the positive lead; always remove the instrument’s
ground lead last.
11. Components that are critical for safety are indicated in the circuit diagram by shading,
or .
12. Use replacement components that have the same
ratings, especially for flame resistance and dielectric strength specications. A replacement part
that does not have the same safety characteristics
as the original might create shock, re or other
hazards.
NOTE: Connect the oven to a 25 A.
When connecting the oven to a 16 A,
make sure that circuit breaker can operate.
13. Never touch any circuit wiring with your hand nor

not apply AC power to the unit (or any of its assemblies) unless all solid-state heat sinks are correctly
installed.
9. Some semiconductor (“solid state”) devices are
easily damaged by static electricity. Such components are called Electrostatically Sensitive Devices
(ESDs). Examples include integrated circuits and
eld-effect transistors. Immediately before handling
any semiconductor components or assemblies,
drain the electrostatic charge from your body by
touching a known earth ground.
