2.6 Mains 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!
2.6.1 Setting the mains voltage
Before switching on the 818 IC Pump for the first time, check whether
the mains voltage set on the instrument (can be read in the mains
voltage selector 11) matches the local mains voltage. If this is not the
case, you must switch the mains voltage by pushing the mains voltage
selector 11 with a screwdriver:
1 Disconnect mains cable
Disconnect mains cable from mains connection plug 10 of the
818 IC Pump.
2 Remove fuse cover
Using a screwdriver, lever out fuse cover 10 forwards until it
opens.
3 Check and change fuses if necessary
Carefully take the fuses installed for the desired mains voltage
out of the fuse holder and check its specifications:
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
Change fuse if necessary and reinsert in fuse holder.
4 Install fuse holder
Reinsert fuse holders in the instrument (the arrows printed on the
holders must point in the same direction as the arrows on the
inside of fuse cover 10).
5 Install fuse cover
Push in fuse cover 10 firmly until it clicks into place.
6 Connect mains cable
Plug mains cable into mains connection plug 10.
