• This electrosurgical unit should be tested by
a Hospital Qualified Biomedical Technician
on a periodic basis to ensure proper and safe
operation. It is recommended that examina-
tion of the ESU be performed at least yearly.
• Refer all servicing to a Hospital Qualified
Biomedical Technician. Your CONMED sales
representative will be happy to assist you in
getting your equipment serviced.
• High voltages are developed within the ESU
that are accessible when the top cover is
removed. These voltages are potentially dan-
gerous and should be treated with extreme
caution.
• The high voltage DC power supply in the
System 5000™ is equipped with a bleeder
resistor to dissipate the charge on the filter
capacitor. However, it takes several seconds
after power is removed to bleed that charge
down to a safe level. It is recommended that
at least thirty (30) seconds be allowed to
elapse before touching or attempting to per-
form any maintenance involving the power
supply or power amplifier.
• Never remove or install any parts with the
power cord connected to AC mains.
• Avoid contact with the output leads when the
ESU is activated. Periodically inspect the
test leads used for the output connections for
obvious defects.

Group 2
The System 5000 Electrosurgical Unit must emit electromagnetic
energy in order to perform its intended function. Nearby elec-
tronic equipment may be affected.
Class A
The System 5000 Electrosurgical Unit is suitable for use in all
establishments, other than domestic establishments and those
directly connected to the public low-voltage power supply net-
Class A
work that supplies buildings used for domestic purposes.

• Although this ESU will withstand momentary
short circuits on the output, prolonged short
circuits may damage the ESU. Short-circuit-
ing the output should be avoided since it is
neither necessary nor desirable.
• Since the clinical use of electrosurgical units
is intermittent in nature with duty cycles on
the order of 10%, this ESU is not designed
to operate for extended periods of continu-
ous output. When testing, it is recommended
that duty cycles be limited to 10 seconds
activation with delays of 30 seconds between
activations.
• Activating the System 5000™ in other than its
normal operating position impairs the heat
dissipation capability of the heat sink.
• Ensure that the two top cover screws are tight-
ened and always perform a power-up check to
confirm a normal power-up sequence before
returning the ESU to service.
• Improperly connecting test equipment can
cause electric shock and destruction of equip-
ment.
• Turn unit off and wait until storage capacitors
have discharged before connecting test equip-
ment.
• Loss of power supply isolation can cause elec-
trical shock. When servicing the high voltage
power supply, assume internal isolation is
compromised until verified otherwise.
