Before powering on the device, ensure the power cable is connected correctly, and all water, vent,
purge and hydrogen pipes are properly connected and secured as described in this manual.
Remote Start/Stop
The EL can be started remotely using the Enapter app or cloud, by any user with access and correct
permissions to the site the device was added to. For detailed information on this, please refer to the
The device can also be used and controlled remotely via the Modbus interface. For more information

Manual Start/Stop
When the device is in standby mode,
push the start/stop button
this will start the Electrolyser.
To stop the Electrolyser, simply push the start/stop button. The Electrolyser then ramps down and
purges the contained H2 to return itself to a safe state.
Warning!
Do not unplug/disconnect the power to the EL 2.1 without either manually
or via software control shutting down the device safely. Unexpected power
cuts can shorten the device's lifetime and damage the system!
Maintenance Mode
Maintenance mode can be manually enabled using the Enapter App. This is used to safely fill and drain
the device, as well as to guide you through inspection and other routine maintenance tasks.
Set Production Rate
As previously explained, due to the pressure difference inside the AEM stack there is a hydrogen
crossover that will get out from the vent line. At 100% production rate, the gas output from this line
has a maximum hydrogen concentration of 2%. While at the minimum production rate of 60% the
crossover will be higher, but still remain under the 4% threshold.
Setting the production rate on the Cloud can be done in a very simple way on the main page of the
Electrolyser. On the "Commands" section click on the button "Set Production rate".
