2.2 Mains connection

Follow the instructions below for connecting to the power supply. If

the instrument is operated with the mains voltage set wrongly and/or

wrong mains fuse there is a danger of fire!



2.2.1 Setting the mains voltage

Before switching on the 793 IC Sample Preparation Module for the first

time, check that the mains voltage set on the instrument (see Fig. 2)

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
