Installing a Power Disconnect Switch
⚠
WARNING A main Power Disconnect Switch is
not provided with this equipment.
A Power Disconnect Switch is a National Electrical Code
(NEC) requirement. It is designed to interrupt electrical
power in the event of an electrical circuit fault,
emergency situation, or when equipment is undergoing
service or maintenance.
We strongly recommend you install a Power Disconnect
Switch that is properly rated for the incoming power.
⚠ DANGER All wiring must be performed by a
licensed, certified Electrician.
Your Power Disconnect Switch must be readily
accessible and installed so that it is in easy reach of the
Lift operator. It must be clearly and legibly marked to
indicate its purpose.
The drawing to the right shows a toggle Power
Disconnect Switch between the Lift’s power source and
its Power Unit. A quick flip of the switch immediately
cuts power to the Lift.
Make sure to have a certified Electrician install the Power
Disconnect Switch.
Make sure the Electrician selects a UL-listed Power
Disconnect Switch.
Installing a Thermal Disconnect Switch

Connect a motor Thermal Disconnect Switch or overload device that will make sure the equipment
shuts down in the event of an overload or an overheated motor.
⚠ DANGER All wiring must be performed by a licensed, certified Electrician.
High running amps that exceed the motor’s full load amps (FLA) rating may result in permanent
damage to the motor.
We strongly recommend you
not exceed the rated duty cycle of the Lift’s motor.
