IMPORTANT

DANGER!

The installation of this product must be done by qualified people,informed about electric hazards (electrocution risks linked to thevoltage levels in the circuit).

Any intervention on the installation must be operated the circuitdisconnected from the electric grid by an electromechanical meaninsuring a sufficient galvanic isolation.

The device concerned by this document is composed of siliconbased solid state switches. They never ensure a safe function when theyare not controlled (Important leakage current and untimely closing).Therefore, we advise you to use an electromechanical device in serieswith the softstarter, which can ensure a safe operation in thedisconnected circuit.

The emergency stop must not be done by the softstarter. It must

be done by an electromechanical with sufficient current breakingpossibility.

In order to operate in the circuit in safe condition, the controlpart of the softstarter will have to be disconnected from the control orauxiliary supplies as well.

ATTENTION

1- TheSMCVdoes not correctly operate on three phase mains with the motor neutralconnected to the neutral of the mains. If any, please contact us.

2- The overload relay must be adapted to the motor.3- Please take care not to make short-circuits while installing the by-pass contactor or the backward wires for delta

wiring.

4- The control voltage will have to be held sufficiently to allow the by-pass to close. Takecare not to remove the by-pass checking option "byp.".

5- In case of fast softstarting and softstopping controls without waiting for the end of the ramps, the motor may heat up.Please contact your motor supplier to choose an adapted model.

ADVISES FOR THE SETTINGS

ATTENTION

Obtaining a particular starting time value is only a consequence of the motor torque reduction and can not beguaranteed or easily repeatable. The rotary switch Time (s) setting values only give the duration of the voltage rampapplied to the motor but not necessarily its starting time. The main SMCVfunction is to obtain a motor torque reduction totake care of the motor load and the electric grid. The motor starting time is only a consequence and completely depends onthe motor itself, its load and the settings done by the user.

The SMCVcan not break a motor driving a load that has much inertia. The user can only obtain a stop time equalor longer than a simple disconnection from the electric grid. Using the softstop feature can only be justified when the motorload tends to break the motor (pumps, ) or when the products treated by the machine need to be stop slowly(conveyors,). In the case of load with high inertia, the softstop feature can help to reduce slowly the magnetic field insidethe motor to avoid long time overvoltage in the circuit.
