Verifying the Installation

•

Do not pull cables J1, J2, J3, and J4 and their terminals casually. Ensure that the cables

are connected securely.

•

If there are only two smart cooling products in the converged cabinet, you only have to

connect cables 3, 4, and 10, since other cables are factory-installed. If there are three

smart cooling products, all cables except 1 to the third smart cooling product have to

be connected onsite.

•

The length of signal cable for the indoor and outdoor units cannot exceed 200 meters.

•

The signal cable should be shielded, and the shield layer shall be grounded.
