plug location.
b) LM05 Hoist Body:
Remove wire #5 from the X1:5 terminal strip*.
Remove wire #9 from the X1:9 terminal strip*.
LM10, LM16, LM20; LM25 Hoist Body:
Remove wire #5 from A2 on the K10 contactor*.
Remove wire #9 from the X1:9 terminal strip*.
*These wires should all be connected to the X23 plug.
2. On the LM05 remove the F100 transformer fuse.
3. On the LM05 add the mainline power feed to the load side of the K10 contactor. On the
