7. OUTDOOR UNIT WIRING
(1) Before starting work, check that
power is not being supplied to
indoor unit and the outdoor unit.
(2) Match the terminal block numbers
and connection cord colors with
those of the indoor unit side.
Erroneous wiring may cause burning
of the electric parts.
(3) Connect the connection cords firmly
to the terminal block. Imperfect
installation may cause a fire.
(4) Always fasten the outside covering
of the connection cord with cord
clamps. (If the insulator is clamped,
electric leakage may occur.)
(5) Always connect the ground wire.
(1) The power cord is not supplied with
the outdoor unit. Use 2.5 mm
mm H07RN-F or equivalent as the
2
connection cord.
(2) Use VW-1, 12 mm diameter, 0.5 to
1.0 mm thick, PVC tube as the insu-
lation tube.
(1) Remove the outdoor unit terminal cover.
(2) Process the end of the connection cords to the
dimensions shown in Fig. 27 and bend the end of
each cord as shown in Fig. 26.
(3) Connect the end of the connection cord fully into the
terminal block and fasten with the screws.
(4) Fasten the sheath with a cord clamp.
