EMC stands for Electromagnetic compatibility. It is the ability of electric equipment to operate without
problems within an electromagnetic environment. Likewise, the equipment must not disturb or interfere
with any other product or system within its locality. This is a legal requirement for all equipment taken
into service within the European Economic Area (EEA).
Our products are designed with high standards of EMC in mind. Connect the power lines and groundings
along the instructions in this user guide to achieve the required level of EMI protection.
It is the responsibility of the installer to make sure that the equipment or system into which the product is
incorporated complies with the EMC legislation of the country of use. Within the European Union,
equipment into which this product is incorporated must comply with the EMC Directive 2014/30/EU.
Installation safety
Only trained and qualified personnel familiar with the relevant safety requirements can
install the electric device. If the electric device is installed incorrectly it may lead to safety
hazard.
Make sure of correct grounding connections. Do not run the electric device without correctly
attached protective earth conductor. The grounding cable must be sufficient to carry the
maximum supply fault current which is normally limited by the fuses or Miniature Circuit
Breaker (MCB). Suitably rated fuses or MCB should be fitted in the mains supply of the electric
device, by the local legislation and recommendations.
Use only correct (type and value) protective fuses with the high voltage DC-system.
Do not do any work on the electric device control cables when the power is applied to the
electric device or to the external control circuits.
The control input functions of the electric device – for example stop/start must be secured
using independent channel protection in safety critical applications. All applications where
malfunction could cause injury or loss of life must be subject to a risk assessment and improve
control signal protection if needed.
Do not activate the automatic fault reset function on any system, where this may cause a
potentially dangerous situation. Reason for every fault situation should be determined
before resetting the fault.
Make sure that the supply voltage corresponds to the specification of the electric device.
Do not attempt to repair the electric device. In the case of suspected fault or malfunction,
contact Danfoss or Danfoss authorized service center for further assistance.
