ATTENTION
Wrong connection may cause damage to the device.
u
Observe the safety instructions.
ATTENTION
The short-circuit / reverse polarity protection of the device applies to the operating voltage
connections. A short circuit between operating voltage VBB
X
and USB / Audio / Video might
cause damage to the device.
u
Lay supply and signal cables away from the device using the shortest possible route.
u
Provide all outgoing cables with a strain relief 200 mm behind the cable entry.
Maximum cable lengths:
•
USB ≤ 1.8 m
•
Ethernet ≤ 30 m
•
Video ≤ 30 m
•
Audio ≤ 30 m
Minimum operating quality Audio / Video:
There might be interference to audio/video circuits in the vicinity of strong HF sources or due to ESD.
This may result in audible and visible distortion.
5.5 Operating voltage and circuit breakers
u
The individual electric circuits must be protected in order to protect the whole system.
Automotive spade-type fuses are recommended.
