The expression HBES/BACS covers any combination of HBES and/or BACS
24、products including their separate connected/detachable devices linked together via one or more networks. Part 5 of this series applies to HBES/BACS devices to ensure a common level of EMC requirements. BS EN 50491-5-2:2010 5 EN 50491-5-2:2010 1 Scope The scope of EN 50491-5-1:2010 applies, with the
25、following modification: Replace the 3rdparagraph by the following ones: This is the specific part of EN 50491-5 for HBES/BACS used in residential, commercial and light industry environment.
