4. Preparations for using the AC power source
Before inserting the mains plug in the power outlet ensure that the
line voltage corresponds with the selected line voltage of the AC
power source.
* Ensure that the mains fuse in the fuse holder is of the required
rating (115 V AC / 230 V AC).
4.1. Selection of the required line voltage
The line voltage selector is placed on the rear of the instruments. Before
switching to another line voltage, turn power off and remove the mains
plugs from the outlet.
Remove the blank cover and switch the line voltage selector to the correct
position (115 V AC or 230 V AC). Then close the back cover.
Caution ! Never use the instrument without fully closed housing!
For mounting in to 19“ Racks or laboratory tables: Take care that the
distance of the inserted parts of the unit between the rack shut be
considered when removing the upper and down part of the housing. Take
care about safety protection class II.
4.2. Adjustment of output voltage
Caution ! Before connecting this power supply to the load ensure
that the specified maximum output current is not exceeded. Further
please consider that only one load is allowed to connect to the AC-
power source.
1. Disconnect the power cord from the AC power source.
2. Adjust the desired output voltage with the voltage control.
3. The power supply is now ready for operation.
