To avoid risk of injury and prevent damage to the hardware:
n
Do not apply voltages/currents outside the specified ranges to the
connector pins.
n
Do not connect or disconnect any devices while the dSPACE
system is powered up and/or external devices are switched on.
Make sure that the expansion box (if used) and external devices
are turned off beforehand.

Safety Precautions for Using Expansion Boxes
To avoid damage to the expansion box and to achieve safe and
trouble-free operation, the following guidelines have to be observed.
Objective
Before doing any installation work on an expansion box:
n
Make sure that the PC is turned off and no external devices are
connected to the box.
n
Unplug all external connectors from all boards already installed,
because these connectors might conduct dangerous high voltage
into the chassis or parts of the circuit.
Installing
n
If there is any chance that external devices connected to the
boards might conduct dangerous high voltage into the chassis,
never unplug the power cord, which is the system’s protective
ground, unless all other connectors are unplugged.
n
The power cord must be plugged into a grounded wall outlet only.
Grounding
n
Before you work with an expansion box, you should always turn
on the expansion box before the host PC.
n
Do not switch off the expansion box while the host PC is still
running. This might lead to unpredictable errors.

The operating temperatures of hardware devices directly affect
their life time and their function. You must therefore ensure that
the ambient temperature of the dSPACE system does not exceed
the specified maximum temperature. For details, refer to
