Section 2: Installation
Note:
No module can be more than 1000 ft / 305 m (in wire length) from the panel.
Do not use shielded wire for
Corbus wiring.
Figure 2-19 Corbus wiring
Module (A) is wired correctly as it is within 1000 ft / 305 m of the panel, in wire distance. Module (B) is wired correctly as it is
within 1000 ft / 305 m of the panel, in wire distance. Module (C) is NOT wired correctly as it is farther than 1000 ft / 305 m
from the panel. For models that require more than 1000 ft / 305 m from the main panel, a HSM3204CX power supply/Corbus
extender can be used.
