This is a product for environment A. When used in a household setting, this device can cause unwanted radio interference. In this case the user 

may be required to carry out appropriate measures to avoid such radio interference.

1. Switch off soft starter

(IN 1 -> 0).

2. Reduce starting time.

(Turn potentiometer anti-

clockwise)

1. Switch soft starter 

off (IN 1 -> 0).

2. Increase starting 

time. (Turn potentio-

meter clockwise)

1. Switch off soft starter

(IN 1 -> 0).

2. Increase start voltage. 

(Turn potentiometer clock-

wise)

1. Switch soft starter off 

(IN 1 -> 0).

2. Reduce start voltage. 

(Turn potentiometer 

anti-clockwise)

The motor reaches 

its nominal rotational 

speed

- significantly faster 

than in the specified 

ramp time

- not at all 

(motor stuck)

The motor 

hums and 

does not start 

immediately

Motor: 

The motor starts 

with a sudden 

increase in 

torque

Quick commissioning of

the 3RW30 SIRIUS 

soft starter

1. Wiring control

- Control part and

- Performance part

2. Configure device

Set the soft start function

- Starting time (s)

- Start voltage (%)

to the desired value 

(see table for suggested settings).

3. Check and connect the 

voltages in the control and 

main circuits.

Check the supply voltage on 

terminals A1 and A2.
