Transmission wiring
•
For multi system:
1
Transmission wiring between outdoor units in the same piping
system must be connected to terminals Q1 and Q2 (TO MULTI
UNIT).
Connecting the wires to the F1, F2 (TO OUT/D UNIT) terminals
results in system malfunction.
2
Wiring to other systems should be connected to terminals F1 and
F2 (TO OUT/D UNIT) on the printed circuit board of the master
unit. The outdoor unit that connects transmission wiring to indoor
unit is the master unit. The others are sub unit.
9 .5 . Power wiring connection procedure
•
Be sure to connect the power supply wiring to the power supply ter-
minal block and hold it in place using the included clamp as shown
in the figure below.
•
The L1, L2 and L3 phases of the power wiring should be secured
separately to the hook using the included clamp (1).
•
The ground wiring should be bound to the power wiring using the
included clamp (1) to prevent outside force from being applied to the
terminal area.
