The instrument is supplied with one of three mains cables:
• 6.2122.020 with plug SEV 12 (Switzerland, … )

• 6.2133.070 with plug NEMA 5-15 (USA, … )
which are three-cored and fitted with a plug with an earthing pin. If a different plug
has to be fitted, the yellow/green lead (IEC standard) must be connected to protec-
tive earth (protection class I). If there is no socket with earthing available, you must
connect the earth socket 88 of the instrument to a perfect earthing conductor.
Any break in the earthing inside or outside the instrument can make it
a hazard!
