The 762 Interface has a power supply which automatically adjusts itself
to the existing mains voltage (100...240 V) and frequency (50...60 Hz).
It is equipped with an electronic overload protection device and also
has two fuses; however, these should only be exchanged by Metrohm
service technicians.
The instrument is supplied with one of three mains cables
• 6.2122.020 with plug SEV 12 (Switzerland, ...)
• 6.2122.040 with plug CEE(7), VII (Germany, ...)
• 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 the earthing socket 7 7 (protection class 1).
Any break in the earthing inside or outside the instrument can make it
a hazard!
Plug the mains cable into mains connection plug 8 8 at the 762 IC Inter-
face (see Fig. 3 and Fig. 5).
The 762 IC Interface is switched on and off using mains switch 1 1 (see
Fig. 2 and Fig. 4). When the instrument is switched on the mains pilot
lamp 2 2 lights up.
