Installation by a qualified electrician only

All persons involved in the commissioning, maintenance and servicing of the device must be suitably qualified, have experience in working with electrical installations, and read these operating instructions in full and follow them exactly.
The installation information in these operating instructions is intended for qualified specialist personnel only.
Under no circumstances should you attempt to repair the device yourself!
An electric shock can be fatal!
The circuit board must not be used without its housing.

Installation location

The device is designed for installation in an electrical
distribution board with a DIN rail. The device is neither dust-
nor moisture-proof. The distribution board should
therefore have the protection class required
by local regulations.

Power supply

Power is supplied via an integrated
power supply unit connected to the 230V~ mains.
The voltage range is 110-240V~

Connection and wiring
Connection diagrams of the e.station

Figure 2: Connection diagrams of the e.station

Figure 2 shows the connection diagram of the e.station. The digital inputs operate at a voltage of 5-24V.
The integrated 5V output can be used to supply the S0 interfaces of electricity meters, gas meters or water meters. For long cable runs between the meters and the e.station, we recommend an external 12V or 24V power supply unit.
To do this, connect the positive terminal of the 5V supply or of the external power supply unit to one pole of the S0 interface. Connect the other pole to the plus input of the e.station. The minus input of the e.station goes to the negative terminal of the power supply. 
If you have several meters, bridge the corresponding power supply wires.

Once the wiring is complete, you can continue with the network setup: https://enerserve.eu/hilfe-service/e-station/e-station-netzwerkinstallation/
