6 Preparations
The mains cables supplied with the instrument are three-core and equipped with a plug
with an earthing pin. If a different plug has to be fitted, the yellow/green lead must be
connected to the protective earth. Each break in the earthing inside or outside the instru-
ment can make it a hazard.
When the instrument is opened or if parts of it are removed, certain components may be
live if the instrument is connected to the mains. The mains cable must therefore always be
unplugged when certain adjustments are made or parts replaced.
The cable should only be plugged in and unplugged when the instruments are switched
off.
