connector of the electric machine. You can connect the temperature signal to the temperature
surveillance pin in the inverter (EC-C) and make sure that the inverter has the machine temperature
protection feature activated.
The electric machine can be ordered with bearing temperature measurement. This option includes one
PT100 temperature sensor at both D-end and N-end bearings. The signal can be read out using a
separate connector at both ends.
The electric machine has leakage sensors (2pcs) at the lower part of the electric machine. This feature is
useful in moist conditions to detect possible excessive water in contact with the electric machine.
Separate connectors for both leakage signals exist.
Electromagnetic compatibility (EMC)
When interfacing other equipment, connect only equipment that are specified as part of the
system and that are compatible.
Magnetic and electromagnetic fields generated near the current-carrying conductors and
permanent magnets in electric machines represent 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, perform 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).
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.
