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.
