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).
