Connecting the power supply unit
Proceed as follows:
1
Connect the plug of the external power supply unit with the power
socket
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 first need to pull back
the outer plug sleeve.
2
Connect the power supply cable with the external power supply unit
of the coulometer and with the power supply.
CAUTION
Switch off the 899 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.
4.3.2
Connecting the Power Box
As an alternative to the power from the power supply, it is possible to
provide the 899 Coulometer with electricity through the 6.2164.500
Power Box. This means that you can also use the instrument in environ-
ments in which no stable power supply is available. Details regarding the
Power Box can be found in the respective manual.
