Connecting indoor unit power wire (single power supply)
Step 1
At the rear of the top/bottom of the indoor unit cabinet, use needle-nose pliers to remove the
knocking-piece at the top/bottom of the cabinet; remove the cable gland from the accessory
package and remove its nut. Rotate and tighten the cable gland on the knocking-piece, and
pass the power wires through it.
(Figure 3-15: In-coming Power Cable Path (Single Power Supply))
Step 2
Pass the external wire through the cable connector to the indoor unit’s Feed A terminal
L1/L2/L3 and fasten it. (Beware of the fact that, when using a single power supply, the power
cable must be connected to the main circuit power source Feed A.)
Step 3
Connect the PE line (Protective Earthling line) to the cabinet ground stud, as shown. It should
be securely locked to prevent injuries from abnormal current.
