*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 remove 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.
