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 844 UV/VIS Compact IC for the first time, check
that the mains voltage set on the instrument 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 21 of the
844 UV/VIS Compact IC.
2 Disconnect mains cable
Using a screwdriver, loosen fuse holder 22 below the mains
connection plug 21 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 22 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 1.6 A (slow-blow)
220…240 V 0.8 A (slow-blow)
4 Insert fuse
Change fuse if necessary and reinsert in fuse holder 22.
5 Install fuse holder
Depending on the desired mains voltage, insert fuse holder 22
in the 844 UV/VIS Compact IC so that the corresponding mains
