• All field-supplied wiring, components, and materials must comply with all applicable national, state, and local codes and requirements.
Improper wiring will result in fire, electric shock, causing physical injury or death.
• Ground wiring is required to prevent accidental electrical shock during current leakage, communication problems from electrical noise, and
motor current leakage. 'RQRWFRQQHFWWKHJURXQGOLQHWRWKHSLSHV7KHUHLVDULVNRI¿UHHOHFWULFVKRFNH[SORVLRQUHVXOWLQJLQSK\VLFDO
injury or death.
• Install a main shutoff switch or circuit breaker that interrupts all power sources simultaneously. There is a risk of fire, electric shock, explo-
sion, resulting in physical injury or death.
• Terminal block labels, appearances, and location will vary depending on outdoor unit model.
• Maintain polarity throughout the communication network. The system will malfunction if not properly wired.
NOTE
• All field-supplied wiring, components, sizes, and materials must comply with all applicable national, state, and local codes and require-
ments. Failure to install proper electrical components can result in property damage and equipment malfunction.
• Ground wiring is required to prevent communication problems from electrical noise, and motor current leakage. Failure to provide proper
ground wiring can result in property damage and equipment malfunction.
• Install a main shutoff switch or circuit breaker that interrupts all power sources simultaneously. Failure to install proper electric components
will result in property damage and equipment malfunction.
