WARNING: Risk of Electric Shock.

Disconnect or isolate all power supplies before making electrical connections. More than one 
disconnection or isolation may be required to completely de-energize equipment. Contact with 
components carrying hazardous voltage can cause electric shock and may result in severe personal 
injury or death.

AVERTISSEMENT : Risque de décharge électrique.

Débrancher ou isoler toute alimentation avant de réaliser un branchement électrique. Plusieurs 
isolations et débranchements sont peut-être nécessaires pour -couper entièrement l'alimentation de 
l'équipement. Tout contact avec des composants conducteurs de tensions dangereuses risque 
d'entraîner une décharge électrique et de provoquer des blessures graves, voire mortelles.

!

CAUTION: Risk of Property Damage.

Do not apply power to the system before checking all wiring connections. Short circuited or improperly 
connected wires may result in permanent damage to the equipment.

MISE EN GARDE : Risque de dégâts matériels.

Ne pas mettre le système sous tension avant d'avoir vérifié tous les raccords de câblage. Des fils 
formant un court-circuit ou connectés de façon incorrecte risquent d'endommager irrémédiablement 
l'équipement.

!

CAUTION: Risk of Property Damage.

Insulate and secure each unused wire lead before applying power to the actuator. Failure to insulate 
and secure each unused wire lead may result in property damage.

MISE EN GARDE : Risque de dégâts matériels.

Isoler et protéger chaque fil non utilisé avant de mettre l'actuator sous tension. Le non-respect de cette 
obligation d'isolation et de protection de chaque fil non utilisé risque d'entraîner des dégâts matériels.

IMPORTANT:

Make all wiring connections in accordance with the National Electrical Code and local 

regulations. Use proper Electrostatic Discharge (ESD) precautions during installation and servicing to avoid 
damaging the actuator’s electronic circuits.
