Benshaw retains the right to change specifications and illustrations in text without prior notification. The contents of this document may
not be copied without the explicit permission of Benshaw.

Do not attempt to install, operate, maintain or inspect the drive until you have thoroughly read this
manual and related documents carefully and can use the equipment correctly.
Do not use the drive until you have a full knowledge of the equipment, safety procedures and instruc-
tions. This instruction manual classies safety instruction levels under “WARNING” and “CAUTION”.
Electrical Hazard that could result in injury or death.
Caution that could result in damage to the drive.
Highlight marking an important point in the documentation.
Please follow the instructions of both safety levels as they are important to personal safety.
High Voltage
Motor control equipment and electronic controllers are connected to hazardous line voltages. When
servicing drives and electronic controllers, there may be exposed components with housings or
protrusions at or above line potential. Extreme care should be taken to protect against shock.
Stand on an insulating pad and make it a habit to use only one hand when checking components. Always
work with another person in case an emergency occurs. Disconnect power before checking controllers
or performing maintenance. Be sure equipment is properly grounded. Wear safety glasses whenever
working on electronic controllers or rotating machinery.
Congratulations on the purchase of your new Benshaw RSi S4 Sensorless Vector Drive (SVD). The RSi S4
Sensorless Vector Drive is a solid-state AC drive that features Vector Control Algorithm, True Torque Control This
manual gives handling information and precautions for use of this equipment.
Incorrect handling of the drive may result with an unexpected fault or damage to the drive. For best results on
operating the RSi S4 drive, carefully read this manual and all warning labels attached to the drive before installation
and operation. Keep this manual on hand for reference.

SAFETY PRECAUTIONS
SAFETY PRECAUTIONS
Electric Shock Prevention
While power is on or drive is running, do not open the front cover. The capacitor bank may remain charged•
even when power is not applied, and you may get an electrical shock.
This drive contains high voltage which can cause electric shock resulting in personal injury or loss of life.•
Be sure all AC power is removed from the inverter before servicing.•
Wait at least 5 minutes after turning off the AC power for the bus capacitors to discharge. Measure the DC•
Bus voltage between B+ and B- terminals, and ensure DC voltage is below 30V before proceeding.
Do not connect or disconnect the wires to or from drive when power is applied.•
Make sure ground connection is in place.•
Always install the drive before wiring. Otherwise, you may get an electrical shock or be injured.•
Operate the switches with dry hands to help prevent an electrical shock.•
Risk of Electric Shock - More than one disconnect switch may be required to de-energize the equipment•
before servicing.
Injury Prevention
Service only by qualied personnel.•
Make sure power-up restart is off to prevent any unexpected operation of the motor.•
Make certain proper shield installation is in place.•
Apply only the voltage that is specied in this manual to the terminals to prevent damage.•
Fire Prevention
If the drive is faulty, switch off the drive power. A continuous ow of large current could cause a re.•
Mount the drive on a non-ammable surface. Installing the drive directly on or near a ammable surface•
could lead to a re.
Do not connect a resistor directly to the DC terminals. This could cause a re.•
Transportation and Installation
Use proper lifting gear when carrying products, to prevent injury.•
Make certain that the installation position and materials can withstand the weight of the drive. Refer to the•
installation information in this manual for correct installation.
If parts are missing or drive is damaged, do not operate the drive.•
Do not hold the drive by the front cover as it may fall off.•
Do not stand or rest heavy objects on the drive, as damage to the drive may result.•
Do not subject the drive to impact or dropping.•
Make certain to prevent screws, wire fragments, conductive bodies, oil or other ammable substances from•
entering the drive.
Trial Run
Check all parameters, and ensure that the application will not be damaged by a sudden start-up.•
Emergency Stop
To prevent the machine and equipment from hazardous conditions if the drive fails, provide a safety backup•
such as an emergency brake.
Disposing of the Drive
Never dispose of electrical components via incineration. Contact your state environmental agency for•
details on disposal of electrical components and packaging in your area.

PRODUCT OVERVIEW
1 - INTRODUCTION
1.3 Product Overview
Although the S4 AC drive is small in size, it is big on performance. It is an economical yet powerful
solution for many industrial applications. It features remote communications capability (using Modbus
protocol), a keypad for easy conguration, and standard NEMA 4X enclosures that eliminate the need for
mounting in a separate enclosure. The S4 product family includes a wide variety of models to suit almost
any input voltage requirement. An ‘x’ in the following table indicates what models are currently available.
