Do not carry out any modifications, alterations, etc. to the device without the manufactur-
er's consent.
Components that are not in perfect condition must be replaced immediately.
Protecting your-
self and others
Keep unauthorised persons, especially children, away from the device and the vehicle con-
taining the device during operation. If, however, there are people in the vicinity,
-
make them aware of all dangers associated with use of the device (possible risk of suf-
focation due to lack of oxygen in the air, danger from output current, etc.)
-
adhere to the permitted operating conditions as specified in the "Operating conditions"
section of the "Operation" chapter
Before leaving the vehicle in which the device is installed, make sure that no injury or dam-
age can occur in your absence.
Danger from gas-
es, hazardous
materials and suf-
focation
The fuel is supplied in the form of gaseous hydrogen. Hydrogen is a dangerous substance,
which requires great care when handling. Further information on handling hydrogen can
be found in the safety data sheet of the hydrogen supplier.
Only use the device in well-ventilated areas to prevent the accumulation of explosive gas.
Spaces are not deemed to be at risk of explosion if a concentration of hydrogen of less than
4% by volume can be adequately guaranteed by the use of natural or forced ventilation.
Keep possible ignition sources, fires and naked flames away from the device, also inflam-
mable materials, liquids and gases.
Using the device in spaces with inadequate ventilation can cause suffocation with no visi-
ble or otherwise detectable warning. This is because of the oxygen consumption of the de-
vice, which can lead to a lack of oxygen in the room if it is inadequately ventilated. The
device must only be operated in rooms with a volume of not less than 10 m³ and with an
air circulation rate of not less than 0.6/h. Example: With a room volume of 10 m³, an air
circulation rate of 0.6/h means that 6 m³ of air are renewed per hour. Other spatial condi-
tions require an exact calculation of the air circulation rate in consultation with the device
manufacturer.
Safety measures
in normal opera-
tion
Only operate the device if all of its protection devices are fully functional. If the protection
devices are not in full working order, there is a risk of
-
injury or death to the operator or a third party
-
damage to the device and other material assets belonging to the operator
-
inefficient operation of the device
Any safety devices that are not functioning properly must be repaired before switching on
the device.
Never bypass or disable protection devices.
Before switching on the device, ensure that no one is likely to be endangered.
Observe the commissioning and operating requirements as set out in the "Before commis-
sioning" and "Commissioning" chapters.
