! Important Notice on Product Safety

DANGER - RISK OF ELECTRICAL SHOCK OR DEATH - FOLLOW ALL INSTALLATION INSTRUCTIONS.

The system complies with the standard EN 60950 / IEC 60950. All equipment connected to the system mustcomply with the applicable safety standards.Hazardous voltages are present at the AC power supply lines in this electrical equipment. Some components mayalso have high operating temperatures.Failure to observe and follow all installation and safety instructions can result in serious personal injuryor property damage.Therefore, only trained and qualified personnel may install and maintain the system.

The same text in German:

Wichtiger Hinweis zur Produktsicherheit

LEBENSGEFAHR - BEACHTEN SIE ALLE INSTALLATIONSHINWEISE.

Das System entspricht den Anforderungen der EN 60950 / IEC 60950. Alle an das System angeschlossenenGeräte müssen die zutreffenden Sicherheitsbestimmungen erfüllen.In diesen Anlagen stehen die Netzversorgungsleitungen unter gefährlicher Spannung. Einige Komponentenkönnen auch eine hohe Betriebstemperatur aufweisen.Nichtbeachtung der Installations- und Sicherheitshinweise kann zu schweren Körperverletzungen oderSachschäden führen.Deshalb darf nur geschultes und qualifiziertes Personal das System installieren und warten.

Caution:This equipment has been tested and found to comply with EN 301489. Its class of conformity is defined in tableA30808-X3247-X910-*-7618, which is shipped with each product. This class also corresponds to the limits for aClass A digital device, pursuant to part 15 of the FCC Rules.These limits are designed to provide reasonable protection against harmful interference when the equipment isoperated in a commercial environment.This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accor-dance with the relevant standards referenced in the manual “Guide to Documentation”, may cause harmful inter-ference to radio communications.For system installations it is strictly required to choose all installation sites according to national and local requi-rements concerning construction rules and static load capacities of buildings and roofs.For all sites, in particular in residential areas it is mandatory to observe all respectively applicable electromagneticfield / force (EMF) limits. Otherwise harmful personal interference is possible.
