Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by
personnel qualified
for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.
Qualified personnel are those who, based on their training and experience, are capable of identifying risks and
avoiding potential hazards when working with these products/systems.

2.1
ESD Guidelines
ESD
All electronic devices are equipped with large-scale integrated ICs or components. Due to
their design, these electronic elements are highly sensitive to overvoltage, and thus to any
electrostatic discharge.
The acronym ESD has become the established designation for such electrostatic sensitive
components/devices. This is also the international abbreviation for such devices.
ESD devices are identified by the following symbol:
NOTICE
Electrostatic discharge
ESD devices can be destroyed by voltages well below the threshold of human perception.
These static voltages develop when you touch a component or electrical connection of a
device without having drained the static charges present on your body. The damage
caused to a device by overvoltage is usually not immediately evident and is only noticed
after an extended period of operation.
Electrostatic charging
Anyone who is not connected to the electrical potential of their surroundings can be
electrostatically charged.
The diagram below shows the maximum electrostatic voltage which may build up on a
person coming into contact with the materials specified in the diagram. These values
correspond to IEC 801-2 specifications.

SIRIUS 3RW30 / 3RW40
18 Manual, 10/2018, NEB535199502000/RS-AB/005
Basic protective measures against electrostatic discharge
●Make sure the grounding is good:
When handling electrostatic sensitive devices, ensure that your body, the workplace and
packaging are grounded. In this way, you can avoid becoming electrostatically charged.
●Avoid direct contact:
As a general rule, only touch electrostatic sensitive devices when this is unavoidable (e.g.
during maintenance work). Handle the devices without touching any chip pins or PCB
traces. In this way, the discharged energy cannot reach or damage sensitive devices.
Discharge your body before taking any necessary measurements on a device. Do so by
touching grounded metallic parts. Use only grounded measuring instruments.

2.2 Reactive power compensation

2.2
Reactive power compensation
Capacitors for improving the power factor (reactive power compensation)
Capacitors may not be connected to the output terminals of the 3RW52 soft starter.
Connecting capacitors to the output terminals will damage the 3RW52 soft starter.
Active filters, e.g. for reactive power compensation, must not be operated parallel to the
motor control device.
If capacitors are to be used to correct the power factor (actively or passively), they must be
connected on the line side of the device. They must not actively control the power factor
during the starting and coasting down phases. If a contactor disconnector or main contactor
are used together with the electronic 3RW52 soft starter, the capacitors must be
disconnected from the 3RW52 soft starter when the contactor is open.
2.3
Electromagnetic compatibility (EMC) according to IEC 60947-4-1
This product is designed for Environment A. It may produce radio interference in domestic
environments, in which case the user may be required to take adequate mitigation
measures.

Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines, and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions only form one element of such a concept.
Customer is responsible to prevent unauthorized access to its plants, systems, machines
and networks. Systems, machines and components should only be connected to the
enterprise network or the internet if and to the extent necessary and with appropriate security
measures (e.g. use of firewalls and network segmentation) in place.
Additionally, Siemens’ guidance on appropriate security measures should be taken into
account. You can find more information about industrial security by visiting:
https://www.siemens.com/industrialsecurity.
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends you apply product updates as soon as available and
always use the latest product versions. Use of product versions that are no longer supported,
and failure to apply latest updates may increase customer’s exposure to cyber threats.
