Introduction and Setup
1.4 Warnings
The SMOS EVM motor board kit includes a rotating machine and power
transistors. Both can reach temperatures hot enough to cause burns! To
facilitate safe operation, 12-volt input power should come from a dc
laboratory power supply that is current limited to no more than 10 amps.
The user should be aware that:
• Before moving scope probes, making connections, etc., it is
generally advisable to power down the 12-volt supply.
• Standalone operation of the board should be allowed only with use
of an insulative pad or standoffs as shown in Figure 1-3 .
• Wearing safety glasses, avoiding neckties and jewelry, using
shields, and operation by personnel trained in power electronics
lab techniques are also advisable.
