Page 3: Safety
1.1.1 Warnings The Danfoss harmonic filter AHF 005 and AHF 010 contain dangerous voltages when connected to mains voltages. Only a competent electrician should carry out the electrical installation. Improper installation of the filter or the connected frequency converter may cause equipment failure, serious injury or death.
Page 4: Avoid Filter Module Damage
AHF 005/010 Operating Instructions 1.1.4 Avoid Filter Module Damage The filter modules may only be used with Danfoss frequency converters. Do not use the drive system (frequency converter, motor load and filter) if the equipment has been damaged. Modifications of the filters are not allowed.
Page 5: Ordering Numbers
The Danfoss AHF 005 and AHF 010 are advanced harmonic filters not to be compared with traditional harmonic trap filters. The Danfoss harmonic filters have been specially designed to match all the Danfoss frequency converters. The filters AHF 010 and AHF 005 are available in five voltage versions.

Table 2.2: AHF 005 and AHF 010, 380V - 415V, 50Hz ⋆ Please note that the matching of the typical Danfoss frequency converter and filter is pre-calculated based on 400V and assuming typical motor load (4 or 2 pole motor). (FC 300 is based on an 160% torque application, while FC 100 and FC 200 Series are based on 110% torque application.) The pre-calculated filter current may be different than the input current ratings of FC 100, FC 200 and FC 300 series as stated in the respective operating instructions, as these numbers are based on different operating conditions.

Page 15: Installation
AHF 005/010 Operating Instructions 4 Installation 4 Installation 4.1.1 Mechanical Installation The encapsulation of the filters have an IP 20 rating. The filters can be mounted side by side with 60 mm (2,36 inches) clearance. To other components and to the cabinet walls keep a horizontal clearance of at least 70 mm (2,76 inches) and a vertical clearance of at least 150 mm (5,91 inches).

5306 W Table 4.1: Max. heat losses at full load under-voltage. If other heat sources (e.g. Danfoss frequency converters) are installed in an enclosure with the harmonic filter AHF 0xx, this heat generation must also be considered when calculating required airflow If the cooling air is polluted (dust, dirt swirl, grease, aggressive gas) the function of the filter module may be impeded.
Page 17 A maximum cable lenght of 2 meters are allowed between filter and contactor. * Power wiring used for connection of the filter AHF 005 and AHF 010 in enclosure size E, F and G must be terminated with cable lugs that can be attached to the input and output bus bars terminals.
Page 18: Capacitor Disconnect
4.1.4 Capacitor Disconnect The power factor of the harmonic filter AHF 005/010 is decreasing with decreasing load. At zero load the Power Factor becomes zero and the capacitors produce approximately 30% leading current compared to the rated current of the filter. The reactive current generated by the filter at partial load is normally not of any concern, mainly because of the small current compared to the system capacity (max.

Page 21: Fuses
The filter must be protected against short-circuit and overload to avoid electrical or fire hazard and to protect cables and filter from overheating. Danfoss recommends using fuses mentioned below to protect service personnel and equipment in case of an internal failure in the filter.
Page 22: Over Temperature Switch
See the section on fuses in the 4.1.6 Over Temperature Switch The Danfoss harmonic filters AHF 005 and AHF 010 are equipped with a galvanic isolated thermal switch (not PELV), that is closed under normal operating conditions and open if the filter is overheated.
