The general guidelines for the electrical and communication cables to the outdoor unit are the same for
each system. However, the actual connections on the terminal block will differ. Refer to each figure for the
model you are installing for the correct wiring of
each terminal block.
1. Using a Phillips-head screwdriver, remove the conduit-panel cover from the outside of the unit.
2.Inspect all wiring inside the casing to make sure that they are secure and have not come loose during
transportation and installation.
• Loose wires
can cause the wiring to burn-out quickly.
•Inspect wires for damage or cracks (manufacturing defects).
3. Confirm that the Electrical power-supply capacity is sufficient to run the unit. Refer to the specifications
in 2.1 - Electrical Data.
4. Confirm that you are using the correct wire gauge
size to proceed.
