Perform wiring so that water does not enter this unit
along the external wiring. Always install a trap to the
wiring or take other countermeasures. Otherwise it will
cause trouble, electric shock, or fire.
Confirm the name of each unit and name of each
terminal block of the unit and connect the wiring in
accordance with the directions given in the manual so
that there is no incorrect wiring. Incorrect wiring will
damage the electric parts and cause smoke and fire.
When installing the connection cables near a source
of electromagnetic waves, use shielded cable. Other-
wise, a breakdown or malfunction could result.
When wiring between the outdoor unit, indoor unit,
▪
and touch panel controller, refer to the indoor unit and
outdoor unit installation manuals.
Always connect both ends of the
▪
earth (ground) con-
nection of the transmission cable.
Install the disconnect switch to the easily accessible
▪
location.
Install the fuse (5A) to the L line of power supply cable.
