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