Modbus RTU (RS485/RS232)
An interface converter is required to be able to connect the Energy Meter D370 to the PCs RS232 interface
andtobeabletocongureitandreaditwithecoExplorergo.
• The Energy Meter D370 has an RS485 interface.
• An interface converter from RS485 (Energy Meter D370) to RS232 (PC) is required.
• Adapt the PCs RS232 interface (e.g. COM1) to be used as the interface.
• The interface converter is also connected to this interface (e.g. COM1).
• Baudrate;IsthespeedatwhichthedataistobetransmittedbetweenthePC,theinterfaceconverter
and the Energy Meter D370.
• Because more than one Energy Meter D370 can be connected to the interface converter, the device ad-
dress set in the Energy Meter D370 must also be set under the connection settings.
• If no connection could be established to the Energy Meter D370, an attempt will be repeated following
the set Timeout.
• When attempting to read data from the Energy Meter D370, the number of attempted connections will be
limited by the number set under Max. no. of attempts.
• When measuring online, the ecoExplorer go will repeatedly attempt to establish a connection to the En-
ergy Meter D370.
4.1.3 Conguration
4.1.3.1 Identity
• The name is used, among other things, to identify the device in the device list.
• Additional information can be saved under Description.
4.1.3.2 Transformer
Voltage transformers
• The voltage measurement inputs are designed for the measurement of low voltages in which rated volt-
ages (L-N/PE) of up to 300 V against earth can occur.
• Voltage transformers are necessary in networks with higher rated voltages.
• Outer voltage L-L must be input for the primary voltage.
• Set the transformer requirements for the current measurement inputs.
Current transformers
• Currents up to 5 A can be measured directly. Observe the installation guide when doing this.
• Transformers are used when measuring currents greater than 5 A.
• Set the transformer requirements for the current measurement input.
