Connecting Network Cable Between Multiple Units
Single knockouts on the back and bottom of the solar charge controller are
provided for routing the Xanbus network cables. See Figure 2-4. See Figure 2-9
for the location of the solar charge controller Xanbus ports.
To connect network cables between multiple units:
1. Remove the wiring compartment cover from each unit.
2. Remove a single knockout from the back or bottom of each solar charge
controller.
3. Connect the network cable to a Xanbus port in solar charge controller #1.
4. Route the cable to solar charge controller #2.
5. Connect the network cable to a Xanbus port in solar charge controller #2.
6. Connect another network cable to solar charge controller #2 and route the
cable to the next device in the network.
7. Ensure the factory-supplied network terminators are inserted into the empty
Xanbus ports in the devices at the beginning and end of the network. There
should be no empty Xanbus ports in any of the solar charge controllers.
WARNING
ELECTRICAL SHOCK HAZARD
Do not route the network cables in the same conduit or panel as the DC input/
output cables.
Before opening the solar charge controller wiring compartment, ensure the PV
array and batteries are disconnected. To reduce the risk of shock, cover the
array with an opaque (dark) material.
Failure to follow these instructions can result in death or serious injury.
NOTICE
EQUIPMENT DAMAGE
Connect only Xanbus-enabled devices. Although the cabling and connectors
used in this network system are the same as ethernet connectors, this network
is not an ethernet system. Equipment damage may result from attempting to
connect the solar charge controller to different systems.
Do not connect one end of the network to the other to make a ring or loop to
avoid unpredictable device behavior.
Failure to follow these instructions can damage the equipment.
