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. They are designed to interrupt

electrical power in the event of an electrical circuit fault,

emergency situation, or when equipment is undergoing
service or maintenance.
BendPak strongly recommends that 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 licensed, certified Electrician install
the Power Disconnect Switch.
Make sure the Electrician selects a UL-listed Power

Disconnect Switch.

Installing a Thermal Disconnect Switch

⚠

WARNING

The Lift’s motor does

not

have thermal overload protection.

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 electrical running current that exceeds the motor’s full load amperage rating (FLA) may result in

permanent damage to the motor.
BendPak strongly recommends you

not

exceed the rated duty cycle of the Lift’s motor.
