*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.
