Notes (1) “None” means that jumper wire is not provided on the PCB or the connection is cut

(2)The replacement board is not equipped with jumper wires JA1~JA8. Instead, SW4 and 6 are mounted in the same position and have the same functions as jumper wires JA1~JA8. Carry out the local settings in accordance with the above table using SW4 and 6.

Notes (1) “None” means that jumper wire is not provided on the PCB or the connection is cut

(2)The replacement board is not equipped with jumper wires J11~J13. Instead, SW3 is mounted in the same position and has the same func- tions as jumper wires J11~J13. Carry out the local settings in accor- dance with the above table using SW3.

(3)The overcurrent setting value becomes the above setting value (A) automatically in accordance with the settings on J11(SW3-1) ~ J13(SW3-3) and J1(SW4-1).
