Electrical Safety
WARNING
Connecting the MSD to power
sources which are not
equipped with protective earth
contacts creates a shock haz-
ard for the operator and can
damage the instrument.
Interrupting the protective
conductor inside or outside the
MSD or disconnecting the pro-
tective earth terminal creates a
shock hazard for the operator
and can damage the instru-
ment.
Make sure the power cords
supplied with the MSD are
appropriate for your country
and site before using them.
Maintain easy access to the
power cords so they can be
disconnected during mainte-
nance.
WARNING
The use of incorrect or make-
shift fuses or the short-circuit-
ing of fuse holders creates a
shock hazard for the operator
and can damage the instru-
ment. Replace fuses only with
fuses of identical current rat-
ing and type.
WARNING
Dangerous voltages are
present inside the MSD even if
the power switches are off.
Turn off the MSD power
switches and disconnect the
MSD power cords from their
outlets before removing any
covers unless you are specifi-
cally instructed to do other-
wise by this manual.
WARNING
Excessive fluctuations in the
line voltage can create a shock
hazard and can damage the
instrument. Make sure the sup-
ply voltage does not fluctuate
more than +5% or -10% from
the rated voltage. This equip-
ment must be installed in a
Category II environment as
defined in IEC664.
Thermal Safety
WARNING
Many parts of the MSD operate
at dangerously high tempera-
tures. Make sure the MSD is off
and these parts are cool before
removing any covers unless
you are specifically instructed
to do otherwise by this man-
ual.
Chemical Safety
WARNING
The foreline pump exhaust and
split vent exhaust will contain
traces of the chemicals you are
analyzing, as well as carrier
and reagent gases. 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 regula-
tions.
Hydrogen carrier gas is
extremely flammable. Explo-
sions can result if hydrogen is
allowed to build up in the MSD
or GC oven. Study the Hydro-
gen Carrier Gas Safety Guide
(HP Part No. 5955-5398) before
operating the MSD with hydro-
gen carrier gas.
CI reagent gases may be flam-
mable and/or toxic. Practice
appropriate safety precautions
when using and handling these
gases.
