Connection and putting into service
A How to connect and put into service power supply units
Connect the mains plug to the mains socket. The switched-mode power supply unit
will now be in operation, which can be seen on the red LED which operates, and runs
"in the economy mode" = lowest power input.
Attention:
Never turn the setting knob during operation. This can damage
any load that is connected (a radio or walkman or the like), on one
hand, and destroy the power supply unit by contact-breaking
sparks on the switching contacts, on the other. Do not use unsuit-
able tools to make settings. Only use the adjusting tool which is
included. When making settings always be sure the arrow points
accurately to the respective voltage marking.
B How to connect loads
When connecting a load make sure it is switched off before joining it to the power
supply unit.
The output voltage is adjustable from 6 V D.C. (D.C. = "direct current voltage") to 15
V D.C., which covers most applications. Note that the power input of the load con-
nected may not exceed a maximum of 4,200 mA (= 4.2 A) in the range from 6 V D.C.
to 12 V D.C. The maximum input is 3,200 mA (= 3.2 A) in the range exceeding 13.5 V
D.C. to 15 V D.C.
There is an arrow marking on the connection jack at the end of the cable. These
arrow markings are on either side of the low-voltage plugs which are included. A cer-
tain connection polarity belongs to each arrow marking. The result is as follows,
depending on the connection to the jack:
inside "+" + -•)- - outside "-" or
inside "-" - -•)- + outside "+"
Note:
The front end is considered to be "inside" for jack connectors.
