US standards

Continuous sound pressure level at ear level:
NOTICE The continuous sound pressure level is a value determined in accordance
with the standard, taking into account the sound pressure level while driving,
lifting and at idle. The sound pressure level is measured at ear level.
Vibrations: 1.97 ft/s
NOTICE The vibration acceleration acting on the body in the operating position is the
linearly integrated, weighted acceleration in the vertical direction. It is
determined via shock waves when driving at a constant speed.
Electromagnetic compatibility (EMC)
The manufacturer confirms compliance with the limit values for electromagnetic
interference, interference resistance and electrostatic discharge testing as set out in
the table below:
Interference resistance
The following limit values apply for industrial trucks/transportation systems:
Environmental phenomenon
1.1
Electromagnetic field
Amplitude modulation
1.2
Electromagnetic field
1.3
* The frequency range was expanded to include the low-frequency
interference in the wiring.
NOTICE Very strong electromagnetic fields can adversely affect the performance of
the industrial truck. In the same way, machinery that is highly sensitive to
electromagnetic fields may also be adversely affected by the industrial truck.
Be sure that emitted interference from the industrial truck cannot interfere
with the operation of adjacent machinery.
NOTICE Electrical or electronic components and their configuration may not be
modified without the prior written approval of the manufacturer.
