3.3 Installation of 747 VA Stand
If the 746 VA Trace Analyzer is connected to the power supply, neither
the 746 VA Trace Analyzer nor the 747 VA Stand may be opened or
parts removed as there is a danger of contact with live components.
Before the 746 VA Trace Analyzer or 747 VA Stand is opened to
change components or for maintenance or repair work, the mains
cable must thus always be disconnected from the mains connection
plug 13 13 of the 746 VA Trace Analyzer!
