User’s Manual

Important warnings for safety

Before any operation on either the mechanical or electrical parts of the installation, check that power

and control cables of the unit are isolated from voltage sources.

During operation the motor can be stopped by cancelling the run command but the starter remaind

powered up.

If personnel safety requires prevention of sudden restarts, this electronic locking system is not

sufficient: fit a breaker on the power circuit.

The starter is fitted with safety devices which, in the event of a fault, can stop the starter and

consequently the motor.

The motor itself may be stopped by a mechanical blockage. Finally, voltage variations or line supply

failures can also cause shutdowns.

If the cause of the shutdown disappears, there is a risk of restarting which may endanger machines,

installation or personnel. In this case the user must take precautions against the possibility of restarts,

example cut off the power.

This starter must be installed and set up in accordance with both international and national standards.

Bringing the device into conformity is the responsibility of the systems integrator who must observe the

EMC directive among others within the European Union. The specifications contained in this document

must be applied in order to comply with the essential requirements of the EMC directive.

The STE Soft Starter must be considered as a component: it is neither a machine nor a device ready for

use in accordance with European directives (machinery directive and electromagnetic compatibility

directive). It is the responsibility of the final integrator to guarantee conformity to the relevant

standards.

Warning:

This icon is present in all the operational procedures where the Improper

operation may result in serious personal injury or death

Caution:

This icon is present in all the operational procedures where the Improper

operation can cause damage for the SOFT STARTER.
