appropriately sized grounding conductors. All installations must comply with
national and local codes. Consult local and national codes for specific
grounding and bonding requirements.
Failure to follow these instructions can result in death or serious injury.
The Conext XW+ is provided with ground terminals that must be reliably
connected to ground (protective earth) by appropriately sized equipment
grounding conductors. System grounding for the AC and DC systems must be
done according to all applicable NEC and local installation codes.
For more information about system grounding, see “Grounding the DC System”
on page 3–8 and “AC Equipment Grounding” on page 3–20.
Grounding the DC System
To connect the Conext XW+ to the DC grounding system, use the ground lug at
the bottom of the Conext XW+ chassis (see “Conext XW+ Features” on page 1–
4). The terminal accepts wires from #14 AWG (1.63 mm) to #2 AWG (6.54 mm).
System grounding for the DC system, which typically involves bonding
(connecting) the battery negative circuit to ground, is dependent on the system
configuration.
Note: If a grounded DC system is required, ensure that the system bonding is
done in one location only, and that all conductors and connections comply with
all applicable NEC and local installation codes.

Battery Temperature Sensor Installation
WARNING
BATTERY TEMPERATURE
The Battery Temperature Sensor provides necessary information for
performance and safety.
Always install and connect the Battery Temperature Sensor (BTS).
Failure to follow these instructions can result in death or serious injury.
The Battery Temperature Sensor (BTS) regulates battery charging based on
battery temperature. The BTS extends battery life by minimizing overcharging in
warm temperatures and undercharging in cold temperatures.
The BTS connects to the Conext XW+ via the BTS port, which is located at the
bottom of the Conext XW+ chassis, next to the communication ports.
Note: Connect the BTS to the batteries only after the battery bank has been
prepared and is ready to connect to the inverter.
To install the Battery Temperature Sensor:
1. Route the BTS cable through your preferred conduit route and insert the BTS
jack into the BTS port.
2. Route the BTS cable to the battery enclosure, and then connect the BTS
using one of the following methods (as shown in Figure 3-6 on page 3–11):
a) Connect the BTS ring terminal directly to a battery terminal
(recommended), or:
b) Attach the BTS to any side of the battery you wish to monitor by using the
adhesive backing on the BTS.
Note: When using the adhesive backing, install the BTS on the side of the battery
below the electrolyte level.

AC System Bonding
WARNING
MULTIPLE AC NEUTRAL-TO-GROUND BONDS
Verify that only one neutral-to-ground bond exists in the system. Having more
than one neutral-to-ground bond in a system violates local electrical codes,
may create a shock or fire hazard, and may cause some sensitive equipment
to malfunction.
Failure to follow these instructions can result in death or serious injury.
System bonding refers to connection (bonding) of one of the current-carrying
conductors of an electrical system to ground. This creates a "grounded
conductor" or "neutral" that is at ground potential, but is separate from the
equipment ground conductor. System bonding must be done at only one
location. Procedures for system bonding vary between on-grid and off-grid
systems.
System bonding for
on-grid systems
The Conext XW+ does not connect the neutral to ground. The AC input neutral is
already bonded to ground by the incoming utility grid system. Do not connect the
neutral to ground in any additional location.
The Conext XW+ does not switch or disconnect the AC neutral in any mode of
operation, so even in invert (back-up) mode, the inverter load sub-panel neutral
is bonded to ground by the utility grid system. It must not be grounded again in
the inverter load sub-panel.
System bonding for
off-grid systems
In a system without a generator, or with a generator that does not provide a
grounded neutral, you must make the connection from neutral to ground in the
inverter load sub-panel or main distribution panel, as applicable.
In a system with a generator that provides a grounded neutral, no additional
connection from neutral to ground is needed. Do not connect neutral to ground in
the inverter load sub-panel or main distribution panel, as applicable.

