capability for an XW Power System. The System Control Panel:

• Monitors activity throughout your power system

• Displays the settings and status of each Xanbus-enabled device

• Enables you to adjust settings for each Xanbus-enabled device.

The System Control Panel uses Xanbus™, a network communications
protocol developed by Xantrex, to communicate its settings and activity
to other Xanbus-enabled devices.

Xanbus-enabled products are:

• Easy to use. The Xanbus network simplifies operation and automates
routine tasks.

• Reliable. Software control eliminates errors due to analog signaling.

• Accurate. Digital information is less susceptible to interference and
line loss.

Important:

System components, including XW Hybrid Inverter/Chargers, XW-MPPT
Charge Controllers, and the XW Automatic Generator Start.

The XW System Control Panel is compatible only with XW

System
requirements

Operational
Features

The System Control Panel requires a Xanbus power supply to operate.
Network power is carried by the network cables, and can be supplied by
an XW Hybrid Inverter/Charger or an external Xanbus power supply.

As a device that draws network power, the System Control Panel
consumes a maximum of 3 watts.

Other features of the System Control Panel include:

• Compatibility—connect additional Xanbus-enabled XW System
devices without requiring additional device-specific control panels.

• Internal clock—keeps time for the entire system.

• Audible alarm—if enabled, alerts you when a fault condition arises.

• Low power consumption—automatically turns off the backlight after
a period of inactivity.

Installation

Chapter 2 contains information and procedures for
planning and performing a XW System Control Panel
installation, including:

• Materials and tools required

• Choosing a location

• Choosing a network layout

• Mounting the unit

• Connecting the System Control Panel to other
devices.

Installation

Installing the XW System Control Panel

The XW System Control Panel is designed to be wall moun ted (see
“Mounting the System Control Panel” on page 2–11), and requires no
connections other than Xanbus ne twork cables o r a terminator plug ged into
the back of the unit.

Because you cannot access the System Control Panel network inputs once
the unit is mounted, the Xanbus cables must be routed through the wall
and connected before securing the System Control Panel.

Materials and Tools Required

The following materials and tools are required to complete the
installation:

p Mounting template sticker (supplied)
p Mounting plate (supplied)
p Mounting bracket (supplied)
p Four #6 screws (supplied)
p Two #8 screws (supplied)
p Cable clamps or hardware fasteners
p Xanbus network cables or equivalent (CAT 5 or CAT 5e cable with

RJ-45 connectors wired to T568A standard. One 7 foot/2.1 meter
cable is supplied)

p Two network terminators (one male terminator is supplied with each

Xanbus-enabled device, but termination requirements vary with
network layout)

p Phillips head screwdriver
p Jigsaw or small keyhole saw
p Power drill with 1/8" bit (optional)

Choosing a Location

Choose a location that allows unobstructed access to the System Control
Panel screen and buttons.

The location should be indoors, dry, and free from corrosive or explosive
fumes.

2–2 975-0298-01-01

WARNING: Explosion hazard

The System Control Panel is not Ignition Protected. Do not install in areas
requiring Ignition-Pr ot ected equipment, such as areas containing gasoline
engines, tanks, or fuel-line fittings.

Network Installation

This section describes requirements for installing the System Control
Panel as part of a Xanbus network-managed power system. For the
system to function properly, requirements for network layout and
termination must be followed.

Network Components

A Xanbus network consists of the following components:

Network Installation

• Xanbus-enabled devices—these include the System Control Panel,
the XW Series Inverter/Charger, XW-Automatic Generator Start
(AGS), and XW Charge Controller. The network can consist of up to
eight Xanbus-enabled devices. A typical XW Power System can
include three inverter/chargers, two charge controllers, one AGS and
one System Control Panel. Only one System Control Panel can be
installed on the Xanbus network.

• Xanbus power supply—the network requires a power supply ca pable
of providing 15 Vdc/200 mA to each device. The XW Series Inverter/
Charger provides network power, but if no inverter/charger is
installed, an external power supply is required. Contact Xantrex for
more information.

• Xanbus cables—each Xanbus-enabled device is connected by a
Category 5 (CAT 5 or CAT 5e) cable. The cable consists of eight
conductors in four twisted pairs with an RJ-45 modular connector
wired to the T568A standard. See Figure 2-2 on page 2–4. A 7 foot
(2.1 meter) network cable is included with the System Control Panel.
If more cables or a different length are required, these standard cables
can be purchased from Xantrex or any computer supply store.

CAUTION: Equipment damage

Do not use crossover cable.

