110 Safety
Specific symbols, drawing attention to safety hazards have been applied on
appropriate places on the instrument. The following symbols can be encountered:
Instruction manual symbol. Indicates that the user should refer to the manual
before operating the equipment.
Indicates dangerous voltage. (terminals fed from the interior by voltage
exceeding 1000 V must be so marked.)
Protective conductor terminal. For protection against electrical shock in case of
a fault. Used with field wiring terminals to indicate the terminal, which must be
connected to ground before operating equipment.
Radioactive hazard. Indicates that the instrument contains radioactive
components, which may cause personal injury when handled incorrectly.
Skin puncture. Indicates sharp or suddenly moving parts such as injection
needles that may cause injury.
Hot surface.
Indicates parts that may cause burns when touched.
Cryogenic frostbite. Contains extremely cold material (such as liquid nitrogen,
carbon dioxide) that may cause injury when handled carelessly.
Static discharge warning. Item contains parts or information that can be
damaged by electrostatic discharge. Take care for proper grounding before
handling.
Do not touch. Touching this item may result in damage to the instrument or
personal injury.

110 Safety
WARNINGS
The following general safety warnings must be observed during all phases of
operation, service, and repair of the 436-GC/456-GC. Failure to comply with these
precautions or with specific warnings elsewhere in this manual violates safety
standards of design, manufacture, and the intended use of the instrument.
Bruker, Inc. assumes no liability for failure to comply with these requirements
HEATED COMPONENTS
Turn off the oven and injector/detector heated zones and allow them sufficient
time to cool before servicing those areas. If you must perform service on
components that have not fully cooled, wear protection gloves.
VOLTAGE CARRYING COMPONENTS
Whenever possible, disconnect the 436-GC/456-GC from its power source before
working on or near voltage carrying components of the 436-GC/456-GC.
When the power to the GC is turned on, potentially dangerous voltages exist on
these additional components:
All electronics boards.
All internal wires and cables connected to theseboards.
To protect against electrostatic discharge, use a static control wrist
strap connected to a ground. If you do not use static protection, you
may damage the electronics of a board.
BEFORE YOU START
Allow the injectors and oven to cool before removing the
covers. The metal surfaces of the GC are very hot and
could burn your skin. Turn off the power to the GC and
disconnect the power cord at their source.
Be sure to wear an ESD strap grounded to the GC
chassis while performing all procedures.
