The transmission wiring inside the EL.COMPO.BOX should be secured using the clamp (1) as shown in next
figure.
1. In the EL.COMPO.BOX
2. Retain to the EL.COMPO.BOX with the accessory clamp (1).
Outside the units, the transmission wiring must be finished simultaneously with the local refrigerant piping, and
wound with tape (field supply) as shown in next figure.
1. Liquid pipe
2. Gas pipe
3. Transmission wiring
4. Insulation material
5. Finishing tape
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 PC-board of
the master unit. The outdoor unit that connected transmission wiring to indoor unit is the master unit. The
others are sub unit.
Caution
Do not connect the power wiring to terminals for the transmission wiring. Doing so would destroy the entire
system.
When connecting wires to the terminal block on the PC-board, too much heat or tightening could damage the PC-
board. Attach with care.
See the table below for the tightening torque of the transmission wiring terminals.
Screw size Tightening torque (N · m)
