INSTALLATION STEPS – Elster® AS3000, AS3500

• Step #1: Take off the meter’s communication module plastic case by releasing the screw from the top middle part of the housing.
• Step #2: Now snap the modem unit PCB into the communication module’s plastic housing by sliding it through the guiding rails of the case until you hear a click sound. Beware to place the modem unit PCB to the slot nearer the screw. The 12 pins communication interface connector (3) must be in the right angle and direction, closer to the SMA antenna connector (6) (right top side on the picture).
• Step #3: The PCB must be pushed until it is locked and fixed into the communication module’s case. At the middle of the modem unit PCB there is whole that permits to the fixation hook of the communication module’s housing to fix and holds back the modem unit PCB. When you want to remove the modem unit PCB, you must force the hook to release the PCB.

  

• Step #4: Now we can connect the communication module to the meter by sliding the communication unit into the meter housing.
• Step #5: The communication interface (3) and the mains connectors (1) must be connected to the connector pairs from the meter housing.

INSTALLATION STEPS – Elster® AS220, AS230

• Step #1: Disassemble the meter’s communication module plastic case. Release the top screw at the middle and take off the cover from the modem (at top).
• Step #2: The modem PCB can be inserted into the transparent plastic housing of the communication modem.
• Step #3: Inside the communication module’s transparent plastic case, mount the SMA-M antenna connector on the housing (fasten by connector’s screw).
• Step #4: The communication modem is ready to be attached to the meter by attaching to the meter housing. The 12 pins communication interface (3) and the mains connector (1) now plugs into the meter.
  

INSTALLATION STEPS – Elster® AS1440

• Step #1: Connect the external PCB adapter with the 12 pins ribbon cable and slide the connector to the 12-pins
  communication interface (3) of the modem PCB. The wire marked with red must be positioned towards the edge of the modem PCB. The communication / power of the electricity meter is provided by the 6-pin Elster® -customized interface connection adapter.
• Step #2: Take off the meter’s terminal cover that hosts the communication module’s plastic housing and release the back cover of the module to place the modem to the terminal cover.
• Step #3: Mount the SMA-M antenna connector on the back cover of the modem . Fasten with the antenna connector’s screw.
• Step #4: Insert the modem PCB inside the terminal cover’s communication module housing by sliding it through the guiding rails that are closer to the fastening screws. Take care to position pf the PCB amd the power supply module (10) – it must be on the right-side – as it is shown on the picture. The 12-pins connector and its wire must be oriented to the left side.
• Step #5: The modem PCB must be pushed, until it will be locked and fixed into the case. In the terminal cover are fastening points to hold the PCB in the cover.
• Step #6: Place the external power supply adapter PCB into the terminal cover case at the proper direction as it can be seen in the picture. The 6-pins Microfit connector must be oriented to upside, the 12-pins wire must be placed to the left side. Please mind to arrange the ribbon cable to not obstruct the cover to be fixed on top of the modem housing!
• Step #7: Now place back modem’s cover and fasten by locking tabs and the screw. Insert the modem unit tot he electricity meter. The 6-pins connector will provide power and data connection from the meter to the module.
  

TURN ON THE DEVICE

After assembling the modem, turn on the meter. The modem begins its operation.
The LED signals will notify about the current operation, status.
