CAUTION
Modules which are sensitive to electrostatic charge may be destroyed by voltages
which are far below the human level of perception. These voltages occur already
when you touch a component or electrical connections of a module without first dis-
charging yourself electrostatically. The damage incurred by a module as a result of
an overvoltage is not usually immediately perceptible but only becomes noticeable
after a long time in operation.
