1.5.1 Design Guidelines
Note the following requirements for incorporating a BL2100 series single-board computer
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 BL2100 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 BL2100, it is the responsibility of the end-user to use
proper ESD precautions to prevent ESD damage to the BL2100.
Safety
•
All inputs and outputs to and from the BL2100 single-board computer must not be con-
nected to voltages exceeding SELV levels (42.4 V AC peak, or 60 V DC).
•
The lithium backup battery circuit on the BL2100 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.
1.5.2 Interfacing the BL2100 to Other Devices
There are two versions of the LCD/keypad module that may be used with the BL2100: a
plug-in version (Part No. 101-0465), and a remote panel-mounted version with bezel (Part
No. 101-0502). The BL2100 with the LCD/keypad module plugged in may be regarded as
a “maintenance unit” that conforms to the same CE standards as does the BL2100 alone,
where the entire assembly is mounted inside an enclosure, and the enclosure is only
opened to “tune up” the system. In addition, the cable for a panel-mounted LCD/keypad
module should be less than 30 cm (12") to maintain CE compliance. Appendix C provides
complete information for mounting and using the LCD/keypad module.
Since the BL2100 single-board computers are designed to be connected to other devices,
good EMC practices should be followed to ensure compliance. CE compliance is ulti-
mately the responsibility of the integrator. Additional information, tips, and technical
assistance are available from your authorized Rabbit distributor, and are also available on
