● The onsite grounding resistance must comply with related standards.
● When the NetCol8000-A045/A055/A060 indoor unit is used, prepare one group
of outdoor unit cables for each indoor unit (if two indoor units are used,
prepare two groups of outdoor unit cables). When the NetCol8000-A090/120
indoor unit is used, prepare two groups of outdoor unit cables for each indoor
unit.
● Shielded cables cannot be used as power cables for outdoor units.
● The signal cable is a shielded cable, and the shield layer must be reliably
grounded. Otherwise, device communication is
aected.
The cable diameter must comply with local cable standards. The factors that
aect cable selection include the rated current, cable type, routing mode, ambient
temperature, and maximum expected line loss. Signal cables must be routed
through protective tubes for protection.
