All field-supplied wiring, components, and materials should follow national, state, and local codes and requirements.
Use only stranded, shielded copper conductor.
Ground wiring is required to prevent accidental electrical shock during current leakage, communication problems from electrical
noise, and motor current leakage. Do not connect the ground line to the pipes.
Install a main shutoff switch or circuit breaker that interrupts all power sources simultaneously.
Wiring cable size must comply with applicable national, state, and local codes.
