Electromagnetic compatibility (EMC)
When interfacing other equipment, connect only equipment that are speci ed as part of the system and that
are compatible with each other.
Magnetic and electromagnetic elds generated near current-carrying conductors and permanent magnets in electric
devices are a health danger to persons with heart pacemakers, metal implants and hearing aids. Persons with a heart
pacemaker, metal implants or hearing aids must consult a doctor before they enter the following areas:
Areas in which electric equipment and parts are operated.
Areas in which electric equipment with permanent magnets are stored, mounted, operated or repaired.
If necessary, do a special electromagnetic compatibility (EMC) test on the installation.
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).
The products are designed with high standards of EMC in mind. Connect the power lines and
groundings by the instructions in this user guide to achieve the required level of EMC 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.
Installation safety
Only trained and quali ed 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 tted 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 speci cation of the electric device.
