Declaration of Conformity
Lafert Group hereby states that the HP Combi Flow product range conforms to the relevant safety provisions of the following council directives:
2014/30/EU (EMC) and 2014/35/EU (LVD)
Design and manufacture is in accordance with the following harmonised European standards:
EN 61800-5-1:2007:A11:2021 Adjustable speed electrical power drive systems. Safety requirements. Electrical, thermal and energy.
EN 61800-3:2018
Adjustable speed electrical power drive systems. EMC requirements and specific test methods.
EN61000-3-12:2021
Limits for harmonic currents produced by equipment connected to public low-voltage systems with input current >
16 A and <= 75 A per phase.
Three phase 200V and three phase 400V HP Combi Flow products comply with IEC 61000-3-12 with respect
to the THC without the need for Line Reactors, provided that the short-circuit power

Electromagnetic Compatibility
All HP Combi Flows are designed with high standards of EMC in mind. All versions intended for use within the European Union are fitted with an
internal EMC filter. This EMC filter is designed to reduce the conducted emissions back into the supply via 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 2014/30/
EU. This User Guide provides guidance to ensure that the applicable standards may be achieved.

2 Year Warranty:
All Lafert Group HP Combi Flow units carry a 2 year warranty against manufacturing defects from the date of
manufacture. The manufacturer accepts no liability for any damage caused during or resulting from transport, receipt of delivery, installation
or commissioning. The manufacturer also accepts no liability for damage or consequences resulting from inappropriate, negligent or incorrect
installation, incorrect adjustment of the operating parameters of the drive, incorrect matching of the drive to the motor, incorrect installation,
unacceptable dust, moisture, corrosive substances, excessive vibration or ambient temperatures outside of the design specification.

Lafert Group adopts a policy of continuous improvement and whilst every effort has been made to provide accurate and up to date information, the
information contained in this User Guide should be used for guidance purposes only and does not form the part of any contract.
When installing the drive on any power supply where the phase-ground voltage may exceed the phase-phase voltage (typically IT
supply networks or Marine vessels) it is essential that the internal EMC filter ground and surge protection varistor ground (where fitted) are
disconnected. If in doubt, refer to your Sales Partner for further information.
This manual is intended as a guide for proper installation. Lafert Group cannot assume responsibility for the compliance or the non-
compliance to any code, national, local or otherwise, for the proper installation of this drive or associated equipment. A hazard of
personal injury and/or equipment damage exists if codes are ignored during installation.
This HP Combi Flow contains high voltage capacitors that take time to discharge after removal of the main supply. Before working on
the drive, ensure isolation of the main supply from line inputs. Wait ten (10) minutes for the capacitors to discharge to safe voltage levels.
Failure to observe this precaution could result in severe bodily injury or loss of life.
Only qualified electrical personnel familiar with the construction and operation of this equipment and the hazards involved should
install, adjust, operate, or service this equipment. Read and understand this manual and other applicable manuals in their entirety before
proceeding. Failure to observe this precaution could result in severe bodily injury or loss of life.
