INSTALLATION
DANGER!
IMPORTANT
The installation of this product must be done by qualified people,
informed about electric hazards (electrocution risks linked to the
voltage levels in the circuit).
Any intervention on the installation must be operated the circuit
disconnected from the electric grid by an electromechanical mean
insuring a sufficient galvanic isolation.
The device concerned by this document is composed of silicon
based solid state switches. They never ensure a safe function when they
are not controlled (Important leakage current and untimely closing).
Therefore, we advise you to use an electromechanical device in series
with the softstarter, which can ensure a safe operation in the
disconnected circuit.
The emergency stop must not be done by the softstarter. It must
be done by an electromechanical with sufficient current breaking
possibility.
In order to operate in the circuit in safe condition, the control
part of the softstarter will have to be disconnected from the control or
auxiliary supplies as well.
ATTENTION
1- The SMCV does not correctly operate on three phase mains with the motor neutral
connected 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- In case of devices planned to be used connected to a by-pass contactor (SMCW…1 reference), the control voltage will
have to be held sufficiently to allow the by-pass to close. Take care 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.
