Compatibility (EMC) The following guidelines are provided for EMC installation compliance.
General Notes (Bulletin 294D only)
• The motor cable should be kept as short as possible in order to avoid
electromagnetic emissions as well as capacitive currents. CE conformity
of ArmorStart LT with EMC directive does not guarantee the entire
machine installation complies with CE EMC requirements. Many
factors can influence total machine/installation compliance.
• The EMI filter may result in relatively high ground leakage currents.
Therefore, ArmorStart LT must only be applied in installations that are
solidly grounded (bonded) to the building power distribution ground.
