7 Connecting individual QuantumX modules
7.1 Connecting the supply voltage
Connect the modules to a DC voltage of 10 V ... 30 V (24 V typical). The power
consumption per device can be found in the following table.
CAUTION
The following rule of thumb applies to power distribution via FireWire:
“An external voltage supply with the same voltage potential is required on
every 3rd module“.
Defects in the module cannot be excluded if a supply voltage > 30 V is used. If
the supply voltage drops below 10 V, the modules switch off.
We recommend installing an uninterruptible power supply (UPS) in vehicles
with battery operation between battery and module to compensate for voltage
drops during start procedures.
