Start-up

General information

The switching power supply is not a charger. To charge batteries, use suitable char-
gers with charging cut-off.

Connecting the power cable

• Connect the power cable with earthing contact provided to the power supply jack
(5) on the power supply. Make sure it is plugged in securely.
• Connect the power cable to a mains socket with earthing contact.

Setting the desired output voltage

• Make sure that there are no consumers connected to the mains power supply.
• Switch on the power supply at the power switch (1). The power indicator (2) should
light up.
• Check the output voltage with a voltmeter. If the preset voltage is not the desired
voltage, it can be reset in the range of 12.6 V to 14.8 V.
• Gently remove the plastic cover (4) with a flat-tip screwdriver.
• With a suitable screwdriver, set the desired output voltage and check the voltage
with a voltmeter.
• Carefully replace the cover.

Connecting a consumer

• Make sure the consumer is switched off.
• Check that the output voltage is correct.
• Connect the positive pole (+) of the consumer to the red terminal "+" (8) and
• the negative pole (-) of the consumer to the black terminal "-" (7).
• 4 mm standard connectors could be used for this purpose but we strongly recom-
mend using terminal screws for currents over 20 A (the jack heads can be screwed
on).
Make sure that the consumers are switched off when being connected
to the switching power supply. Sparks may be generated when a con-
sumer which is switched on is connected to the jacks. This may dama-
ge the screw terminals as well as the connected cables.
• Always connect the "SENSE" measuring cables, as well. See next chapter
