(4) Changing the control logic

The input signals are factory set to sink logic (SINK).

To change the control logic, the jumper connector on the back of the control circuit terminal block 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 mounting screws in both ends of the control circuit terminal block. (The screws cannot be removed.) With both hands, pull down the terminal block from the back of the control circuit terminals.

2)Remove the jumper connector from the sink logic (SINK) position on the back surface of the control circuit ter- minal block and fit it to the source logic (SOURCE) position.

3)Using care not to bend the pins of the inverter's control circuit connector, reinstall the control circuit terminal block and fix it with the mounting screws.

CAUTION

1.Make sure that the control circuit connector is fitted correctly.

2.While power is on, never disconnect the control circuit terminal block.

3.The sink-source logic change-over jumper connector must be fitted in only one of those positions. If it is fitted in both positions at the same time, the inverter may be damaged.
