The test generator necessary to perform direct and indirect application of discharges 
to the EUT in the following manner: 
a. Contact discharge was applied to conductive surfaces and coupling planes of the 
EUT. 

During the test, it was performed with single discharges. For the single discharge 
time 
between successive single discharges was at least 1 second. The EUT shall be 
exposed to at least 200 discharges, 100 each at negative and positive polarity, at a 
minimum of four test points. One of the test points shall be subjected to at least 50 
indirect discharges to the center of the front edge of the horizontal coupling plane. 
The remaining three test points shall each receive at least 50 direct contact 
discharges. 
If no direct contact test points are available, then at least 200 indirect discharges 
shall be applied in the indirect mode. Test shall be performed at a maximum 
repetition rate of one discharge per second.   
The selected point, which was performed with electrostatic discharge, please 
refers to the “Photo(s) shown the location(s) of ESD evaluated”. 
Vertical Coupling Plane (VCP): 
The coupling plane, of dimensions 0.5m x 0.5m, is placed parallel to, and 
positioned at a distance 0.1m from, the EUT, with the Discharge Electrode 
touching the coupling plane. 
The four faces of the EUT will be performed with electrostatic discharge. 
Horizontal Coupling Plane (HCP): 
The coupling plane is placed under to the EUT. The generator shall be positioned 
vertically at a distance of 0.1m from the EUT, with the Discharge Electrode 
touching the coupling plane. The four faces of the EUT will be performed with 
electrostatic discharge. 

b. Air discharges at insulation surfaces of the EUT. 

It was at least ten single discharges with positive and negative at the same selected 
point. 

c. For the actual test configuration, please refer to the related Item –EUT Test Photos.

Note: 
TABLE-TOP EQUIPMENT 
The configuration consisted of a wooden table 0.8 meters high standing on the 
Ground Reference Plane. The GRP consisted of a sheet of aluminum at least 0.25mm 
thick, and 2.5 meters square connected to the protective grounding system. A 
Horizontal Coupling Plane (1.6m x 0.8m) was placed on the table and attached to the 
GRP by means of a cable with 940k total impedance. The equipment under test, was 
installed in a representative system as described in section 7 of IEC 61000-4-2, and its 
cables were placed on the HCP and isolated by an insulating support of 0.5mm 
thickness. A distance of1-meter minimum was provided between the EUT and the 
walls of the laboratory and any other metallic structure. 
FLOOR-STANDING EQUIPMENT 
The equipment under test was installed in a representative system as described in 
section 7 of IEC 61000-4-2, and its cables were isolated from the Ground Reference 
Plane by an insulating support of 0.1-meter thickness. The GRP consisted of a sheet 
of aluminum that is at least 0.25mm thick, and 2.5meters square connected to the 
protective grounding system and extended at least 0.5 meters from the EUT on all 
sides.
