EK280
Danger!
For EK280 with internal 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.
− Remove the four screws from the top of the EK280 and open it.
− Unplug the modem from the power supply to avoid damage to the modem and SIM card. This
applies also to an EK280 with power supply which is disconnected from the mains, in case a back-up
battery supply is connected!
Do not connect
anything to this
plug.
