The LEAB PowAirBox is a system for supplying electricity and compressed
air to emergency vehicles.
Assembly and installation should only be carried out by qualified
electricians. Any modifications to the device or its components are

or LEAB-approved accessories.
When installing and using the PowAirBox, observe the basic safety
instructions:
Electric current hazard: Before operation, make sure there are no
open or damaged cables.
Replace defective parts or damaged cables immediately.
Only use the PowAirBox within the specified voltage limits.
Device defect and faulty ejection due to control modules: Do not

3About the PowAirBox
With the LEAB PowAirBox, the supply is fed in via a special plug connection
and combines electricity and compressed air in a single cable. When the
vehicle engine is started, the coupling is automatically disconnected from
the vehicle and the protective cover closes automatically. The status display
provides reliable information about the current charge status of the
connected battery and the charging process. Two auxiliary contacts
installed in the PowAirBox serve to establish a start locking mechanism.
