2-7.5. Grounding
Proper system grounding is an extremely important part of the system installation. As with the AC
power, the grounds for all system components should return to the same circuit breaker panel. This
helps you assure a common ground throughout the system, necessary for protection of the RS-485
data loop circuitry. Ground for all system devices should be wired to the breaker panel ground bus
bar, which in turn should be grounded to a ground rod. A conduit ground does not provide sufficient
ground. It is recommended that the neutral and ground bus bars be bonded together when it is not
prohibited by local codes.
See Figure 2-6 and Figure 2-7 for grounding requirement diagrams of station with mechanical
pump and with electronic pump, accordingly.
CFN PLUS includes several grounding studs (see Figure 2-8 ) in order to comply with the grounding
requirements. The Mains power ground wire should be attached to the stud close to the Line Filter.
