2.2 Mains connection
Follow the instructions below for connecting to the power supply. If
the instrument is operated with the mains voltage set wrongly and/or
wrong mains fuse there is a danger of fire!
2.2.1 Setting the mains voltage
Before switching on the 766 IC Sample Processor for the first time,
check that the mains voltage set on the instrument (see Fig. 2) matches
the local mains voltage. If not, reset the mains voltage on the instru-
ment as follows:
1 Disconnect mains cable
Disconnect mains cable from mains connection plug 25 25 of the
766 IC Sample Processor.
2 Remove fuse holder
Using a screwdriver, loosen fuse holder 24 24 beside the mains
connection 25 25 and take out completely.
3 Check fuse
Carefully take the fuse installed for the desired mains voltage out
of fuse holder 24 24 and check its specifications (the position of the
fuse in the fuse holder is marked by the white arrow imprinted
next to the mains voltage range):
100 … …120 V 0.5 A (slow-blow) Metrohm-Nr. U.600.0013
220 … …240 V 0.25 A (slow-blow) Metrohm-Nr. U.600.0010
4 Insert fuse
Change fuse if necessary and reinsert in fuse holder 24 24.
5 Install fuse holder
Depending on the desired mains voltage, insert fuse holder 24 24 in
the 766 IC Sample Processor so that the corresponding mains
voltage range can be read normally and the adjacent white
arrow points to the white bar imprinted on the right side of the
fuse holder (see Fig. 3).
