Figure 7 Connecting the power supply unit
Proceed as follows:
1 Connect the plug of the external power supply unit with the mains
connection (2-7) of the Coulometer.
Note
The plug of the power supply unit is protected against accidental
disconnection of the cable by means of a pull-out protection fea-
ture. If you wish to pull out the plug, you will first need to pull
back the outer plug sleeve.
2 Connect the mains cable with the external power supply unit of the
Coulometer and with the mains supply.
Caution
Switch off the Coulometer correctly by pressing the red [STOP] key
before you interrupt the electricity supply. If this is not done, then there
is a danger of data loss.
3.3.2 Connecting the Power Box
As an alternative to the power supply from the mains supply, the option
exists of providing the 899 Coulometer with electricity through the
6.2164.500 Power Box. This means that you can also use the instrument
in environments in which no stable mains supply is available. Details
regarding the Power Box can be found in the respective manual.
