  Monitoring of large plants Large plants generate high levels of profitable salesrevenues. For this reason good monitoring is all the moreimportant. The new Solar-Log ™ String Connection Box monitors every indi-vidual string and was deliberately developed or successul dataevaluation by the Solar-Log ™ . Strict adherence to a undamentalimportance o quality was involved in the selection o materials. All components used comply with current DIN and VDE stand-ards. The SCB “Made in Germany” adheres to the highest stand-ards o quality. With Solar-Log ™ SCB and Solar-Log 1000  large plants can be monitored TypeArt.-No. Solar-Log ™ SCB 12 DC / DC 255115 Solar-Log ™ SCB 16 DC / DC 255123Highest standards of operational safety  Design rated to 900 V system voltage (with supply rom mod-ules via internal DC / DC mains power unit) on all componentsup to terminals and cables.  1100 V, 160 A load circuit breakers or reliableall-terminal DC disconnection at ull load.  Class I / II, “B / C” overvoltage protection as well as stringprotection on the positive and negative terminal orcomprehensive protection o connected modules.  High temperature stability in continuous operating mode(while adhering to “synchronicity”). Ease of assembly The powder-coated aluminium housing complies with protection standard IP65 and is able to withstand severe weathering withoutany difculty. Clearly defned connections with contact protection inside the box assure high levels o reliability. All connections insidethe String Connection Box are readily accessible and thereore simpliy the task o installation. Voltage supply to the box is achievedby the DC voltage o the modules. For operational purposes, no external power supply cable needs to be routed. The SCB is completelypreassembled at the time o delivery and is ready to be connected.
