*1. Single-dotted lines indicate wiring not supplied
with the unit.
*2. Dot-dash lines indicate the control box boundaries.
*3. Refer to the Data book for connecting input/output
signal connectors.
*4. Daisy-chain terminals (TB3) on the outdoor units in the
same refrigerant system together.
*5. Faston terminals have a locking function.
Make sure the terminals are securely locked in place
after insertion. Press the tab on the terminals to
removed them.
*6. Control box houses high-voltage parts.
Before inspecting the inside of the control box,turn off
the power,keep the unit off for at least 10 minutes, and
confirm that the voltage between FT-P and FT-N on
INV Board has dropped to DC20V or less.
