6.1.4 Replacing the antenna

Danger!
For EK280 with integrated power supply, the mains voltage must be switched off before
opening the housing, ensure it is not turned back on and verify that there is no voltage.
If reception via the integrated modem is too poor, it is possible to replace the mounted short antenna with
SMA connection. To do this, Elster GmbH offers various antennas of varying lengths.
6.1.4.1 Steps
• Remove the cover strip from the housing.
• Loosen the housing screws and open the housing cover.
• Pull the antenna connector on the modem
gently upwards.
• Open the cable gland of the short antenna.
• Remove the short
housing. Be careful not to stretch the
antenna adapter cable when opening the
housing cover.
• Unscrew the short antenna from the
antenna adapter cable.
• Slide the cable gland nut over the external
antenna cable. Then feed the cable into
the housing via the cable gland.
