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.

opening in the thermostat adaptor plate.
5. Secure the adaptor plate to the conduit box with
the two machine screws provided.
6. Insert the wires through the opening in the
