Proceed as follows for connection:
• Always connect the supply cables from the power unit to the consumer. Pay atten-
tion to correct polarity.
• Press the orange-coloured terminal on the SENSE connection inwards with a small
screwdriver and insert the cables into the green terminal openings. Check that
they are plugged firmly.
• Now connect the two "SENSE" cables to the consumer observing the correct
polarity. The conductor cross-section for the "SENSE” cables must be at least
22AWG (= 0,34mm2) .
• Always slacken the connection in the reverse order (first of all the "SENSE” cables
and then the connecting cables).
Make sure that you contact the SENSE cables as close as possible to
the connecting point of the consumer.
Never short the "SENSE" cables.
REMOTE control (only SPS 1560 PFC)
Through the built-in "REMOTE” control connection, the voltage setting can take pla-
ce with an external voltage source or through an externally adjustable resistance
(short "poti”).
The REMOTE connection takes place on the rear REMOTE built-in plug (14).
Preparation of the remote control connection.
Turn the central screw of the supplied slide-in jack and remove the front, black
contact jack by means of a small turning movement.
Draw the three connecting cables with a conductor cross-section of at least 22AWG
(=0,34mm2) through the metal sleeve from the rear. Solder these three cables firmly
and carefully to the soldering lugs no.1, no.2 and no.3 of the black contact jacks.

Mark the loose ends of the cables with the corresponding contact numbers (1-3) to
rule out any confusion.
Insert the black contact jack in the reverse order into the metal sleeve and screw the-
se firmly.
Control through external voltage source
The power unit can be remote-controlled by means of an external voltage source of
0 to 5VDC over the complete output voltage range.
Proceed as follows for connection:
Connect the connecting cable of the REMOTE plug as illustrated.
Connection 2 to the plus pole (+) of the voltage supply and
connection 3 to the minus pole (+) of the voltage supply.
Connection 1 is not required.
Caution!
The voltage on the remote control connection may not exceed 5V.
The connections may not be shorted.
Switch off the switched-mode power supply and then connect the REMOTE plug tot
the rear remote connection. Screw down the external fastening ring.
Turn the voltage of the external voltage source to zero.
Slide the rear VOLTAGE REMOTE
switch to the "ON" position.
Switch the switched-mode power supply on. The desired output voltage can now be
set through the external voltage source. Control the complete adjustment area for
correct function.
If this remote control function is no longer required, the switch to the "OFF” position.
