Communications Wiring for Multiple Inverters
975-0334-01-01 3–13
Terminators The network terminator supplied with each GT Inverter (Figure 3-12) is required
at each end of the network to ensure the communication signal quality on the
network.
Xanbus ports Two RJ-45 ports are provided in the GT Inverter, accessible from the wiring box.
See Figure 3-13 for the location of these ports.
RJ-11 ports The RJ-11 ports allow the interconnection of multiple inverters for 3-phase
configurations where the requirement is to avoid high unbalanced generating
conditions on the transformer. Any inverter disconnecting from the grid also
forces the remaining inverters offline. This condition remains until grid
parameters for all inverters are within operating specifications.
Cabling Requirements
The network uses Category 5 (CAT5 or CAT5e) cable, a standard cable available
from any computer supply store. The cable consists of eight conductors in four
twisted pairs with an RJ-45 modular connector wired to the T568A standard.
Table 3-2 contains the arrangements of wire colors to pin numbers for the T568A
standard.
