5. Operation
5.1 General instructions
Connect the experiment set-up with the
power supply unit.
Only switch the power supply on when the
set-up has been completed.
Modifications to the experiment set-up may
only be performed when the system is OFF
and de-energized.
Set to the desired voltage at the voltage
selector switch.
5.2 Tapping voltage
To tap an AC voltage, connect the black 4
mm
connection
experiment set-up.
To tap a DC voltage, connect the blue
negative and red positive pole (6) to the
experiment set-up.
5.3 Replacing fuses
Switch off the power supply and make sure
that the mains plug has been pulled out.
Open the fuse holder on the side of the unit
using a flat-head screwdriver and unscrew it.
Replace the fuse and screw the holder back
on.
6. Storage, cleaning, disposal
Store the apparatus in a clean, dry and dust-
free location.
Disconnect from the mains power prior to
cleaning the unit.
Do not use aggressive agents or solvents to
clean the equipment.
Use a soft, damp cloth to clean.
Dispose of the package at a local recycling
depot.
If the device itself needs to
be disposed of, it does not
belong
in
the
household waste. When
used in private households,
it can be disposed of with
the local public recycling
facilities.
Please comply with all valid regulations
regarding the disposal of electrical scrap.
