774 Oven Sample Processor, Instructions for use 11
If opening the instrument is unavoidable, the following safety precautions
are to be strictly adhered to:
Before opening the instrument disconnect it from all electrical
sources. Make sure that the power plug has been pulled out.
Only in exceptional cases should the instrument be opened while it is
switched on. Because parts that conduct current are exposed in this case,
this should only be undertaken by an expert who is acquainted with the as-
sociated dangers.
Electronic components are sensitive to static electricity and can be de-
stroyed by discharge. Before touching any components inside the instru-
ment, both the person and his tools should be grounded by grasping a
grounded object (for example: a metallic part of the casing of the instru-
ment or a radiator) in order to eliminate any static electricity.
When peripheral instruments are connected to the 774 Oven Sample Proc-
essor, the sample changer and the instruments to be connected have to be
switched off, otherwise all instruments could suffer damage.
If it becomes apparent that the instrument can no longer be operated safely
it must not be used at all.
