Foreword
Precautions
Because this product is an open device, it must be installed in a dustproof, moisture-resistant,
shock/impact-resistant case before use. Protective measures (such as only special tools or a
key can open the case) should be used to prevent operation by non-maintenance personnel or
accidental impacts, which may cause risk and damage.
Note: Please comply with the precautions in this user guide. If failure to comply with these
precautions and guidelines cause the controller or peripheral products to malfunction, this may
lead to such severe consequences as fire or shocks and even injury or death.
Note: Shock hazard! To avoid electric shocks, after the device has been powered up, please do
not touch the AC power terminals. When checking the input power, make sure that power is off.
To avoid personal injury and damage to other equipment, because this product is an open
device, please avoid using in hazardous application situations. Please install this device on
equipment with fail safe protective devices.
This device is not equipped with a power switch or fuses. This products application system
should therefore have a switch or circuit-breaker, and the switch or circuit-breaker must be in
locations easily accessible to operators and have clearly visible on-off markings.
To avoid the danger caused, in the same expansion cassette or I/O expansion module, when a
channel is connected to high voltage, other channels cannot be connected to a safe low voltage
circuit.
Précautions
Comme ce produit est un appareil ouvert, il doit être installé dans un boîtier étanche à la
poussière, à lhumidité et aux chocs / chocs avant utilisation. Des mesures de protection (telles
que seuls des outils spéciaux ou une clé peuvent ouvrir le boîtier) doivent être utilisées pour
empêcher le fonctionnement par du personnel non chargé de la maintenance ou des chocs
accidentels, qui peuvent entraîner des risques et des dommages.
Remarque: veuillez respecter les précautions de ce guide de lutilisateur. Si le non -respect de
ces précautions et directives entraîne un dysfonctionnement du contrôleur ou des produits
périphériques, cela peut entraîner des conséquences graves comme un incendie ou des chocs
et même des blessures ou la mort.
Remarque: risque délectrocution! Pour éviter les chocs électriques, une fois que lappareil a été
mis sous tension, veuillez ne pas toucher les bornes dalimentation CA. Lors de la vérification
de la puissance dentrée, assurez -vous que lalimentation est coupée.
Pour éviter des blessures corporelles et des dommages à dautres équipements, car ce produit
est un appareil ouvert, veuillez éviter de lutiliser dans des situations dapplication dange reuses.
Veuillez installer cet appareil sur un équipement doté de dispositifs de protection à sécurité
intégrée.
Cet appareil nest pas équipé dun interrupteur dalimentation ou de fusibles. Le système
