6.2 Indoor unit system wiring
1. Individual power supply (without power supply device)
(See the table below)
Table 6-1
Fig.5-14
CAUTION
Wiring diameters and continuous lengths in the table are the
situation that voltage decrease degree is within 2%, when the
wiring continuous length exceeds the values in the table, choose
the wire diameter according to regulations
CAUTION
Please select power source for indoor unit and outdoor unit
respectively.
The power supply has specified branch circuit with leakage
protector and manual switch.
The outdoor unit model which corresponding to different outdoor
unit power supply should refer to the nameplate.(Please set all