Figure 2-2

RJ-45 Connector

• Network terminators (Figure 2-3)—the Xanbus network must be
properly terminated at each end with male or female network
terminators to ensure the communication signal quality on the
network. If the network is not properly terminated, signal quality is
degraded and performance on the network is reduced. Permanent
configuration without terminators is not supported by Xantrex. The
System Control Panel ships with one male terminator already
installed. Depending on your network layout, this terminator may
need to be removed and inserted into another device elsewhere in the
network.

2–4 975-0298-01-01

Network Installation

Male network terminator Female network terminator

Figure 2-3

Network Terminators

• Network connectors (optional, depending on network layout)—the

three-way connector houses three RJ-45 inputs that provide a device
connection point on a multi-drop backbone layout (see “Multi-Drop
Backbone Layout” on page 2–6). All three inputs are wired
identically and can accept either Xanbus cables or terminators. One
input is available for connecting to a Xanbus-enabled device. The
remaining inputs are reserved for connection to other network
connectors, a Xanbus cable terminated with a female terminator, or a
male terminator.

The network connector is mounted to a bulkhead or a wall, as shown
in Figure 2-4.

Network Components and Part Numbers

Xanbus-enabled devices can be connected in one of two Xanbus System
layouts: multi-drop backbone or daisy chain. Each network layout has
advantages and disadvantages, depending on the application and/or
environment. It is up to you or your system designer to decide which
layout is best for your installation.

Important:

configurations are not supported by Xantrex.

Multi-Drop Backbone Layout

In a multi-drop backbone layout, each Xanbus-enabled device on the
network is connected by a drop cable to the network bus or backbone
using a network connector, as shown in Figure 2-5.

2–6 975-0298-01-01

Do not mix the two types of network layouts. Mixed

Network Installation

Network terminators are required at both ends of the network, and the
Xanbus-enabled devices do not require their own termination.

If cables are placed at the end of the network, female terminators are
required. Otherwise, male terminators must be inserted directly into the
open input of each network connector at the end of the network.

Advantages In this layout, Xanbus-enabled devices can be removed or
replaced while still keeping the network operating.

Disadvantage The main disadvantage of this layout is the cost of the
network connectors (a daisy chain layout uses no network connectors).
Each device in this layout requires its own network connector.

In a daisy chain layout, each device on the network is linked with separate
lengths of Xanbus cable, as shown in Figure 2-6. This layout does not
require network connectors.

As in the multi-drop backbone layout, two terminators are required to
ensure the communication signal quality on the network. The Xanbus­enabled devices at each end of the chain must have a male terminator
inserted into their open network inputs.

Advantage The advantage of this layout is that it is less expensive to
install because network connectors are not required.

975-0298-01-01 2–7

Installation

Disadvantage The disadvan tag e of the daisy chain layout is that
Xanbus-enabled devices cannot be removed from the network without
interrupting the network. To make the network function after removing a
device, you must connect the Xanbus-enabled devices on either side of
the missing device to each other or replace the device.

Guidelines for Routing the Xanbus Cables

WARNING: Shock hazard

System Control Panel

System Control Panel II

:

Do not route the Xanbus cables in the same conduit or panel as the AC and DC
power cabling.

To ensure maximum performance of your network, follow these
guidelines when routing the Xanbus cables. Route the cables before
installing the System Control Panel.

• Route the cables away from sharp edges that might damage the
insulation. Avoid sharp bends in the cable—no less than a 4-inch
(100 mm) radius.

• Allow at least 2 ¼ inches (57 mm) of space behind the wall to
accommodate the depth of the unit and allow room for the cables to
bend.

• Allow for some slack in the cable tension.

2–8 975-0298-01-01

• Keep the alignment of wire pairs inside the sheath as straight as

possible.

• Allow separation between data and power cables (data cables should

only cross a power cable at right angles).

• Do not staple the cable with metal cable staples. Use appropriate

hardware fasteners to avoid damage to the cable.

The total length of the network, including all connected Xanbus-enab l ed
devices and the System Control Panel, cannot exceed 130 feet (40 m).
Xanbus cables are available in lengths from 3 feet (0.9 m) to 75 feet
(22.9 m).

Connecting Xanbus Cables

Follow these guidelines for connecting Xanbus cables to the System
Control Panel. The cables are connected to the System Control Panel at
the same time the System Control Panel is mounted. Read “Mounting the
System Control Panel” on page 2–11 before performing the following
procedures.

Network Installation

CAUTION: Equipment damage

:

Connect the System Control Panel only to other 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 connecting a Xanbus system directly to a personal
computer.

CAUTION:

Do not connect one end of the network to the other to make a ring or loop.
