1.4.1 Electrical

safety

While electrical safety in the handling of the 792 Basic IC is assured in

the context of the specifications IEC 1010-1 (protection class 1, degree

of protection IP20), the following points should be noted:

x 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 2.4.

x Opening the 792 Basic IC

If the 792 Basic IC is connected to the power supply, the instrument

must not be opened nor must parts be removed from it, otherwise

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 discon-

nected from mains connection 12

x 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 792 Basic IC, you should earth yourself and any tools you

are using by touching an earthed object (e.g. housing of the instru-

ment or a radiator) to eliminate any static charges which exist..
