5.1 Electrostatic discharge immunity
The test method is shown in G/T126.2.
ESD is only applied to those points that can be touched by people in normal use. Unless otherwise specified, FST) test is not allowed to evaluate the non-electrical protection points that are in place for maintenance purposes. If the manufacturer has requirements for equipment protection, it must be added in the obvious positions of the equipment and indicated in the equipment documentation. 5.2 Electrical fast-changing pulse group immunity test method GB/T17626.4.

5.3.1 Outdoor signal port
See G17626.5 for the test method.
The dust collector should be connected to the optical port of the device through the network. This port is usually only connected to the surge (impact) generator. After the test, all other ports (not connected to the safety device) should be used. After the test, the device should be disconnected from the tested port and check whether the tested port meets the performance requirements: 5.3.If the coupling/maximum coupling network specified in GB/T17626.5 does not meet the requirements for the signal received by a certain bit rate port, the test method in Appendix A shall be used. This method is suitable for non-shielded 4-wire balanced power supply with D: power supply and uses a terminal type with a bit rate less than or equal to amlit. The test for shielded terminal transmission is not applicable to the network specified in GB/T17626.5 for ports connected to multiple cores, and the network specified in GB/T17626.5 shall be used. If the normal function of the conductor cannot be achieved due to the influence of (jiang), the relevant anti-bend deformation material is not required. 5
