7.1 Electrical safety
While electrical safety in the handling of the 746 VA Trace Analyzer and 747 VA
Stand is assured in the context of the specifications IEC 1010-1 (protection class I,
degree of protection IP20), the following points should be noted:
• Mains connection
Setting the mains voltage, checking the mains fuse and the mains
connection must be effected in accordance with the instructions in
section 3.2.
• Opening the instruments
When the 746 VA Trace Analyzer and 747 VA Stand are connected to
the power supply, neither the 746 VA Trace Analyzer not the 747 VA
Stand or the 695 Autosampler may be opened nor parts of them be
removed, otherwise there is a danger of coming into contact with
components which are live. Always disconnect the instruments from
all voltage sources before you open it and ensure that the mains
cable is disconnected from mains connection plug 13 13 !
• Protection against static charges
Electronic components are sensitive to static charging and can be
destroyed by discharges. Before you touch any of the components
inside the 746 VA Trace Analyzer or 747 VA Stand, you should earth
yourself and any tools you are using by touching an earthed object
(e.g. green housing of the instrument or a radiator) to eliminate any
static charges which exist.
