Power Supply to the Low Ambient Kit
Power supply mode: Connect the outdoor unit terminals to the low ambient kit.
Connect the brown cable to the L phase of 220 V AC and the blue cable to the N
phase of 220 V AC.
The brown cable and blue cable are two-core low-temperature-resistant cables
delivered with the low ambient kit. The length is 5 m.
If the delivered 5 m cable is not long enough, use a welding iron to welding the
cable and the extension cable, and then use heat shrink tubing to protect the
cable. (The cable must be connected indoors.)
