Rockwell Automation AK DBU - Dynamic Braking Unit 600/690 VAC - Manual (Page 31)

Appendix
B
CE Conformity
This appendix provides the installation and wiring instructions necessary
for the CE-conformity of the Dynamic Braking Unit.
Conformity with the Low Voltage (LV) Directive and Electromagnetic
Compatibility (EMC) Directive has been demonstrated using
harmonized European Norm (EN) standards published in the Official
Journal of the European Communities. The DBUs comply with the EN
standards listed below when installed according to the instructions
provided in the User Manual.
CE Declarations of Conformity are available online at:
http://www.ab.com/certification/ce/docs.
Low Voltage Directive (73/23/EEC)
• EN50178 Electronic equipment for use in power installations
EMC Directive (89/336/EEC)
• EN61800-3 Adjustable speed electrical power drive systems Part 3:
EMC product standard including specific test methods.
• The cable length between the DBU and inverter should be kept less
than 3m (10ft) in order to reduce electromagnetic emission as well as
capacitive currents. The inverter should be located in the same
cabinet or next to the cabinet with the DBU. If the connection leads
between DBU and inverter(s) leave the cabinet, shielded cables must
be used and cable length must be minimized.
• Cabinets should be designed for radiated EMC attenuation.
Recommended cabinets include Rittal TS8 series.
• Brake resistor assemblies should be mounted outside of the control
cabinet in a separate metal cabinet or screened enclosure designed to
dissipate the thermal energy.
• The DBU meets CE EMC emission limits for the industrial
