CONFIGURATION
4 Configuration
All user configurable items are controlled by two groups of switches and a setup program to
modify additional configuration parameters. After changes have been made, the charger
must have both the AC and DC circuit breakers turned OFF then back ON again for any
changes to take affect.
S1 is used to configure the communications interface. S2 is used to set the device address for
Modbus. Setting S1-1 to enable the Setup Program, allows modification to additional
configuration parameters.
