Wire ConnectionTables
This appendix provides a tabular description of the wiring connections made to each LCR-II terminal block. It should
be referenced in the event wiring inadvertently mis-routed in the field, or for general troubleshooting in the event of a
problem.
NOTE: Jumper J10 on LCR-II circuit board must be set
for RS-232 communication protocol.
* For a standard RS-232 terminal (other than the Lap
Pad), the black wire is connected to J3-47.
NOTE: Jumper J10 on LCR circuit board must be set for
RS-485 communication protocol.

*On free-end of cable, cut off foil shield and drain wire,
then insulate by taping.
NOTE: The LCR-II Power cable kit includes a fuse holder
and 5 Amp fuse to protect the system in the event of a
short circuit in the cable. Liquid Controls recommends
that this fuse be used in all installations not having a
fused accessory block to protect the truck in the event of
cable faults. A 5 Amp fuse is required.
