The electronic 3RW44 soft starters are designed for normal starting. A model
with a higher output may be necessary for heavy starting or for a higher starting
frequency.
A PTC thermistor in the motor is recommended for long starting times. This also
applies to the soft stop, pump stop and DC braking stopping modes, since during
the stopping time, there is an additional current load in contrast to coasting
down.
Capacitive elements (e.g. compensation systems) must not be included in the
motor branch between the soft starter and the motor. Active filters must not be
operated in combination with soft starters.
All elements of the main circuit (such as fuses and switching devices) must be
dimensioned for direct on line starting according to the local short-circuit
conditions, and should be ordered separately.
The harmonic component load of the starting current must be taken into account
when selecting circuit breakers (release selection).
The electronic 3RW44 soft starters are equipped with a PC interface to
communicate with the Soft Starter ES software and an operating and monitoring
module (display).
This software allows all SIEMENS soft starters to be simulated and selected
using various parameters such as network conditions, motor data, load data,
special application requirements, etc.
The software is a powerful tool which makes time-consuming and complex
manual calculations for determining the suitable soft starter a thing of the past.

Siemens offers a two-day training course on electronic SIRIUS soft starters to
keep both our customers and Siemens personnel up-to-date on configuration,
commissioning and maintenance.
