Declaration of conformity
The DDMP Driver product is conform to the relevant safety provisions of the Low Voltage Directive
2006/95/EC and the EMC Directive 2004/108/EC and has been designed and manufactured in accordance
with the following harmonized European standards:
• EN 61000-3-2 “Electromagnetic compatibility (EMC) - Part 3-2: Limits - Limits for harmonic current
emissions (equipment input current <= 16 A per phase)”.
• EN 61000-6-3 “Electromagnetic compatibility (EMC) - Part 6-3: Generic standards - Emission
standard for residential, commercial and light-industrial environments”.
• EN 61000-6-4 “Electromagnetic compatibility (EMC) - Part 6-4: Generic standards - Emission
standard for industrial environments”.
• EN 61800-3 EMC Product Standard for Power Drive Systems.
Electromagnetic Compatibility
The DDMP product is designed with high standards of EMC in mind. The Driver, suitable for use within the
European Union, is fitted with an internal EMC filter. This EMC filter is designed to reduce the conducted
emissions back into the supply through the power cables for compliance with harmonised European
standards.
It is the responsibility of the installer to ensure 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 2004/108/EC.
To improve the Electromagnetic compatibility
A ferrites model Wurth 742 717 22
can be put on the power supply cable
(close to the driver).

The compliancy to the standards are intended for a single fan.
No tests have been made on multiple installations.
The zero series of the 2KW Driver (LOT 20151020 01) does not comply with the limits of
category C1 (EN 61800-3).
Further series will be compliants.
Product overview
General Information
The DDMP is a forward curved blade fan equipped by an external permanent magnet rotor motor. The
rotor magnets are made by rare earths (NdFeB) that strongly reduce the motor dimension and therefore
the fan obstruction. The motor shape itself has been chosen for increasing the airflow inside the fan scroll.
The Driver is compact and it’s directly installed on board of the fan. It is equipped with an active PFC and it
drives the motor through a sensorless algorithm.
