The voltage on the remote control connection may not exceed 5V.
The connections may not be shorted.
2. Switch off the switched-mode power supply and then connect the REMOTE plug to the rear remote connection.
Screw down the external fastening ring.
Turn the voltage of the external voltage source to zero.
3.
Slide the rear VOLTAGE REMOTE switch to
the “ON” position.
4. Switch the switched-mode power supply on. The desired output voltage can now be set through the external volt-
age source. Control the complete adjustment area for correct function.
5. If this remote control function is no longer required, the switch to the “OFF” position.

Control through a controllable resistance (poti)
The power unit can be remote-controlled by means of an external poti of 5 KOhm over the complete output voltage range.
Proceed as follows for connection:
1. Connect the connecting cable of the REMOTE plug as illustrated.
- Connection 1 at one end of the resistance.
- Connection 2 at the centre sliding contact of the resistance.
- Connection 3 at the second end of the resistance.
2. Switch off the switched-mode power supply and then connect the REMOTE plug to the rear remote connection.
Screw the external fastening ring.
3.
Slide the rear VOLTAGE REMOTE switch to
the “ON” position.
4. Switch the switched-mode power supply on. The desired output voltage can now be set through the external poti.
Control the complete adjustment area for correct function.
5. If this remote control function is no longer desired, move the switch to the “OFF” position

Enable and disable the output
You can use Port 7 and 8 to remote control the output on/off.
•
Open Port 7 and 8 if you want to enable the output (default).
•
Short Port 7 and 8 if you want to disable the output.