To connect the Conext XW+ Power Distribution Panel to the Conext XW+
Inverter/Charger:
1. In the Conext XW+ Power Distribution Panel (PDP), locate the wire labelled
INV1 N-LOAD (SPLIT PHASE), pre-installed in the neutral bus bar N-LOAD
terminal. Connect the INV1 N-LOAD (SPLIT PHASE) wire to the AC Load
terminal (N-LOAD) on the Conext XW+ Inverter/Charger, as shown in Figure
3-12 on page 3–23.
2. Locate the wires labelled INV1 L1-LOAD and INV1 L2-LOAD, pre-installed in
the terminals at the input (top) side of the 60 A, 120/240 VAC, two-pole, type
QOU output AC breaker in the PDP. Connect the INV1 L1-LOAD and INV1
L2-LOAD wires to the AC Load terminals (L1 -LOAD and L2-LOAD,
respectively) on the Conext XW+ Inverter/Charger.
3. Locate the wires labelled INV1 L1-GRID and INV1 L2-GRID, pre-installed in
the terminals at the bottom of the output breaker in the PDP.
4. Connect the INV1 L1-GRID and INV1 L2-GRID to the Conext XW+ Inverter/
Charger, using one of the following methods (depending on your
installation):
•
If the AC source will be the utility grid, connect to the GRID (AC1) terminals
(L1-GRID, L2-GRID) on the Conext XW+ Inverter/Charger. (See Figure 3-12
on page 3–23.)
Note: In an on-grid system with a generator, you will need to install an additional
60 A, 120/240 VAC, two-pole, type QOU AC breaker onto the DIN rail. For
information, see Figure 3-13 on page 3–24.
•
If the system will be off-grid and the only AC source will be a generator,
connect these wires to the GEN (AC2) terminals (L1-GEN, L2-GEN) on the
Conext XW+ Inverter/Charger. (See Figure 3-14 on page 3–25.)
Note: Both lines (L1 and L2) of input power must be connected in order for the
Conext XW+ Inverter/Charger to operate. For example, L1 and L2 of Grid Input
L1 and L2 of Gen Input need to be connected.
Note: Additional neutral terminals (N-GRID, N-GEN) are provided on the Conext
XW+ Inverter/Charger for installations that do not use the XW+ Power Distribution
Panel. For more information, see “Wiring the Conext XW+ Inverter/Charger

Applying DC Power to the Inverter
NOTICE
DC REVERSE POLARITY
Before making the final DC connection or closing the DC breaker or
disconnect, check cable polarity at both the battery and the inverter/charger.
Positive (+) must be connected to positive (+). Negative (–) must be
connected to negative (–).
Failure to follow these instructions can result in damage to equipment.
To apply DC power to the inverter:
1. Before applying DC power to the inverter, measure the voltage and check
polarity at all connections. (Measure at the battery side of the disconnect or
breaker.)
Note: Voltage should be between 40 to 64 volts for a 48-volt system. If the DC
voltage is low, the battery bank must be charged externally. Charge the battery
bank, and then restart the functional test.
If the DC voltage is lower than the Low Battery Cut Out (LBCO) setting (46 volts
for a 48-volt system) a DC Under Voltage Fault (F48) will be triggered. If the DC
voltage is lower than the default LBCO voltage, lower the LBCO setting
accordingly.
2. Apply battery (DC) power to the inverter by closing the battery bank
DC disconnect.
The inverter will power up in standby mode, and the inverter information
panel will display (standby), as shown in Figure 3-16.

3. Monitor the invert (green kW) LED to confirm which mode the inverter is in:
•
kW LED OFF – Invert mode is disabled. The inverter/charger is not
powering the AC loads. However, if good AC is present, it is passed
through to the loads.
•
 displayed on the inverter information panel – The inverter/charger is
in search mode and is looking for an AC load greater than the Search
Watts setting (default = 25 watts). The display shows  (Search)
when this mode has been enabled.
•
LED ON – The inverter/charger is on. The inverter is operating and is
able to provide power to the AC loads. This is the default mode on initial
power-up once the unit is taken out of standby mode.
If the inverter is not operating or the inverter LED (kW) does not turn on, check all
connections. Check the inverter’s DC voltage and polarity on the positive (+) and
negative (–) terminals. Check the Fault LED. If the fault LED is on, check for a fault

code on the information panel. Correct the reported fault and clear the fault by
acknowledging it. If the DC voltage is low, then the battery bank needs to be
charged externally. Charge the battery bank and restart the functional test.
AC Voltage Check
Note: This test requires the use of a voltmeter.
To perform an AC voltage check:
1. With the inverter on (green kW LED is on and steady), verify the AC voltage at
AC Loads block terminal L1-Load to N-Load.
2. Verify that neutral is bonded to ground in the system by measuring the hot
and neutral voltages relative to ground. Neutral-to-ground should equal zero
(0) volts.
3. After confirming the correct AC voltage, turn on your AC output breaker and
place a load on the inverter (plug in a light or other load to an outlet the
inverter is powering).
4. Confirm that the AC load that was just turned on is working properly.
Figure 3-20 Checking AC Voltage
Confirming Battery Charger Operation
To confirm battery charger operation:
1. Apply AC from grid or generator. LEDs will blink while the power source is
qualified.
2. Check LEDs (AC1 or AC2) on the front panel. One of them must be ON for
the unit to charge.
3. Check the amp (A) LED. If the A LED is ON, the unit is charging and the
battery current is displayed on the inverter information panel.

