Safety Information and Precautions

Electrical Shock Hazard
Ensure the protective earthing conductor complies with technical standards and local safety regulations� Because the leakage current
exceeds 3�5 mA in all models, IEC 61800-5-1 states that either the power supply must be automatically disconnected in case of
discontinuity of the protective earthing conductor or a protective earthing conductor with a cross-section of at least 10 mm
2
(Cu) or 16
mm2 (Al) must be used� Failure to comply may result in death or serious injury�
When using an earth leakage circuit breaker, use a residual current operated protective device (RCD) of type B (breaker which can
detect both AC and DC)� Leakage current can cause unprotected components to operate incorrectly� If this is a problem, lower the carrier
frequency, replace the components in question with parts protected against harmonic current, or increase the sensitivity amperage of the
leakage breaker to at least 200 mA per drive�
Factors in determining leakage current:
•
Size of the AC drive
•
AC drive carrier frequency
•
Motor cable type and length
•
EMI/RFI filter

Approvals
CE mark indicates compliance with European safety and environmental regulations� It is required for engaging in business and
commerce in Europe�
European standards include the Machinery Directive for machine manufacturers, the Low Voltage Directive for electronics manufacturers,
and EMC guidelines for controlling noise�
The drive with CE mark meets the following EMC guidelines and the Low Voltage Directive�
•
2014/35/EU: Low Voltage Directive
•
2014/30/EU: Electromagnetic compatibility
Machines and devices used in combination with this drive must also be CE certified and marked. The integrator who integrates the drive
with the CE mark in into other devices has the responsibility of ensuring compliance with CE standards and verifying that conditions meet
European standards�
