CAUTION

Interference of the unit with other equipment

Be sure that this electrosurgical unit is not used adjacent to or stacked with other equipment
(other than the components of this electrosurgical unit or system) to avoid electromagnetic
interference.

Before use, thoroughly confirm the compatibility of all equipment.

To ensure electrical safety, the electrosurgical unit should not be used in conjunction with:

 Electrical equipment whose safety against leakage current is not guaranteed.
 Electrosurgical equipment whose safety in combined use is not guaranteed.

The electrosurgical generator complies with the electromagnetic compatibility (EMC) standard.
Nevertheless, when the electrosurgical generator is active it may disturb neighboring electronic
equipment. If an auxiliary computer system is in use together with the electrosurgical generator
and endoscopic imaging techniques, the image on the monitor might freeze or blackout. Follow

the instructions in “Electromagnetic Compatibility (EMC) information” in the Appendix of the

instruction for use regarding electromagnetic ambient conditions.

Never loop the cords (active cord, bipolar cord, neutral electrode cord) or bundle cords together
with cords belonging to other medical equipment. The high frequency signals or spark discharge
noise generated by the unit may interfere with the operation of other medical equipment.

Do not use the electrosurgical unit in a location exposed to strong electromagnetic radiation
(microwave or short-wave medical treatment equipment, Magnetic Resonance Imaging, radio or
mobile phone equipment). Electrosurgical unit malfunction can occur.

Accessories

WARNING

Mechanical stress

Do not apply excessive bending, straining, or squeezing force to any cords. It may cause
malfunction.

CAUTION

Non-compatible accessories and accessory damage

The electrosurgical generator shall only be used with compatible accessories. When connecting
accessories (cords, electrodes, HF instruments) avoid output settings where the maximum
output voltage of the electrosurgical generator may exceed the rated accessory voltage (refer to
“Mode characteristics”, “Output characteristics” in the Appendix of the instruction for use, and the
instruction manual of the accessory). For a list of compatible neutral electrodes, refer to
“Specifications” in the Appendix of the instruction for use.

Before use, the electrosurgical unit and accessories must be examined for damage. All
communication cables and its plugs must be free of scratches and cracks. Cables and
accessories with damaged insulation or connections must not be used.

Electric shock

WARNING

Grounding failure

To prevent the risk of electric shock, the housing of the electrosurgical unit must be grounded.
Always connect the power cord plug to a properly grounded wall outlet. Do not use a
3-pin / 2-pin adapter, as it can impair safe operation of the unit.

WARNING

User shock

To prevent user shock, malfunction and damage of the electrosurgical unit, keep liquids away
from all electrical equipment.

When taking measurements or troubleshooting of the electrosurgical unit, take appropriate
precautions, such as using isolated tools and equipment, using the “one hand rule,” etc.

CAUTION

Injury during servicing

When the housing is opened, there is a danger of electric shock. The unit must only be serviced
by authorized technicians.

Burns

WARNING

User

The maximum output voltage characteristics of the electrosurgical generator are shown in the

diagrams in “Output characteristics” in the Appendix of the instruction for use. When setting the

power level, first set it to a low level and increase it gradually. If the output is initially set to a high
level, the electrode’s insulation may be damaged and cause user and / or patient burns.
However, certain modes may present an unacceptable risk at low output power settings. For
example, with the PulseCut fast mode or PulseCut slow mode, the risk of an excessive thermal
effect rises if the output power setting is too low. Therefore, it is recommended that you perform
basic testing before using the electrosurgical generator. If the instruction manual of the HF
instrument to be used stipulate a rated voltage, the output should be set so that it does not
exceed that voltage.

High frequency, high voltage signals that can cause severe burns are present in the
monopolar / bipolar sockets described in this maintenance manual. Take appropriate precautions
when testing and troubleshooting this area of the electrosurgical unit.

ESG-400

2 Features

The ESG-400 is a reusable, non-sterile electrosurgical generator with different mono- and bipolar cutting and
coagulation modes. The maximum output power is 320 W.

On the front side it features a touch screen display that displays the connection status of accessories and
peripherals connected to the electrosurgical generator. It is also used to show and modify the output settings
(e.g. mode, output power, effect) as well as to control other functions (e.g. save settings).

In addition the ESG-400 has a bipolar socket, two monopolar sockets, a neutral electrode socket, and a
universal socket to connect applicators with instrument recognition. The power switch turns the generator on
and off.

Two contact quality indicators (one for split and one for non-split electrodes) are green illuminated if neutral
electrodes are correctly connected. Three additional push buttons allow recalling a previously saved setting
(Select Procedure), to assign the footswitches to specific output sockets (Footswitch), and to control several
other functions (Menu), e.g. select language, touch tone control, output volume, or brightness.

On the rear panel the volume control, a ventilation hole, the equipotential bonding point, the AC power socket,
and two footswitch sockets can be found. Furthermore, for the connection of peripheral equipment 26-pin plugs
respectively 14-pin plugs can be connected to the LINK-IN or to the LINK-OUT socket.

On the bottom panel, a docking socket is featured. It can be used to connect the ESG-400 directly to the
USG-400 and upcoming devices. The ESG-400 is compatible with the new USG-400 ultrasonic generator to
enable the use of combined (US + HF) instruments.

NOTE

The electrosurgical generator is equipped with an
intelligent alarm system which determines alarm
conditions on the base of multiple variables. Depending

on the risk potential, alarms are classified in “high
priority”, “medium priority” and “low priority” alarms. An

alarm of higher priority overrides an existing alarm of
lower priority. If more than one alarm situation of equal
priority is determined, the one that occurred first is
displayed only. This electrosurgical generator complies
with the IEC 60601-1-8: 2006.

CAUTION

To avoid inadvertent coupling and / or shunting of high frequency currents
around the resistor elements, keep the resistors at least 10 centimeters away
from any metal surface including tabletops and other resistors. This is
especially true if several resistors are connected in series or parallel to obtain
a specified value. Do not allow the resistor bodies to touch each other.

NOTE

Keep test leads to the minimum length usable; lead inductance and stray
capacitance can adversely affect readings.

Carefully select suitable ground points to avoid ground loop error in
measurements.

For tests and checks requiring a power cord, use the power cord provided with
the electrosurgical unit.

Inspection is mandatory after repair, adjustment, update and upgrade.

2 Inspection procedures

The electrosurgical generator and the footswitch must undergo an inspection / safety check in yearly intervals
in accordance with the national statutory regulations. Inspection is also mandatory after repair, adjustment,
update and upgrade.

Generally the footswitches are inspected together with the electrosurgical unit. If a footswitch alone has to be
checked, only following tests are mandatory. The Numbers used referring to the Inspection Card in chapter 5-3:

For a single footswitch test number 2, 39 and 55 are mandatory.
For a double footswitch test number 2, 38, 39 and 55 are mandatory.

Follow these test instructions. All tests must be done with fully functional and calibrated test equipment and by
technicians trained in the service / maintenance of electrical medical devices. Record the test results in the
“Inspection Card” (refer to chapter 5-3, Inspection Card) for reference in future tests and provide the user of the
electrosurgical unit with a signed report.

During service / maintenance take care of the different hardware and software versions which may be
applicable. Information how to identify the hardware version can be found in chapter 3-2, Board Compatibility.
Information how to identify the software version can be found in chapter 1-3, Software version.

If the electrosurgical unit fails to meet any of the checks, the unit has to be adjusted according to chapter 6
(Adjustment) or refer to chapter 4 (Troubleshooting). If the failure still occurs, contact the manufacturer.

2-9 Checking the output power

NOTE

For the measurement of this (high current) value, it is important, that the cable
of the instrument is not “forming an inductor”. So do not wrap it up like a coil.
Either use it flat or unfold it completely.

1) All constraints for these tests are listed in the inspection card in chapter 5-3 under number 30 to 45. The
constraints are the output socket, the way of activation (e.g. footswitch, handswitch), the settings and the
load resistance. For measuring and to simulate the appropriate resistance the electrosurgical analyzer
(J002) is used.

2) Connect the appropriate output of the electrosurgical generator to the variable load of the electrosurgical
analyzer (J002) (according to the inspection card in chapter 5-3). Set the electrosurgical generator to
continuous measuring and set the internal measuring resistance to the appropriate value (according to the
inspection card in chapter 5-3). Start the measuring with the electrosurgical generator. (Settings of the
electrosurgical analyzer are done according to the analyzer’s instruction for use.)

3) Select the mode and set the power level according to the inspection card in chapter 5-3.

4) Activate the output power by pressing the corresponding footswitch pedal or handswitch button. During
the activated output the output tone can be heard.

5) Verify the output power is in the range according to the inspection card in chapter 5-3.

6) Repeat step 2 - 5 until test number 30 to 45 in the inspection card in chapter 5-3 have been checked.

ESG-400

7) Record the test results in the Inspection Card (see chapter 5-3).

2-10 Checking for certain features and error messages

1) All constraints for these tests are listed in the inspection card in chapter 5-3 under number 46 to 48. The
constraints are the output socket, the way of activation (e.g. footswitch, handswitch), the settings and the
load resistance. Low inductive high load resistors (J005) are used.

2) Connect the appropriate output of the electrosurgical generator to the appropriate load resistor (according
to the inspection card in chapter 5-3).

3) Select the mode and set the power level according to the inspection card in chapter 5-3.

4) Activate the output power by pressing the corresponding footswitch pedal. During the activated output the
output tone can be heard.

5) Verify the reaction of the electrosurgical generator according to the inspection card in chapter 5-3.

6) Repeat step 2 - 5 until test number 46 to 48 in the inspection card in chapter 5-3 have been checked.

7) Record the test results in the Inspection Card (see chapter 5-3).

7.022.211 / ISSUE 4 85 / 99 Chapter 5: Inspection

(J012) with each other. In this way a ring communication is established.

Fig. 5.2.14. Sample of an inspection label

2) The Error Message “E394 Communication error” should appear.

3) Record the test results in the Inspection Card (refer to chapter 5-3).

2-11-5 Restore of output power settings

Restore the settings by using the tables created in chapter 7-2-1. When not done while inspecting, restore all
power settings off the changed modes noted in table 7.2. Finally restore the last active procedure if applicable
and assign all modes to the sockets.

2-12 Inspection label (For applicable markets)

1) Cover or exchange an inspection label (as shown in Fig. 5.2.14) at the rear panel of the electrosurgical

unit’s housing and mark the due date of the next periodic safety check (month / year). The electrosurgical

unit must undergo a periodic safety check at annual intervals.

2) Record the due date in the safety check report (see chapter 5-3).
