Connecting the Power Cable to a Water-Cooled Module

(Optional) Connecting the Signal Cable Between Outdoor and Indoor

Units

8.4

(A) Core wire

(B) Insulation layer

(C) Shield layer (D) Jacket

•

The figure uses the NetCol8000-A045
as an example. If the indoor unit is
NetCol8000-A090 or NetCol8000-
A120, connect the outdoor unit signal
cable to X503 terminals 1, 2, and 3, or
5, 6, and 7 of the indoor unit.

•

Air-cooled outdoor unit: The shield
layer must be routed through the
buckle and crimped properly.

•

Water-cooled module and indoor
unit: The shield layer must be reliably
connected to the nearby PE point.
