2.2 Mains connection
2.2.1 Mains voltage and fuses
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.
2.2.2 Mains cable
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 77 (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 88 at the 762 IC Inter-
face (see Fig. 3 and Fig. 5).
2.2.3 Switching the instrument on/off
The 762 IC Interface is switched on and off using mains switch 11 (see
Fig. 2 and Fig. 4). When the instrument is switched on the mains pilot
lamp 22 lights up.
