5.1. Setting up and connecting the instruments

785 DMP Titrino

150

5 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 instrument
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.

5.1  Setting up and connecting the instruments

5.1.1  Titrino with Stirrer or Titration Stand

The 722 Rod Stirrer, the 727, or the 703 Ti Stand with 6.2108.100
cable can also be connected instead of the 728 Magnetic Stirrer.
