PARALLEL OPERATION WITH ISOLATED ANALOG OPTION
Setting Up The Master Unit
8.5.1
Setting up the Power Supply for 0-5/0-10V Isolated Programming and Monitoring.
Perform the following procedure to configure the power supply:
1. Press the power supply AC Input power switch to the
OFF
position.
2. Connect a wire jumper between J1-8 and J1-12 (refer to Table 4-4).
3. Set DIP-switch SW1-1 to the
UP
position for Output voltage external programming and SW1-2 to
the
UP
position for Output current limit external programming.
4. Set SW1-3 to select the Programming Voltage Range:
DOWN
= 0-5V,
UP
= 0-10V.
5. Set SW1-4 to select the Monitoring Voltage Range:
DOWN
= 0-5V,
UP
= 0-10V.
6. Ensure that SW1-7 and SW1-8 are in the
DOWN
position.
7. Connect the programming sources to the mating plug of the
Master
Isolated Programming
connector. Observe for correct polarity of the voltage source.
Setting Up The Slave Unit
8.5.2
