Configuring the System for Multiple Unit Operation

Verify all DC and AC connections. Check Xanbus network connections and

ensure that terminators are installed at devices at each end of the network. The

simplest system includes a Xanbus SCP, the two multi-unit-configured Conext

SW inverter/chargers, and two Xanbus terminators.

For both units to operate in multiple unit configuration, a Master and Slave have

to be assigned. The default out-of-box configuration for all Conext SW inverter/

chargers is Master which causes a conflict the first time the system is powered

up. The installer will need to change configuration on one of the inverter/chargers

to Slave mode.

To configure the system for multiple unit configuration:

1. Apply DC power to both inverter/chargers.

Power up order has no impact. Because there are now two Master units in

the system, the SCP will detect an F71 fault, a “system configuration fault”.

2. From the SCP System Status screen, press Enter. The Select Device screen

appears.

3. Select the inverter to configure as a Slave unit from the list, then press Enter.

4. Bring up the Advanced Settings screen by pressing Enter, Up, and Down

arrow buttons all together.

5. Select Advanced Settings and press Enter. The Advanced Settings screen

appears.

6. Scroll down to select Multi Unit Config.

At this point all devices in the system will be automatically placed in standby

mode. All three LEDs on the inverter to be configured will start flashing

7. Select Invtr Mode and press Enter.

8. Select Slave and press Enter.

9. Press the Exit button repeatedly until the System Status screen appears.

NOTE: The only situation in which the Slave may shut down the Master inverter

is during fault detection conditions such as high or low battery voltage,

overcurrent, or over-temperature conditions. Both inverters will auto reset after a

fault detection condition has been cleared. The exception is that an overcurrent

condition will generate a shutdown for both inverters that will require a manual

restart of the system.
