Location
The 711 Liquino is a robust instrument and can therefore be used even un-
der rough conditions in laboratories and factories.
However, care must be taken that it is not exposed to a corrosive atmos-
phere. Regular care of the instrument is essential if it is used in rough sur-
roundings.
2.1.1 Mains connection
Follow the instructions given below to connect the instrument to the mains
supply. If the instrument is operated with the mains voltage incorrectly set
and/or the wrong mains fuse there may be a fire risk!
Setting the mains supply
Before switching on the 711 Liquino for the first time check that the mains
voltage set on the instrument (see illustration on following page) corre-
sponds to the local mains voltage. If this is
not the case then the correct
mains voltage must be set as follows:
• Pull out mains cable
Remove the mains cable from the mains connector of the 711 Liquino.
• Remove fuse holder
Use a screwdriver to loosen the fuse holder beside the mains connector
and remove completely.
• Check and replace fuses
Remove the built-in fuses for the required mains voltage from the fuse
holder and check their specifications:
100…120 V 0.315 A (slow-blow) Metrohm no. U.600.0011
220…240 V 0.16 A (slow-blow) Metrohm no. U.600.0008
• Insert fuses
Exchange fuses if necessary and replace them in the fuse holder.
• Set mains voltage
Remove the white fuse block from the fuse holder and reinsert it so that
the correct mains voltage is visible through the window in the fuse hold-
er.
