Connect the Power
All LCR 600 shipments typically include a 40' gray power cable (100', and 300' are also available) and a 5 A fuse.
Page 17 describes the best practices for routing the gray power cable to the truck cab's accessory panel.
40' Gray PoWer Cable
The gray power cable (PN 84046) is prewired to the J8 and J9 terminals on the display CPU board and the J6
terminal on the CPU board at the factory. It includes two 16AWG wires and a ground drain wire. The 5 A fuse should
be spliced into the red 16 AWG wire as close to the power source as possible.

Power must be supplied to the Epson printer as well. A 15' cable with a 12/24 VDC converter (825001) for printer
power supply is also available. The red wire of this cable must be spliced into the red wire of the gray power cable on
the LCR 600 side of the 5 A fuse.
To connect power to the lCr 600 and the epson printer:
1. Route the gray power cable to the accessory panel. See
page 17
2. Splice the red wire from the printer power cable into the
red wire of the gray power cable.
3. Splice the 5 A fuse into the red wire. Make the splice
close to the direct power terminal connection in the
accessory panel and on the power side of the splice
made with the printer power cable.
Power Check
After the LCR 600 has been installed, check to make sure that it powers up correctly. The LCR 600 display and the
printer power light should come on when the truck's ignition is turned to the ON or to the ACC position. Make sure the
printer power switch is on. If the LCR 600 or the printer does not power up, check the wiring and the connections on
the LCR 600 CPU board against the manual.

4. Connect the red wire to the direct power supply terminal
in the accessory panel.
5. Connect the black wire of the gray power cable to a
reliable DC ground.
6. Connect the black wire of the printer power to a reliable
DC ground.
7. Tape the green drain wire of the gray power cable back
against the power cable.
