potential, you need to provide independent power

for the RFID or add a filter to the power supply.
