The Electrician needs to:

the Lift operator. Refer to Install a Power Disconnect Switch for more information.
• Install a Thermal Disconnect Switch. Ensures the equipment shuts down in the event of an
overload or an overheated motor. Refer to Install a Thermal Disconnect Switch for more
information. Note that the Power Unit that comes with the Lift is
not thermally protected.
The electrician is responsible for providing:
• an appropriate cable and plug to attach to the Power Unit, for connection to a wall outlet
or an
appropriate cable that attaches the Power Unit to the facility’s electrical system
