2 General Safety

This manual supports safe handling of the device. Use the device solely in
accordance with its intended use:

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
prohibited and do not conform to its intended use. Only use original LEAB
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

connect control modules directly to the PowAirBox. Always use an
additional relay for this purpose.

 Reverse polarity can damage the unit: Before operation, make sure

that all cables are connected correctly in accordance with the
connection diagram (see page 13).

3 About 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.

About the PowAirBox User Manual

There are two types of the PowAirBox:

 PowAirBox Type A (supply of electricity and compressed air)
 PowAirBox Type B (supply of electricity)

Both types are available for 12 V, 24 V or 230 V. Due to coding, supplies and
couplings of different voltages are not interchangeable. However, types A
and B are compatible at the same voltage and can be inserted together to
supply a vehicle with electricity. There is no air supply when doing this, but
also no air loss. The supply unit and coupling are supplied with
prefabricated connecting cables. The connection in the vehicle is made via
lockable plug-in connectors.

The PowAirBox System

When installing the PowAirBox system in the vehicle depot, LEAB
recommends direct connection to the electricity and compressed air
distribution with the LEAB PowAirBox ceiling bracket . The combination
cable (electricity and compressed air) leads from the ceiling bracket to the
supply unit installed in the vehicle . LEAB also recommends the use of
LEAB ABC, LEAB CPC or LEAB Champ Pro built-in chargers.

For vehicle depots without a complete PowAirBox system, LEAB also offers
supply adapters with different plug connections (e.g. CEE).
