To reduce the risk of electric shock, your opener is provided with an insulated
power cord with a 3-prong grounding plug. The power cord permits easy
connection to and disconnection from an electrical outlet. The power cord must be
plugged-in to a standard grounded outlet. If there is no outlet available at the
location, you must have a qualified electrician install an approved-grounded outlet
at the proper location.
To help prevent electrocution or fire, etc., the installation and wiring and
outlet must be done in accordance with local electrical and building codes. DO NOT
use an extension cord. DO NOT use a 3-prong to 2-prong plug adapter. DO NOT
modify or cut off the grounding pin on the plug.
