4�10�3�5� Power status�

TAll the Modbus map addresses are hexadecimal.

The 0x04 function is implemented for this variable.

This variable indicates the quadrant in which the unit is operating.

4�10�3�6� Unit conguration variables.

All the Modbus map addresses are hexadecimal.

The 0x04 and 0x10 functions are implemented for this variable.

The unit’s Modbus function does not check whether the variables recorded are within the

correct margins, they are only checked when they are read from the EEPROM. So if any

parameter is recorded with an incorrect value the unit will be congured with its default value.

The Modbus conguration will not take effect until the unit is reset.
