f) REMOTE control (only SPS 1560 PFC)
Through the built-in “REMOTE” control connection, the voltage setting can take place with an external voltage source
or through an externally adjustable resistance (short “poti”) and it´s possible to switch the DC output on/off.
The REMOTE connection takes place on the rear REMOTE built-in plug
(14)
.

Preparation of the remote control connection.
1.
Turn the central screw of the supplied slide-in jack and remove the front, black contact jack by means of a small
turning movement.
2.
Draw the five connecting cables with a conductor cross-section of at least 22AWG (=0,34 mm
2
) through the metal
sleeve from the rear. Solder these five cables firmly and carefully to the soldering lugs no.1,2,3,7 and 8 of the
black contact jacks.
3.
Mark the loose ends of the cables with the corresponding contact numbers (1-3) to rule out any confusion.
4.
Insert the black contact jack in the reverse order into the metal sleeve and screw these firmly.

Control through external voltage source
The power unit can be remote-controlled by means of an external voltage source of 0 to 5V/DC over the complete
output voltage range.
Proceed as follows for connection:
1. 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.
