Notes on Safety
This document contains notes that must be adhered to for your own personal safety and to
avoid damage to property. Keep it safe for later usage.
However, it does not constitute a complete description of all safety measures required for
installation, service, and maintenance of the device in question. Details are to be taken from
the manuals and those are mandatory.
Warning: Danger of severe personal injury or substantial damage to property
Hazardous voltages may occur in devices and modules during operation depending on
the design and application. Always observe the instructions given in "Qualified
Electrical Engineering Personnel" below.
Qualified Electrical Engineering Personnel
Qualified electrical engineering personnel may commission and operate the device
described in this document. Qualified electrical engineering personnel in the sense of this
document are people who can demonstrate up to date technical qualifications as electrical
technicians including safety and first aid training. These persons may commission, isolate,
ground and label devices, systems and circuits according to the standards of safety
engineering.
Use as Prescribed
The device may only be used for such applications as set out in the catalogs and the
technical description, and only in combination with third party equipment recommended and
approved by Siemens.
Correct and safe operation of the product requires adequate transportation, storage,
installation and mounting in a control cabinet, as well as appropriate use and maintenance.
During operation of electrical equipment, it is unavoidable that certain parts of this
equipment will carry dangerous voltages. Severe injury or damage to property can occur if
the appropriate measures are not taken:
• Before making any connections, ground the equipment and the grounding terminal.
• Hazardous voltages can be present on all switching components connected to the power
supply.
• The device does not represent a safety-oriented application.
• Even after the supply voltage has been disconnected, hazardous voltages can still be
present in the equipment (capacitor storage).
• The limit values indicated in the manual must not be exceeded; that also applies to
testing and commissioning.
Statement of Conformity
The product described conforms to the regulations of the following European
Directives:
• EMC Directive 2014/30/EU
(observance of the harmonized standard EN 60870-2-1:1996)
• Low Voltage Directive 2014/35/EU
(observance of the harmonized standard EN 61010-1:2010, EN 61010-2-201:2013)
• RoHS Directive 2011/65/EU
(observance of the harmonized standard EN 50581:2012)
Used Symbols (additional symbols are described in the manual)
Warning, risk of electric shock
Caution, risk of danger. The
documentation must be observed.
Application
The SICAM I/O module DO-8221 is a digital output module for secured command output. It
is used to expand SICAM A8000 systems.
The SICAM A8000 series is suitable for electrical distribution substations, gas distribution
substations, hydropower plants, pipelines and railway power supplies.
DO-8221 Product Information

Unpacking a Device
• Check the package for external transport damage. A damaged packing may indicate that
the device inside is also damaged.
• Unpack the device carefully; do not use force.
• Visually check the device to ensure that it is in perfect mechanical condition.
• Return a damaged device to the manufacturer or dispose it correctly. A defective device
may not either be used nor repaired by the user.
Note: Before commissioning the device, leave it in the operating room for at least
2 hours. This allows it to reach room temperature and prevents dampness and
condensation.
Mounting
Precondition for mounting the I/O module is that the SICAM A8000 system to be expanded
has already been mounted on the DIN rail.
Then the bus connector supplied with the I/O module is clicked on the DIN rail to the right of
the mounted system and pressed into the connector of the left adjacent module. Afterwards
plug the I/O module on the bus connector.
Note: For details about the mounting refer to the relevant manual (SICAM A8000
Series CP-8050 Manual).
Restriction: The I/O module may only be installed horizontally!
Commissioning
• Check the adherence of the specified limit values.
• Connect the process-devices to the screw terminals. Cabinet-internal wiring is preferably
carried out with plastic-insulated cables according to DIN VDE 298 T4 2/89.
Types: H05V-K, H05V2-K (0.5...1 mm²) or H07V-K, H07V2-K (1.5...2.5 mm²).
Use only copper wires.
• Use only SF/UTP, SF/FTP or S/FTP cables (Cat.6A) for the EbIO bus to CI-853x.
Siemens recommends the usage of 6XV1878-2A, 6XV1870-3QH or 6XV1870-3QN.
• Use only shielded RJ45 connectors. Consider a reliable and durable contacting of the
cable shield with the RJ45 shield.
• Communication cables must be installed separately from the supply and peripheral
cables.
• The SICAM I/O module is supplied with voltage via the bus.
