Fire/Explosion Hazards
Generator Electric Shock Hazards
Warning
Explosion Hazard Do not install the generator in the presence of flammable
anesthetics, gases, liquids, or objects.
Fire Hazard Do not place active accessories near or in contact with flammable
materials (such as gauze or surgical drapes). Electrosurgical accessories that are
activated or hot from use can cause a fire. Use a holster to hold electrosurgical
accessories safely away from personnel and flammable materials.
Fire Hazard Do not use extension cords.
Fire Hazard For continued protection against fire hazard, replace fuses only
with fuses of the same type and rating as the original fuse.
Warning
Do not remove any covers or panels exposing the internal components. Refer to
a Valleylab representative for service.
Connect the generator power cord to a properly grounded receptacle. Do not use
power plug adapters.
Do not connect a wet power cord to the generator or to the wall receptacle.
Always turn off and unplug the generator before cleaning.
Do not touch any exposed wiring or conductive surfaces while the generator is
disassembled and energized. Never wear a grounding strap when working on an
energized generator.
When taking troubleshooting measurements use appropriate precautions, such
as using isolated tools and equipment, using the “one hand rule,” etc.
Potentially lethal AC and DC voltages are present in the AC line circuitry, high
voltage DC circuitry, and associated mounting and heat sink hardware described
in this manual. These potentials are not isolated from the AC line. Take
appropriate precautions when testing and troubleshooting this area of the
generator.
High frequency, high voltage signals that can cause severe burns are present in
the RF output stage and in the associated mounting and heat sink hardware.
Take appropriate precautions when testing and troubleshooting this area of the
generator.