Basic Functional Test - Multiple Inverters
The following steps will complete a basic functional test of multiple Conext XW+
Inverter/Chargers. If any test fails, please refer to the Troubleshooting section in
the Conext XW+ Inverter/Charger Owner’s Guide for assistance.
To perform a functional test on multiple inverters:
1. Check/verify all wiring and cable connections.
2. Measure DC voltage at the DC terminals on the inverter and confirm it is
within range and has correct polarity. The default acceptable range is 46 to
64 VDC for 48 V systems.
3. Switch INV1 DISCONNECT to the ON position.
4. Check inverter display for startup self-test during which LEDs will flash
momentarily. Once self-test is complete, the inverter will display .
(The Fault/Warning LED may flash for a few seconds but eventually will turn
off. If Fault/Warning LED persists, check to make sure a battery temperature
sensor is connected. Also, if the inverter has been pre-configured, it may go
straight into normal operating mode.)
5. Using the Conext System Control Panel, set the First (Master) Inverter Device
Number:
a) Go to the inverter’s Advanced Settings menu by pressing Down
arrow + Enter from the System Status screen and then simultaneously
pressing Enter + Up arrow + Down arrow.
b) Select Multi Unit Config menu.
c) Change Dev Number from 00 to 01. The inverter will now appear as
XW6848-01 in the device list.
d) Press Exit to go back to the System Status screen.
6. Switch INV2 DISCONNECT to the ON position.
7. Check inverter display for startup self-test during which LEDs will flash
momentarily. Once self-test is complete, the inverter will display . (If the
inverter has been pre-configured, it may go straight into normal operating
mode or display F66 warning.)
8. Using the Conext System Control Panel, set the Second (Slave) Invert er
Device Number and Inverter Mode:
a) Select the new inverter, XW6848-00, in the device list.
b) Go to the inverter’s Advanced Settings > Multi-Unit Config
menu.
c) Change Dev Number from 00 to 02 (or the next number that has not
been used). The inverter will now appear as XW6848-02 in the device
list.
d) Change Invtr Mode from SplitPhMaster to SplitPhSlave.
e) Press Exit until you see the System Status screen.
9. Check for faults. If fault condition(s) exist, correct and restart Functional Test.
10. If a third inverter is installed, repeat steps to configure it as a Slave.

Test.
14. Check voltage at AC LOAD terminals of the Master inverter.
15. Switch the AC Load breakers ON.
16. Confirm operation of connected AC loads.
17. Disconnect AC LOAD breakers.
18. Using the Conext System Control Panel, reduce maximum charge rate.
a) From the System Status screen, go to System Settings and
enable Cascading (if not enabled). With Cascading enabled, a
change to a setting in one inverter will automatically ripple through to the
other inverter(s) in the system.
b) Go to Advanced Settings > Charger Settings in one of the
inverters.
c) Set Max Chg Rate to 10%.
d) Press Exit until you see the System Status screen.
19. Switch AC input breakers ON.
Note: All inverters in the system must be connected to the same AC input
source before they will qualify the source.
20. Confirm both inverters start charging.
Note: With Max Chg Rate set to 10% the maximum charge rate is limited to
10 A on each inverter. Depending on the battery bank’s state-of-charge, the
output from one or more inverters may quickly drop to zero. This is
considered normal operation.
21. Check for faults. If fault condition(s) exist, correct, and then restart the
Functional Test.
If the Inverters pass the Functional Test, proceed to the Commissioning
procedure as defined in Conext XW+ Inverter/Charger Owner’s Guide.

