SAFETY INSTRUCTIONS
ALARM – SAFETY – CAUTION
Power factor compensation capacitors.
The reactive compensation capacitors used to increase the power factor should be connected to the soft
starter input terminals and not to the output ones. These capacitors should be connected with an
additional contactor as shown in the electric connections section. The connection will be done only when
the soft starter is running and it will be disconnected during the acceleration and deceleration ramp.
Otherwise, the soft starter can be damaged.
When working in electric installations always remember to apply the 5 golden rules:
1. Visible cut of all the voltage sources.
2. Mechanic lock of every single cut elements.
3. Verify no voltage is present.
4. Earth ground and short circuit any possible voltage source.
5. Define and post sign the working area.
CAUTION
Handle the equipment with dry hands.
Otherwise, electric shock hazard existence.
Do not use cables with damaged insulation. Do not summit cables to abrasions, excessive stress,
heavy loads or pinching.
Otherwise, electric shock hazard existence.
Keep clean the equipment, not allowing lint, paper, wooden chips, dust, metallic chips or other
foreign matter (screws, pressure washers…) into the soft starter. Verify this point after the
installation.
Otherwise, accident and fire risk existence.
Place the soft starter over non-flammable surface. Keep away from flammable materials.
Otherwise, fire risk existence.
Disconnect and earth ground the soft starter power input when the soft starter is damaged.
Otherwise, fire and secondary accident risk existence.
After applying input voltage or after removing it, the soft starter will remain warm for a couple of
minutes.
Otherwise, body injury or skin burn risk existence.
Do not apply voltage to a damaged or soft starter with parts missing even if the installation is
complete.
Otherwise, electric shock hazard existence.
Do not exchange the soft starter input and output power connections.
Otherwise, excessive voltage could be found in the logic control circuit.
