Precautions for EMC, Models SJ700-1850 to -4000

The SJ700
(EMC) Directive (2004/108/EC). However, when using the inverter in Europe, you must
comply with the following specifications and requirements to meet the EMC Directive and
other standards in Europe:
WARNING: This equipment must be installed, adjusted, and maintained by qualified
engineers who have expert knowledge of electric work, inverter operation, and the hazardous
circumstances that can occur. Otherwise, personal injury may result.
Use the following checklist to ensure the inverter is within proper operating ranges and
conditions.
