Activating the HMI

In general, you do not have to activate the HMI. In normal operation, the HMI and its display are always on:

  • When the Trailer Refrigeration Unit (TRU) is on,

  • or when the ignition is on or the truck is on the road,

  • or when the Energ-e Pack is connected to shore power and the HV battery is being charged.

  • The HMI is also on when Axle Power is in Standby Mode.

There is no time out for the HMI display, for example if you do not use it for some minutes.


If the HMI is off and the display is ‘black’, you can activate the HMI:

  • Short press the ON/OFF button for 1-2 seconds. This ‘wakes up’ the system, starting the HMI at the same time.

Of course, you can also turn on ignition or the TRU or connect the Energ-e Pack with shore power. This also ‘wakes up’ the system and with it the HMI.


Note that information needs a few seconds until it is completely shown on the display.
