*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 heat source 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.
*7.Refer to the Data book for wiring terminal block for
Pump Interlock and Operation ON signal.
