CAUTION! Electrostatic discharge (ESD). The modules' signal inputs are sensitive to electrostatic
discharge. Take measures to protect against ESD before inserting the module and wiring the inputs.
Note: Strip the insulation from the wires using a suitable tool to prevent damage. Only use cables that
are rated for use at 75°C / 167°F or higher.
