6 Wildcat (BL2000)
1.4.1 Design Guidelines
Note the following requirements for incorporating the BL2000 series of single-board com-
puters into your application to comply with CE requirements.
General
•
The power supply provided with the Tool Kit is for development purposes only. It is the
customer’s responsibility to provide a CE-compliant power supply for the end-product
application.
•
When connecting the BL2000 single-board computer to outdoor cables, the customer is
responsible for providing CE-approved surge/lighting protection.
•
Rabbit recommends placing digital I/O or analog cables that are 3 m or longer in a
metal conduit to assist in maintaining CE compliance and to conform to good cable
design practices.
•
When installing or servicing the BL2000, it is the responsibility of the end-user to use
proper ESD precautions to prevent ESD damage to the BL2000.
Safety
•
All inputs and outputs to and from the BL2000 series of single-board computers must
not be connected to voltages exceeding SELV levels (42.4 V AC peak, or 60 V DC).
•
The lithium backup battery circuit on the BL2000 single-board computer has been
designed to protect the battery from hazardous conditions such as reverse charging and
excessive current flows. Do not disable the safety features of the design.
1.4.2 Interfacing the BL2000 to Other Devices
Since the BL2000 series of single-board computers is designed to be connected to other
devices, good EMC practices should be followed to ensure compliance. CE compliance is
ultimately the responsibility of the integrator. Additional information, tips, and technical
assistance are available from your authorized Rabbit distributor, and are also available on
