3.8.7Foldback 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 Output Current setting 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 the OUT button. Ensure that the Output Voltage returns to its last setting.

7.Turn the output off by pressing the OUT button. Ensure that the VOLT display shows “OFF”.

3.8.8Address Setting

1.Press and hold the REM/LOC button for approx. 3 sec. 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.

3.8.9Baud Rate Setting (RS-232 and RS-485 only)

1.Press and hold the REM/LOC button for approx. 3 sec. 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 tight- ened before applying power. There is a potential shock hazard when using a power supply with a rated output greater than 40V.

3.9.1Load 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 Section 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 Section 3.9.2)

∗Noise and impedance effects of the load wiring (refer to Section 3.9.4).

3.9.2Current Carrying Capacity

Two factors must be considered when selecting the wire size:

1.Wires should be at least heavy enough not to overheat while carrying the power supply load current at the rated load, or the current that would flow in the event the load wires were shorted, whichever is greater.
