1.3 Computer Wiring
The RCI 510 System is based on the original wiring done by the factory. Greer Company cannot
assume responsibility for color codes used on wiring done at the time of origin.
We have identified the wiring inside and outside of our computer to assist with the installation. It is the
responsibility of the installer to properly identify the correct wires and routings on the crane for
connections to the MG510 computer. Please reference the wiring diagram below.
*NOTE: The Green wire may have been replaced by a jumper wire inside the MG400 computer from
B+ to Relay 2 C. In this case, use a jumper wire from BLD 3 to BLD 7.
