*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.
