3.7 WIRING CONNECTIONS
Make connections to the 10’ cable, which is supplied by ONICON and is pre-wired to the circuit
board.
The most common cause of electronic failures are miswired connections. If you are adding
additional cable, please record any substitution of wire colors. If additional cable is purchased
from ONICON, the color code can be maintained. Cable from other sources will most likely have a
different set of colors. Please refer to Appendix A for wiring diagrams and factory color codes.
Only qualified service personnel should make connections between the flow meter and the user’s
external equipment. Any misapplication of power and/or ground can result in improper operation
or damage to the flow meter circuitry, and to any externally connected equipment.
