6.3 Electrical Wiring
The electrical wiring connection for the
Switch Box
is shown in Figure 6.1.
(1)
Turn OFF the main power switch and take off the electrical box cover of
Switch Box.
(2)
Connect the power supply wiring to L1 and L2 on the terminal block TB1, and connect ground wiring to
the
terminals in the electrical box.
(3)
Connect the communication cable between the outdoor unit and
Switch Box
to TB2 of the
Switch Box.
(4)
Tightly clamp the wires using the cable clamp inside the electrical box.
(5)
Make sure the communication cables outside the electrical box does not touch sharp edges by
securing with
clamp (accessory (7)).
(6)
Attach the electrical box cover after completing the wiring work.
NOTE:
The
accessory
numbers
are
listed
in
Table
4.1.

Connect
the communication cable between the
Switch Box
and indoor unit to TB3 and TB4 of
the Switch Box.
Ensure that the communication cable between the
Switch Box
and indoor unit
is connected to the
same
letter as piping connection .<Tightening Torque: 1.0 to 1.3 N.m (0.7 to 1.0 ft-lbs)
