Connecting a device

When connecting a consumer, make sure that it is connected to the power sup-
ply when switched off. The maximum current consumption of the device to be
connected must not exceed the capacity indicated in the technical specifica-
tions.
For series connection of several power supplies, contact dangerous voltages (>
70 VDC) are created where contact can be fatal. As of this voltage, you may only
use insulated accessories.
Avoid the use of non-insulated metallic cables and contacts. All these spots
must be covered with suitable, flame-resistant insulation materials or by means
of other measures, which serve to prevent direct contact and short circuits.
Ensure a sufficient cable diameter for the intended current.
Normal operation „master“
In normal master operation, the device is controlled using the two adjusters for voltage and current. Con-
trol through other devices is not possible.
• Switch on the mains power supply at the power switch (1). The voltage and power display
(7 and 8) appear after approx. 1 to 2 seconds and show „0000“.
• • Set the parameters according to your specifications as described in the chapter „Commissioning“.
• Check once again that the output voltage is set correctly by pressing the button „REVIEW“ (3).
• Connect the positive terminal (+) of the load with the red socket „+“ (16) and the negative terminal
with the black socket „-“ (17).
• Alternatively, you can also realise the connection via the plug-type
clamps on the back. To do so, press the little slot inwards with a screw-
driver and insert the insulated conductor into the round opening. The
positive pole corresponds to the clamp „O/P+“ (19), the negative pole
to the clamp „O/P-“ (20). Unlatching is done the same way.
• Activate the DC output by pressing the button „OUTPUT ON“ (5). The
status LED is lit (5) and the display (8) shows the output voltage.
• Now you can switch on the connected consumer.
• The current consumption of the connected consumer is displayed on
the power display „A“ (7).
