connection
Please observe the following rules when connecting the instrument to
the electricity supply. If the instrument is operated with an incorrectly
set mains voltage and/or an incorrect mains fuse then it represents a
fire hazard!
2.2.1
Setting the mains voltage
Before you switch on the 833 Liquid Handling Unit for the first time
please check that the mains voltage set on the instrument (see Fig. 3)
corresponds to your local mains voltage. If this is not the case then you
must alter the mains voltage as follows:
1 Pull out mains cable
Remove the mains cable from mains supply connection 9 of the
833 IC Liquid Handling.
2 Remove the fuse holder
Use a screwdriver to loosen fuse holder 11 beneath the mains
supply connection and remove it completely.
3 Check the fuse
Carefully remove the built-in fuse for the intended voltage from
the fuse holder and check its specifications (the position of the
fuse in the fuse holder is indicated by the white arrow beside the
voltage range):
100
…
120 V 0.5 A (slow blow) Metrohm No. U.600.0013
220
…
240 V 0.25 A (slow blow) Metrohm No. U.600.0010
4 Insert fuse
Exchange the fuse if necessary and replace it in the fuse holder.
5 Insert fuse holder
Depending on the required mains voltage, insert the fuse holder
in the 833 IC Liquid Handling Unit 833 so that the appropriate
voltage range can be read normally and the adjacent white
arrow points to the white bar printed beneath the fuse holder
