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

r

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 

KPVJGƂIWTGDGNQY

r

The L1, L2 and L3 phases of the power wiring should be secured 
separately to the hook using the included clamp (1).

r

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.

r

Use an appropriate screwdriver for tightening the terminal screws. 
A screwdriver with a small head will strip the head and make proper 
tightening impossible.

Over-tightening the terminal screws may break them.

When 2 wires are connected to a single terminal, connect them so 
that the rear sides of the crimp contacts face each other. Also, make 
sure the thinner wire is on top, securing the 2 wires simultaneously

r

Wire so that the ground wiring does not come into contact with the 
compressor lead wiring.
If they touch, this may have an adverse effect on other devices.

The transmission wiring must be at least 2 in. (51 mm) away from 
the power wiring.