Xanbus Network
Installation
Chapter 4, “Xanbus Network Installation”
provides detailed information for planning and
installing the components necessary for network
communication on a Xanbus system.
Topics in this chapter include:
• “The Xanbus Network” on page 4–2
• “Installing the Network” on page 4–4
975-0239-01-01 Rev G
4–1
This manual is for use by qualified personnel only
Xanbus Network Installation
The Xanbus Network
A Xanbus network is a collection of Xanbus enabled devices that perform
individual functions, but also communicate and interact with other devices on the
network. The network capability of the Conext XW+ provides a solution that
simplifies and automates the installation, configuration, control, monitoring, and
integration of devices.
Network Components
NOTICE
SHORT CIRCUIT OF NETWORK COMPONENTS
• This network is not an ethernet system. Only connect Xanbus-enabled
devices to other Xanbus-enabled devices. Do not attempt to connect
Xanbus-enabled devices to other networks or systems.
• Ethernet crossover cables are not compatible with the Xanbus system. Use
Category 5 (CAT 5 or CAT 5e) cables to connect Xanbus-enabled devices.
• Do not install network terminators in an AC Sync port.
Failure to follow these instructions can result in damage to equipment.
A Xanbus network consists of three elements: Xanbus-enabled devices, Xanbus
power supply, and Xanbus cables.
Each device is integrated into the network using cables, network connectors,
and terminators. An example of a network system is shown in Figure 4-1.

The Xanbus Network
Xanbus-enabled devices
A Xanbus-enabled device is any product that works on a Xanbus network. Below
are some examples of Xanbus-enabled devices:
•
Conext System Control Panel
•
Conext XW+ Inverter/Charger
•
Conext Automatic Generator Start
•
Conext Battery Monitor
•
MPPT 60 150 Solar Charge Controller
•
MPPT 80 600 Solar Charge Controller
Due to network traffic, the maximum number of Conext XW+ units in a single
Xanbus network should not exceed twelve. The maximum number of Conext
MPPT Solar Charge Controllers in a single Xanbus network should not exceed
twelve.
The combined maximum number of Conext XW+ units and Conext MPPT Solar
Charge Controllers should not exceed twelve.
Xanbus power supply
Xanbus-enabled devices are either power-supplying or power-consuming. The
Xanbus network needs at least one device with a power supply sufficient to run
the entire network.
Note: The total network current supplied by the power-sourcing devices must be
equal to or greater than the total current drawn by the power-consuming devices.
The power supply must be capable of providing 15 VDC/200 mA to each device.
For example, in a system with an Conext XW+ Inverter/Charger, Conext System
Control Panel, and Conext Automatic Generator Start, the Conext XW+ is a
power-supplying device capable of providing 800 mA at 15 VDC while the two
other devices each consume a maximum of 200 mA for a total maximum
consumption of 400 mA. In this example, the network is properly configured from
a power perspective because the power source is capable of providing more
current than is needed: 800 mA  400 mA.
Note: See the specifications for each Xanbus-enabled device to determine how
much power each device consumes or supplies.
975-0239-01-01 Rev G

This manual is for use by qualified personnel only
Xanbus Network Installation
Xanbus cables
Each Xanbus-enabled device is connected by a Category 5 (CAT 5 or CAT 5e)
cable, a standard cable available from the manufacturer or any computer supply
store. The cable consists of eight conductors in four twisted pairs with an RJ45
modular connector wired to the T568A standard.
Figure 4-2 Xanbus Cable
Network terminators
The Xanbus network must be properly terminated at each end to ensure the
communication signal quality on the network.
Note: 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.
The Conext XW+ Inverter/Charger and other Xanbus-enabled devices ship with
one network terminator. Depending on your network layout, this terminator may
need to be removed from the XW+ Inverter/Charger and inserted into another
device elsewhere in the network.
Figure 4-3 Network terminator
Installing the Network
Note: Installing and replacing Xanbus-enabled devices in an existing system
must be performed with the Conext XW+ Inverter/Charger in standby mode. For
more information about standby mode, see the Conext System Control Panel
Owner’s Guide.

Figure A-1 Conext XW+ AC Overload Capability
Output Power Versus Ambient Temperature
Note: For the Conext XW+ 6848 model, the power can be limited by the
installed DC and AC breakers. For example, at 8500 W the DC or AC breakers
may disconnect before the 30 minute rating.
When the internal temperature of the Conext XW+ exceeds a preset limit, it
begins to limit output power automatically to stop maximum internal temperatures
from being exceeded.
