VERIFICATION OF INSTALLATION
ATTENTION Use only tools and equipment with non-conducting handles when working on
electrical devices.
After switching on the power supply the red LED should be on to indicate that the unit
is supplied. The green LED indicates that the output is active. If this is not the case,
check the connections.

INPUT REGISTERS ( see Table Input registers below )
The input registers are read-only. All data can be read using the “Read Input Registers”
command.
Table Input registers shows the returned data type and the way it should
be interpreted.
HOLDING REGISTERS ( see Table Holding registers below )
These registers are read / write registers and they can be managed via “Read Holding
Registers”, “Write Single Register” and “Write Multiple Registers” commands. The
registers that are not used are read-only and, therefore, writing in these registers
neither returns a Modbus error exception, nor makes any changes.
