This guide provides you with the basic information required to start up your SMC Flex controller. When reading
this document, look for this symbol “Step x” to guide you through the four basic steps required to install, start-up,
and program the SMC Flex.
The information provided in this Qu
downloaded by visiting www.ab.com. The Quick Start guide assumes the installer is a qualified person with
previous experience and basic understanding of electrical terminology, configuration procedures, required
equipment, and safety precautions.
For safety of maintenance personnel as well as other
maintenance activities, follow all local safety related work practices (for example, the NFPA 70E, Part II in the
United States). Maintenance personnel must be trained in the safety p ra ctices, procedures, and requirements that
pertain to their respective job assignments.
For detailed SMC Flex information including set-up, programming, precautions, and a

WARNING
Step 1 - Read the General Precautions
•Only personnel familiar with the controller and associated machinery should plan or implement the
installation, start-up, and subsequent maintenance of the system. Failure to do this may result in personal injury
and/or equipment damage.
•Hazardous voltage is present in the motor circuit ev
hazard, disconnect main power before working on the controller , motor, and control devices such as Start-Stop
push buttons. Procedures that require parts of the equipment to be energized during troubleshooting, testing,
etc., must be performed by properly qualified personnel, using appropriate local safety work practices and
precautionary measures.
•Failure of solid state power switching components can cause
motor. To prevent injury or equipment damage, the use of an isolation contactor or shunt trip type circuit
breaker on the line side of the SMC is recommended. This device should be capable of interrupting the motor’s
lock rotor current.
•Hazardous voltages that can cause shock, burn, or death
Power terminal covers for units rated 108…480 A can be installed to prevent inadvertent contact with
terminals. Disconnect the main power before servicing the motor controller, motor, or associated wiring.

NOTICE
•The controller contains ESD- (electrostatic discharge) sensitive parts and assemblies. Static control precautions
are required when installing, testing, servicing, or repairing the assembly. Component damage may result if
ESD control procedures are not followed. If you are not familiar with static control procedures, refer to
applicable ESD protection handbooks.

•Stopping modes are not intended to be u
as an emergency stop. The user is responsible for determining
which stopping mode is best suited to the application. Refer to the applicable standards for emergency stop
requirements.
•Pump Stopping may cause motor heating depending on the me

Therefore, select the lowest stopping time setting that will satisfactorily stop the pump.

application errors such as under sizing the motor, over sizing the controller , incorrect or inadequate A C supply,
excessive ambient temperatures, or power quality may result in malfunction of the system.
•The Motor Overload parameter must be

Power Up and Status Display
Note:
•Depending on the SMC option, additional
parameters may appear in some menus
•The external HIM has similar programming
operation to the built-in HIM, however some
differences do exist.
•The built-in HIM can not be used to program
other DPI devices (i.e. Device Select)
Step 3 - Basic Programming
The SMC-Flex controller can be programmed with the built-in keypad and LCD display or with an optional
Bulletin 20-HIM-xx LCD human interface module.
