Caution
Do not connect the product to signals or use for measurements
within Measurement Categories III or IV.
Attention
Ne pas connecter le produit à des signaux dans les catégories
de mesure III ou IV et ne pas l'utiliser pour effectuer des mesures dans ces
catégories.
Measurement Category II is for measurements performed on circuits directly
connected to the electrical distribution system. This category refers to local-level
electrical distribution, such as that provided by a standard wall outlet, for example,
115 V for U.S. or 230 V for Europe.
Safety Guidelines for Hazardous Voltages
Caution
Ensure that hazardous voltage wiring is performed only by
qualified personnel adhering to local electrical standards.
Caution
Do not mix hazardous voltage circuits and human-accessible
circuits on the same module.
Caution
Ensure that devices and circuits connected to the module are
properly insulated from human contact.
