Wiring of control circuit
2.13.2 Changing the control logic
The input signals are set to sink logic (SINK) when shipped from the factory.
To change the control logic, the jumper connector on the back of the control terminal must be moved to the other position.
(The output signals may be used in either the sink or source logic independently of the jumper connector position.)
(1) Loosen the two installation screws at the both side of the control circuit terminal block. (These screws cannot be
removed.)
Slide down the standard control circuit terminal block to remove it.
(2) Change the jumper connector set to the sink logic (SINK) on the rear panel of the control circuit terminal block to the
source logic (SOURCE).
(3) Using care not to bend the pins of the converter's control circuit connector, reinstall the control circuit terminal block and
fix it with the installation screws.
NOTE
• Make sure that the control circuit connector is installed correctly.
• While power is ON, never disconnect the control circuit terminal block.
