device or the mains cable visible damages indicates, - the device any longer does not operate, - after longer
storage under unfavorable conditions, - after heavy transport stresses.

4. Line-up
a) link connecting it the GND contact - power supply plugs of the power supply unit with a connector 230V/50Hz
/60Hz. paying attention it when connecting a consumer absolutely to the fact that this is attached in the not
switched on status. A switched on consumer can lead with the link to the output terminals of the power supply
unit to a sparking at the connecting terminals, which can damage again the female connectors or the attached
lines and/or their clamps. Switch the power supply unit on over the power switch.
Note! With longer operation with max. current consumption (ä) or in the case of short-circuit the radiator box in the
power supply unit becomes very warm. Caution! Burn danger! Absolutely pay attention therefore to a sufficient
ventilation of the power supply unit and never cover them the ventilation slots on the device waiters - or device
lower surface, in order to avoid possible damage.
b) Voltage adjustment
Turn first the rough reset knob for the current limiting a little to the right (in the clockwise direction), until the LED (=
light emitting diode) for current limiting goes out. In the same instant the LED for the voltage adjustment begins to
light up. Now you can adjust the desired output voltage.
c) Adjustment of the current
limiting shooting it the output terminals with switched off power supply unit briefly. Switch the network on -. The
display for output current displays, depending upon adjustment of the rough or fine reset knob for current limiting, a
value. Stop the current limiting, i.e. the " maximum stream ", with which the power supply unit is to limit. After
adjustment they open the short-circuit with switched off power supply unit, since otherwise an outline spark can
develop.
Note! Absolutely consider the safety notes with paragraph 2 of this guidance.
