Mitsumi electronic 55K, FR-F520-0.75K instruction manual Changing the control logic

INSTALLATION AND WIRING

(3) Changing the control logic

The input signals are set to sink logic for the Japanese and NA version, and to source logic for the EC version.

To change the control logic, the 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 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 connector from the rear surface of the control circuit terminal block and place in required Logic position (either Sink or Source).

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

Note: 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 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.
