Electrical Safety
WARNING
Connecting the system to
power sources that are not
equipped with protective earth
contacts creates a shock
hazard for the operator and can
damage the instruments.
Interrupting the protective
conductor inside or outside the
system or disconnecting the
protective earth terminal
creates a shock hazard for the
operator and can damage the
instruments.
Make sure the power cords
supplied with the system are
appropriate for your country
and site before using them.
Maintain easy access to the
power cords so they can be
disconnected during
maintenance.
WARNING
The use of incorrect or
makeshift fuses or the short-
circuiting of fuse holders
creates a shock hazard for the
operator and can damage the
instrument. Replace fuses only
with fuses of identical current
rating and type.
WARNING
Dangerous voltages are present
inside the system even if the
power switches are off. Turn
off the system power switches
and disconnect the system
power cords from their outlets
before removing any covers
unless you are specifically
instructed to do otherwise by
this manual.
WARNING
Excessive fluctuations in the
line voltage can create a shock
hazard and can damage the
instrument. Make sure the
supply voltage does not
fluctuate more than +5% or -
10% from the rated voltage.
This equipment must be
installed in a Category II
environment as defined in
IEC664.
Thermal Safety
WARNING
Many parts of the system
operate at dangerously high
temperatures. Make sure the
system is off and these parts
are cool before removing any
covers unless you are
specifically instructed to do
otherwise by this manual.
Chemical Safety
WARNING
The foreline pump exhaust and
split vent exhaust will contain
traces of the chemicals you are
analyzing. These could
potentially be toxic. Vent the
foreline pump exhaust and split
vent exhaust outside your
laboratory or into a fume hood.
Be sure to comply with all local
environmental regulations.
Hydrogen carrier gas is
extremely flammable.
Explosions can result if
hydrogen is allowed to build up
in the MSD or GC oven. Study
the Hydrogen Carrier Gas
Safety Guide
(Part No. 5955-5398) before
operating the MSD with
hydrogen carrier gas.
