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 (G8 or later) 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
FT
-P
and FT
-N on INV Board has dropped
to
20VDC
or
less.
*7.
Refer to the Data book (G8 or later) for
wiring terminal block for Pump Interlock (TB8).
