Connecting Xantrex Xanbus-Enabled Devices
To connect the Xantrex Xanbus-enabled devices:
1. Determine and prepare the location for each device. Refer to the installation
instructions for each device.
2. Determine and measure the required cable length, taking into consideration
the network layout, the routing, and strain relief requirements. Do not exceed
the total recommended cable length of 40 m.
3. Mount the devices according to the installation instructions for each device.
4. Use an appropriate length of Xantrex Xanbus cable to connect each device.
5. Insert a terminator into the open network port of the Xantrex Xanbus-enabled
device at each end of the network. See Figure 2-7.
Connecting AC Sync Cables
Connect AC Sync cables in the same daisy-chain layout as Xantrex Xanbus
network cables (see Figure 2-7). Network terminators are not required for AC
Sync connections.
To install the AC Sync cables:
1. Insert the cable into one of the two AC Sync ports in inverter #1.
2. In a two-inverter system, connect the AC Sync cable between inverter #1 and
inverter #2.
In a three-inverter system, connect an AC Sync cable between inverter #1
and inverter #2, and then connect another AC Sync cable between the
second AC Sync port in inverter #2 and an AC Sync port in inverter #3.
Important: Installing and replacing Xantrex Xanbus-enabled devices in an
existing system must be performed with the Xantrex XW Power System in
Standby mode. For more information about Standby mode, see the Xantrex XW
System Control Panel Owner’s Guide.
CAUTION: Equipment Damage
Connect only to other Xantrex Xanbus compatible 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 Xantrex Xanbus to different
systems.
