2.2 Safety Considerations

Safety note:
Never operate the 760 Sample Changer without splash protection
and plug cover being mounted. The plug cover prevents any con-
tamination of the connectors, caused by spilled solvents or chemi-
cals.


If failure or malfunctioning occurs during operation of the 760 Sam-
ple Changer, the Metrohm Service Department should be
consulted.

If opening the instrument is unavoidable, the following safety pre-
cautions are to be strictly adhered to:

Before opening the instrument disconnect it from all electri-
cal sources. Make sure that the power plug has been pulled
out.



Electronic components are sensitive to static electricity and can be
destroyed by discharge. Before touching any components inside
the instrument, both the person and his tools should be grounded
by grasping a grounded object (for example: a metallic part of the
casing of the instrument or a radiator) in order to eliminate any
static electricity.

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 ac-
quainted with the associated dangers.

When peripheral instruments are connected to the 760 Sample
Changer, 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 oper-
ated safely, it must be put out of operation.
