For operation with DC voltages > 32 V, set up a power cable with
adequate cable and fuse ratings. For further information, refer to
dSPACE support.
n The remote voltage should not exceed the supply
voltage. Overvoltage protection of the remote pin is
100 V.
n The remote voltage may be used for starting
AutoBox/Tandem-AutoBox with a remote switch: KL15,
for example (output of the ignition/driving switch).
n If you connect the remote pin to the car battery directly,
the AutoBox/Tandem-AutoBox will always be turned on,
and the car battery will soon be exhausted if the engine
is not running. Thus, a switch is highly recommended.
A preconfigured cable for the supply voltage is provided by dSPACE.
This cable is intended to operate the AutoBox/Tandem-AutoBox with
a laboratory power supply during development. Therefore, pin 4
(remote) is shorted to pin A2 inside the connector in order to save a
separate switch.
Do not use this cable in the vehicle. Otherwise, the
AutoBox/Tandem-AutoBox will always be turned on.
As of March 2009, the VBAT wire (red) contains a melting fuse. The
red wire has a cross-section of 10 mm², the black wire of 6 mm².
Depending on the AutoBox/Tandem-AutoBox version, the melting
fuse has the following characteristics:
n AutoBox:
n Up to Version 3.0: 60 A/32 V, time lag
n Version 4.0 and later: 25 A/32 V, time lag (label on the cable:
CB402AB)
n Tandem-AutoBox
n Up to Version 4.0: 60 A/32 V, time lag
N O T I C E
To avoid damage, do not use a cable with cross-sections
less than 6 mm².
