Hints and tips
- The mains plug must be connected into a free acces-
sible mains socket.
- The polarity of the output can be internally reversed by
means of the PCB "UMPOLER".
This may only be carried out by trained personnel.
- On units above 300V the 0V-HV output is internally
connected with the safety ground connector PE.
In case the output has been reversed, than the +
output is connected to the safety ground
connector PE.
- The overvoltage protection (OVP) can be adjusted on
the front panel by means of a screw driver. The value
can be indicated on the voltmeter after pressing the
"Preset" button. In case the OVP is activated, the unit
can be reset to normal operation by activating the "Re -
set" button.
- The included plug must always be plugged in to the
analogue interface socket. See page 14.
