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

(see Fig. 3).
