2.4 Mains connection
Follow the instructions below for connecting to the power supply. If the
instrument is operated with a mains voltage set wrongly and/or wrong
mains fuse, there is a danger of fire!
2.4.1 Setting the mains voltage
Before switching on the 861 Advanced Compact IC for the first time
check that the mains voltage set on the instrument (see Figure 11)
matches the local mains voltage. If this is not the case, you must reset
the mains voltage on the instrument as follows:
1 Disconnect mains cable
Disconnect mains cable from mains connection plug 17 of the
861 Advanced Compact IC.
2 Remove fuse holder
Using a screwdriver, loosen fuse holder 18 below the mains
connection plug 17 and take out completely.
3 Check and change fuse if necessary
Carefully take the fuse installed for the desired mains voltage out
of fuse holder 18 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 1.0 A (slow-blow) Metrohm No. U.600.0016
220 … 240 V 0.5 A (slow-blow) Metrohm No. U.600.0013
4 Insert fuse
Change fuse if necessary and reinsert in fuse holder 18.
5 Install fuse holder
Depending on the desired mains voltage, insert fuse holder 18
in the 861 Advanced Compact IC so that the corresponding
mains voltage range can be read normally and the adjacent
white arrow points to the white bar imprinted below the fuse
holder (see Figure 11).
