SAFETY - 10
WARNING
Beware of
electric shock
• Voltages up to 100 V AC and 30 kV DC are used inside this
instrument. Do not touch inside or you may receive an electric shock.
• Do not remove the covers of column unit, control unit or power unit
and do not touch internal parts or circuits while the instrument power
is turned on. There is a hazard of fatal or serious injury due to
electric shock.
• Avoid removing the covers of the instrument. If they must be
removed, make sure to first turn off all power to the instrument.
Electron Gun / Ion pump Baking
• The electron gun and ion pump are heated to about 250°C in order to
keep the electron gun in a high vacuum. Touching these sections
would result in burns.
Beware of high
temperature
Rotary Pump
• The temperature of the oil rotary pump rises up to about 70°C, while it
is operating. Touching the pump may also result in burns.
Beware of low
temperature
Liquid Nitrogen
• When you replenish liquid nitrogen in the cold-trap of DP and the
anti-contamination trap, be sure to wear eye-protection glasses and
protective gloves to keep liquid nitrogen from splashing on the eyes or
the skin.
• Anyone working on the electrical part of the system should follow the
correct lock-out tag-out procedures for that location.
• The user should prepare a mains switch box on which the lock-out
and the tag-out procedures are provided.
• Electrical hazards can occur if lock-out tag-out procedures are not
followed.
Magnetic Fields
• The ion-pump produces magnetic fields. There are fringing magnetic
fields of about 100 Gauss from the ion-pump and 10 Gauss at the
outside of the ion-pump cover.
Any person who has a pacemaker embedded is not allowed to
approach the ion-pump.
Do not bring near to the ion-pump wristwatches and magnetic cards
that are susceptible to magnetic fields.
