Applications

3.1.12
High-Efficiency Motors
Due to an inherently steep front to the speed/torque curve, high efficiency motors can exhibit
instability when lightly loaded and the optimising rate parameter P19 may need adjusting to
compensate.
3.1.13
EU Compliance with the EMC Directive
When considering the use or fitting of any Soft Starter, users and installers in European
countries must comply with the EMC Directive 89/336/EEC. The manufacturer of the soft-
starter has a statutory obligation to provide a guide for compliance with this directive.
For the QFE, this guidance is given in the EMC guide which is section 4 of this manual. It is
essential that users and installers understand and comply with the requirements described
in these sections.
3.1.14
Fuses
Circuit protection fuses should be rated at twice the motor rated current for normal low-
inertia applications. See also section 3.2.2 relating to high inertia loads.
Semiconductor fuses are available for the short circuit protection of the thyristors in the QFE.
See section 2.10 of the Electrical Installation manual for Semiconductor fuse recommendations
and details of the Overload incorporated into the QFE.
