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.

Equipment Manual, 07/2020, L1V30579222003-03 7
Introduction
1
This manual contains all information required to commission and use the 7KN Powercenter
3000. It is aimed both at programmers and testers who commission the device themselves
and connect them to other units, e.g. energy monitoring, automation systems or SCADA
systems, and at service and maintenance technicians who install expansions or perform error
analyses.
Required basic knowledge
In addition to knowledge about the design of a low-voltage power distribution system, basic
knowledge of Ethernet technology and industrial communication is required.
Scope of validity of this document
This manual applies to all V1.x versions of the 7KN Powercenter 3000.
Conventions
In this documentation, the term "Device" is used instead of the product label
7KN Powercenter 3000.

2.1 General safety information
WARNING
The safety of a system in which the device is integrated is the responsibility of those
who install the system.
There is danger of a malfunction resulting in death of serious injury.
•
Ensure only qualified personnel perform work.
WARNING
Lethal voltage when the control cabinet is open.
If you install the device in a control cabinet, individual areas or components in the control
cabinet might be carrying a lethal voltage. If you touch these areas or components, this can
result in death due to electric shock.
•
Disconnect the control cabinet completely so that it is dead before opening it.
System expansions
NOTICE
Damage due to system expansions
Device and system expansions can be faulty and affect the entire machine or plant.
Installation of expansions can damage the device, machine or plant. Device or system
expansions can violate safety rules and regulations relating to interference suppression.
The warranty is voided if you cause faults in the device due to installation or replacement of
system expansions.

Battery
WARNING
Danger of explosion and danger of release of harmful substances
Improper handling of lithium batteries can result in explosion of the batteries.
Explosion of the batteries and the resulting release of harmful substances can result in
serious injury. Worn batteries endanger the function of the device.
When handling lithium batteries, please note:
•Replace depleted batteries in a timely manner, see Replacing backup battery (Page 114).
•Replace the lithium battery only with identical types or types recommended by the
manufacturer (Order No.: A5E34345932).
•Do not throw batteries into a fire, do not solder on the body of the cell, do not recharge,
open, or short-circuit batteries, do not connect batteries with incorrect polarity, do not
heat batteries above 100 °C (212 °F), and protect batteries from direct sunlight, humidity
and condensation.
Radio-frequency radiation
NOTICE
Consider immunity to interference due to radio-frequency radiation
The device has enhanced immunity to interference caused by radio-frequency radiation in
accordance with the electromagnetic compatibility specifications in the technical data.
Irradiation above the specified immunity levels can impair the function of the device, result
in malfunctions and injury or damage to property.
Note the specifications for immunity to interference caused by radio-frequency radiation in
the technical data.

Safety information
2.2 Security information
7KN POWERCENTER 3000
Equipment Manual, 07/2020, L1V30579222003-03 11
2.2 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 constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be connected
to an enterprise network or the Internet if and to the extent such a connection is necessary
and only when appropriate security measures (e.g. firewalls and/or network segmentation)
are in place.
For additional information on industrial security measures that may be implemented, please
visit (https://www.siemens.com/industrialsecurity).
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends that product updates are applied as soon as they are
available and that the latest product versions are used. Use of product versions that are no
longer supported, and failure to apply the latest updates may increase customer's exposure to
cyber threats.
To keep up to date with all the latest product updates, subscribe to the Siemens Industrial
Security RSS Feed at (https://www.siemens.com/industrialsecurity).
2.3 Information on use
NOTICE
Possible functional restrictions when the function of the plant has not been validated
The device is tested and certified based on the technical standards. In rare cases, functional
restrictions can occur during operation of your plant.
To avoid functional restrictions, validate the correct function of the plant.
Note
Use in
industry without additional protective measures
The device was designed for use in a normal industrial environment in accordance with
IEC 60721-3-3.
NOTICE
Cleaning
Clean the surface of the housing with a damp cloth and make sure that no water enters the
interior of the device.
