Introduction 1
1.1 About the operating instructions
These operating instructions contain the information necessary for the safe operation and
intended use of the SICHARGEUCDispenser.
Safekeeping the operating instructions
The operating instructions are an integral part of the product and an indispensable part of the
product safety concept. The following requirements therefore apply for safekeeping the
operating instructions:
•Keep the operating instructions for the entire service life of the SICHARGEUCDispenser
•Make sure that all persons working with the equipment have easy access to the operating
instructions at all times
•When you transfer the SICHARGEUCDispenser to a third party, also transfer the operating
instructions
Using the operating instructions
How to use the operating instructions correctly:
•Make the operating instructions available to all persons involved before they start working
and while they are working on the SICHARGEUCDispenser
•Read the operating instructions before commencing work.
•Observe the safety information and handling instructions
Definition
•SICHARGEUCcharging station
The SICHARGEUCcharging station charges electric vehicles by converting alternating
voltage and alternating current into direct voltage and direct current.
•SICHARGEUCDispenser
The SICHARGEUCDispenser provides more charging points of a SICHARGEUC charging
station. You can connect up to five SICHARGEUCDispensers in series to a
SICHARGEUCcharging station as of 3kW rated power. The SICHARGEUCDispenser is an
interface between the vehicle and the charging station. The SICHARGEUCDispenser has a
small footprint. Using multiple SICHARGEUCDispensers increases the number of charging
points of a SICHARGEUCcharging station.

Intended use
Intended use of the SICHARGEUCDispenser is limited exclusively to the charging of batteries
of electric vehicles. For this, the electric vehicle must be equipped with a charging socket of
the type CCS Combo 2. The SICHARGEUCDispenser charges electric vehicles in accordance
with the EN62196‑3 and EN61851‑23 standards. Any other or additional use is not in
accordance with the intended use and constitutes misuse of the device. The
SICHARGEUCDispenser can be used indoors and outdoors. Observe the permissible ambient
conditions when used for the intended purpose.
Qualified personnel
All work on the SICHARGEUCDispenser may only be performed after having received the
proper instructions.
Non-electrical work, e.g. transport and assembly, may only be performed by qualified
personnel. Qualified personnel are qualified by training and experience to recognize risks
arising during the respective work and to avoid possible hazards.
Electrical engineering work may only be performed by qualified electricians themselves or
under their direction and supervision.A qualified electrician is someone who is able to assess
the work assigned to them and recognize potential dangers due to their professional training,
knowledge and experience as well as knowledge of the relevant standards.
Personal protective equipment (PPE)
Personal protective equipment protects you against hazards to your health and safety. Use
your personal protective equipment in accordance with occupational safety guidelines and
accident prevention regulations.
Fall arrester
When you are working at a height above 1m, use a fall arrester.
Use work platforms/lifting platforms to provide qualified personnel with a stable surface.
Take the necessary precautions to prevent tools and components from falling.
Fire and explosion protection
Do not store or use highly flammable liquids that produce flammable vapors, such as gasoline
or ethanol, in the proximity of the SICHARGEUCDispenser. Electrostatic charge or heat
generated during charging can ignite explosive and flammable liquids.
WARNING
Fire
In case of a fire, leave the danger zone.
Do not use the SICHARGEUCDispenser in case of a fire.

2.4 Industrial Security
SIEMENS AG provides products and solutions with industrial security functions that support
the secure operation of plants, systems, machines and networks.
Implement and maintain the industrial security concept
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. Systems, machines, and components should only be connected to
the enterprise network or the Internet if and to the extent that it is necessary and with
appropriate security measures in place (e.g. using firewalls and network segmentation).
In addition, the recommendations of Siemens regarding appropriate protective measures
should be observed. You can find additional information about Industrial Security at:
Industrial Security (http://www.siemens.com/industrialsecurity)
Only use current product versions
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. Using versions that are obsolete or are
no longer supported can increase the risk of cyber threats.
