3.1 Electrical safety
While electrical safety in the handling of the 797 VA Computrace Stand is assured in
the context of the specifications IEC 61010-1 (protection class 1), the following points
should be noted:
• Mains connection
Setting mains connection must be effected in accordance with the
instructions in section 2.2.1.
• Opening the instrument
When the 797 VA Computrace Stand is connected to the power supp-
ly, the instrument may not be opened nor parts of them be removed,
otherwise there is a danger of coming into contact with components
which are live. Before you open the 797 VA Computrace Stand to
change components or for maintenance or repair work, always switch
on the instrument by setting the mains switch to the ON position and
then disconnect the mains cable from the mains connection plug 16
of the 797 VA Computrace Stand!
• Protection against static charges
Electronic components are sensitive to static charging and can be de-
stroyed by discharges. Before you touch any of the components inside
the 797 VA Computrace Stand, you should earth yourself and any
tools you are using by touching an earthed object (e.g. metal housing
of the instrument or a radiator) to eliminate any static charges that
exist.
