• 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.
