1.4 Safety notes
1.4.1 Electrical safety
While electrical safety in the handling of the 791 VA Detector is assured
in the context of the specifications IEC 1010-1 (protection class 1, de-
gree of protection IP40), the following points should be noted:
• Mains connection
Setting of the mains voltage, checking the mains fuse and the
mains connection must be effected in accordance with the instruc-
tions in section 2.2.
• Opening the 791 VA Detector
If the 791 VA Detector is connected to the power supply, the instru-
ment must not be opened nor must parts be removed from it, other-
wise there is a danger of coming into contact with components which
are live. Hence, always disconnect the instrument from all voltage
sources before you open it and ensure that the mains cable is
disconnected from mains connection 26 !
• 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 791 VA Detector, you should earth yourself and any tools
you are using by touching an earthed object (e.g. housing of the
instrument or a radiator) to eliminate any static charges which exist.
1.4.2 General precautionary rules
• Handling of solvents
Check all lines periodically for possible leaks. Follow the relevant
instructions regarding the handling of flammable and/or toxic solvents
and their disposal.
