*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 removed them.
*6.Control box houses high-voltage parts.
Before inspecting the inside of the
control box,turn of
f the power
,keep the
unit of
f for at least 10 minutes, and
confirm that the voltage between
TB-P
and
TB-N on INV Board has dropped to
DC20V or less.
