3. INTRODUCTION
We thank you very much for your purchase of ESS-801GL.
The Model ESS-801GL is manufactured for test set-up for floor-standing equipment in
accordance with IEC 61000-4-2. The ESS-801GL can also be used for usual electrostatic
discharge tests or impulse noise tests.
In order to obtain the highest performance from ESS-801GL , thoroughly understand the
contents of this manual and use as ready reference for operation.
Features
1. It can be used for conducting tests on IEC 61000-4-2 in combination with our Electrostatic
Discharge Simulators.
2. Wooden insulation pallet minimizes the loss of energy produced by the simulator and the
loss of high-frequency electromagnetic field, resulting in excellent determination and
reproducibility.
3. It can be maintained the distance at 0.1m between vertical coupling plane and EUT by
dabbing at the floor equipment.

8. Operation (for Reference)
Electrostatic dischar e test based on EN/IEC 61000-4-2 (EUT: Floor-standin devices)
Fi ure 2. Example Test Layout
1. Lay a round plane in the test room to serve as the round reference for the test.
Caution
Althou h the EN/IEC 61000-4-2 standard does not specify where in the test room to lay
the round plane, it does specify that, when positioned on top of the insulatin platform,
the equipment under test (EUT) must be at least 0.8m from the walls or any metallic
objects.
*
As the len th of the round plane is 1.8m in its lon itudinal direction, if it is laid in a
corner of the test room the distance from the wall mi ht be less than 0.8m in the case of a
lar e EUT.
* The requirement for the distance from walls was changed to “0.8m or more” in Edition 2.0 of the
EN/IEC 61000-4-2 standard. The requirement in Edition 1.02 and earlier was “1.0m or more”.
2. Usin an appropriate cable, connect the round plane to the test room’s protective round
terminal. To connect the round cable to the round plane, use the boss hole (M4) or the M3
screw holes used for interconnection.
If the test room does not have a protective ground terminal, have one installed by a
qualified technician. Never use gas, water, or other internal piping as a substitute for a
protective ground terminal because of the risk of fire or explosion, and because of the
possibility that these pipes may not be earthed.

3. Place the insulatin platform on top of the round plane, confirm that the platform does not
wobble, then place the EUT on top of the platform. Do not lay anythin on top of the
insulatin platform.
4. Move the assembled floor-standin vertical couplin plate onto the round plane, loosen the
knobs for adjustin the vertical and horizontal clamp position, and slide the vertical couplin
plate until plate A ( uide plate) comes into contact with the external surface of the EUT for
which the indirect dischar e test is to be performed. After settin in the location where the
indirect dischar e is to be applied, ti hten the two knobs on the clamp to secure the vertical
couplin plate in position. This ensures that the distance between the EUT and vertical
couplin plate is kept at 0.1m.
5. Usin an M4 bolt (with washer), attach the dischar e resistance cable to the vertical couplin
plate. Usin an M4 bolt (with washer), connect the other end of the dischar e resistance cable
to a boss hole (M4) on the round plane. It does not matter which end of the dischar e
resistance cable is connected to the plate and which to the round plane.
6. If required, plu the AC power cable from the EUT into an isolatin transformer (use of a
NoiseKen NCT Series transformer is recommended).
☆ Althou h the EN/IEC 61000-4-2 standard does not allow use of an isolatin transformer,
the Japanese JIS C 61000-4-2 standard stipulates how to connect an isolatin transformer
when the EUT specifications and Japanese power supply conditions make this necessary.
7. Place the electrostatic tester on the round plane. Placin the tester on the insulatin
platform is not permitted.
8. Connect the round cable from the dischar e un to the round plane. The boss holes (M4) on
the round plane can be used as connection terminals. In some cases, the size of the EUT or
its position relative to the electrostatic tester will prevent the round cable from reachin a
boss hole (M4), or mean that the dischar e un cannot be brou ht close to the EUT when the
round cable is connected. In situations such as this, add a new round terminal at a
convenient location on the round plane usin a bolt and braided wire.
Also, attach the center adapter to the conical dischar e tip of the dischar e un, and insert
the vertical couplin plate into the roove at the tip to use as a uide for maintainin the
indirect dischar e position.

Notes
Even in the case of comparatively lar e floor-standin EUTs, if the EUT lacks a round cable
due to use of battery power, for example, the application of electrostatic dischar es causes EUT
itself to leave a residual char e, reduce the effectiveness of subsequent dischar es and we will
lose the validity of the test result.
To avoid this problem, the EN/IEC 61000-4-2 standard stipulates that any residual char e on
the EUT be neutralized after each application of electrostatic dischar e, and the supplied
dischar e resistance cable can also be used to neutralize
*
any residual char e on the EUT.
In the case of an EUT with sites for applyin an electrostatic dischar e such as metal
connectors or shells on a case made of plastic or other non-conductive material, it is permitted
to leave a neutralizin cable connected to the point of application while dischar es are applied.
In this Case, there is a stipulated orientation for connectin this cable. The supplied dischar e
resistance cable has two 470 kΩ resistors. If usin this cable, connect the resistor contained in
the square pillar case to the point of application, while for the resistor contained in the round
pillar case, connect the crimped terminal at the end of the cable to the horizontal couplin
plate.
If the test results are different dependin on the method used to neutralize residual char e,
use the results of tests in which the char e is neutralized between each dischar e application.
* A special-purpose neutralizing brush (Model 05-00125A) designed for removing residual charge
from EUTs is available as an option.
