3.8.7 Foldback Check

WARNING
Shorting the output may expose the user to hazardous
voltages. Observe proper safety procedures.
Refer to Section 5.5 for explanation of the FOLD function prior to performing the procedure
below.
1. Ensure that the output voltage is set to approx. 10% of the unit rating.
2. Adjust the CURRENT encoder to set the current limit to approx. 10% of the unit rating.
3. Momentarily press the FOLD button. Ensure that the FOLD LED illuminates. The output
voltage remains unchanged.
4. Short the output terminals momentarily (approx. 0.5 sec.). Ensure that the output voltage falls
to zero, the VOLT display shows "Fb" and the ALARM LED blinks.
5. Press the FOLD button again to cancel the protection. The output voltage remains zero.
6. Press OUT button. Ensure that the output voltage returns to it's last setting.
7. Turn the output off by pressing OUT button. Ensure that the VOLT display shows "OFF".

3.8.8 Address Setting

1. Press and hold the REM/LOC button for approx. 3sec. The VOLT display will show the
communication port address.
2. Using the VOLT adjust encoder, check that the address can be set within the range of 0 to 30.

3.8.9 Baud Rate Setting

1. Press and hold the REM/LOC button for approx. 3sec. The CURRENT display will show the
communication port Baud Rate.
2. Using The CURRENT adjust encoder, check that the Baud Rate can be set to 1200, 2400,
4800, 9600 and 19200.

3.9 CONNECTING THE LOAD

WARNING
Turn off the AC input power before making or changing any
rear panel connection. Ensure that all connections are
securely tightened before applying power. There is a
potential shock hazard when using a power supply with a
rated output greater than 40V.

3.9.1 Load Wiring

The following considerations should be made to select wiring for connecting the load to the power
supply:
* Current carrying capacity of the wire (refer to 3.9.2)
* Insulation rating of the wire should be at least equivalent to the maximum output voltage of
the power supply.
* Maximum wire length and voltage drop (refer to 3.9.2)
* Noise and impedance effects of the load wiring (refer to 3.9.4).

3.9.2 Current Carrying Capacity

Two factors must be considered when selecting the wire size:
1. Wires should be at least
current at the rated load, or the current that would flow in the event the load wires were
shorted, whichever is greater.

WARNUNG
ß
Das Kurzschlie en des Ausgangs kann den Anwender
ä
einer gef hrlichen Spannung aussetzen. Beachten Sie
die entsprechenden Sicherheitsrichtlinien.
WARNUNG
Schalten Sie die Netzversorgung aus, bevor Sie
Verbindungen an der Rückseite des Gerätes vornehmen
oder ändern. Stellen Sie sicher, dass alle Verbindungen fest
und sicher sitzen, bevor Sie das Netz einschalten.
Bei Stromversorgungen mit einer Nennausgangsspannung
von mehr als 40V besteht grundsätzlich die Gefahr eines
elektrischen Schlags.
