Contacting the Electrician
As mentioned previously, there are some installation tasks that require a certified Electrician.
⚠ DANGER All wiring must be performed by a licensed, certified Electrician.
All installations need an Electrician to:
• Install a Power Disconnect Switch. Ensures you can quickly and completely interrupt
electrical power to the Lift in the event of an electrical circuit fault, emergency situation, or when
equipment is undergoing service or maintenance. Put it within sight and easy reach of 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. The Power Unit that comes with the Lift is
not thermally
protected.
Refer to Install a Thermal Disconnect Switch for more information.
Additionally, if your Lift came with a 220 VAC Power Unit, you will need the Electrician to:
• Connect the
220 VAC Power Unit to an appropriate power source. Have the
Electrician wire the Power Unit either to a 220 VAC Power Cord and Plug or directly to the facility’s
power system.
NOTICE If your Lift came with a 110 VAC Power Unit, it already has a power cord and
appropriate plug. Just plug it in to a 110 VAC outlet.
The Electrician needs to provide the following components for all installations:
• a Power Disconnect Switch
• a Thermal Disconnect Switch
If your Lift came with a 220 VAC Power Unit, the Electrician is also responsible for providing:
• an appropriate Power Cord and Plug if you want to attach the Power Cord to a 220 VAC Plug (and
then plug it in to an appropriate 220 VAC outlet) or just a Power Cord if you want to wire the Power
Unit directly into the facility’s power system.
Refer to Wiring Diagrams for additional wiring information.
