ELECTRICAL WIRING
Outdoor Unit Electrical Connections
Connecting Outdoor Unit Electrical Wiring
The general guidelines for connecting electrical and communication cables to the outdoor unit are the same for each of the Single Zone Wall
Mount units, however, the actual connections on the terminal block will differ. See each illustration for the Single Zone unit model that you are
installing for correct wiring of each terminal block.
• Be sure that main power to the unit is completely off before proceeding with these steps. Follow all safety and warning information out-
lined at the beginning of this manual. Failure to do so may cause bodily injury.
• Be sure that a circuit breaker or some other emergency power cutoff device is in place before any power wiring is done to the system.
Failure to do so, may cause bodily injury or death.
•
Never touch any power lines or live cables before all power is cutoff to the system. To do so, may cause bodily injury or death.

Procedure
Refer to Figure 99 for an example of how a circuit breaker should be wired through to the Single Zone system.
• Be sure there is no power going through the Single Zone system before proceed-
ing with these connections as it may result in electric shock.
• Familiarize yourself with the location of the circuit breaker and be sure that all
power is cut to the Single Zone unit as it may result in electric shock.
1. Using a phillips head screwdriver, remove the conduit panel cover from the
outside unit.
2. Before proceeding, inspect all wiring inside the casing to be sure they are
secure and have not come loose during transportation and installation of the
outdoor unit.
• Loose wires can cause the wiring to burn out quickly.
• Inspect wires for any damage or cracks (manufacturing defects).
3. Confirm that electrical power supply capacity is sufficient to run the unit.
See specifications sheets at the beginning of this installation manual for
details on power.
4. Confirm that you are using the right gauge size for wiring to proceed.
5. Using a screwdriver, connect the wires as shown in Figure 100.
• Figure 100 shows the connections for the HLV models, however the basic
connection procedure is the same for all models. Use this diagram as a
general reference on connecting the power cables.
• Each wire should be securely attached to the terminal block.
• Bundle the cabling by using a cable restrainer.
• Pay attention to the location/connection of the green/yellow grounding cable;
as in some models the connection may be located to the side of the actual
terminal block.
• Maintain a minimum of .2” of wire length from terminal block to cable bundle.
