7 Connecting individual QuantumX modules
7.1 Connecting the supply voltage
Connect the modules to a DC voltage of 10 V ... 30 V
(24V recommended). 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 poten
tial 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.
