Risk of Electric Shock
•
•
The direct connection to the AC power line and the open and unprotected boards present a serious risk of electric
shock and can cause serious injury or death. Extreme caution needs to be exercised while handling this board.
Avoid contact with the exposed conductor or terminals of components on the board. High voltage is present on
exposed conductor and it may be present on terminals of any components directly or indirectly connected to the AC
line.
•
•
•
Dangerous voltages and/or currents may be internally generated and accessible at various points across the board.
Charged capacitors store high voltage, even after the circuit has been disconnected from the AC line.
Make sure that the power source is off before wiring any connection. Make sure that all connectors are well
connected before the power source is on.
•
Follow all laboratory safety procedures established by your employer and relevant safety regulations and guidelines,
such as the ones listed under, OSHA General Industry Regulations - Subpart S and NFPA 70E.
Suitable eye protection must be worn when working with or around demonstration boards. Always
comply with your employer’s policies regarding the use of personal protective equipment.
All components, heat sinks or metallic parts may be extremely hot to touch when electrically active.
Heatsinking is required for Q4 & Q5. The end product should use tar pitch or an equivalent compound for
