- MasterBus: connect two MasterBus cables (or one cable and one Terminator). See
- CZone: connect the drop cable. On the battery side, plug the connectors into either
of the communication ports. See Figure 6 on page 12.
Step 8. Press the Battery switch-button for 5 seconds to switch the battery on. LED C will be solid on for
1 minute to indicate that the switch is closed.
Step 9. Switch on some loads and verify that they are working. Switch off the load, switch on the
charger and verify (charger status) that the battery is being charged.
To change the default settings according to your needs, either use the DIP switches or a configuration
tool. For optimal use, it is strongly recommended to configure a
Stop charge
event. See page 18 for
more information.
Adding the MLI Ultra to a MasterBus network
MasterBus is a CAN based, fully decentralized data network for communication between Mastervolt
devices. MasterBus is used as power management system for all connected equipment, such as the
inverter, battery charger, generator and many more. Every device that is compatible with MasterBus is
equipped with two data ports. The devices are simply daisy chained together, forming a local data
network
1. Disconnect a MasterBus cable or Terminator from the closest MasterBus device and connect it to
the MLI Ultra.
2. Connect the new MasterBus cable to the other MasterBus device and then connect to the MLI Ultra.
3. Ensure that the network is properly terminated.

Adding the MLI Ultra to a CZone network
The CZone network is an NMEA 2000-compliant CAN-based system. In a CZone network, the MLI
Ultra can be monitored from a remote panel like the Touch 5. The settings can only be adjusted with the
CZone Configuration Tool.
Additional required materials per MLI Ultra:
1. Disconnect the backbone at the closest backbone connection and add in a tee connector (not
included).
2. Reconnect the backbone connection(s) with the new tee connector in place. Ensure that the network
is properly terminated.
