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. Follow this manual and install according to National Electrical Codes and local safety codes.
Operation of the harmonic filter is only allowed when the filters housing lid, door or cover is closed.
1.1.2 Symbols Used in This Manual
This manual contains different symbols that require special attention. The symbols used are the following:
Warning of hazardous electrical voltage.
Warning of a general danger.
NB!
This note designates general, useful notes. If you observe it, handling of the filter/drive system is made easier.
1.1.3 Operator's Safety
After mains disconnections, the power terminals X1.1, X1.2, X1.3, X3.1, X3.2, X3.3, X4.1, X4.2 and X4.3 remain live for minimum 4
minutes.
The filters have to be installed in a way, that they fulfil their function and don’t expose persons to danger. They have to be mounted
correctly and used in accordance with their purpose.

2.1.1 Description
The Danfoss harmonic filters AHF 005 and AHF 010 are ensuring near sinusoidal mains current, minimising the harmonic current emission into the mains
supply. 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.
• 380 - 415 V AC, 50 Hz
• 380 - 415 V AC, 60 Hz
• 440 - 480 V AC, 60 Hz
• 500 - 525 V AC, 50 Hz
• 690 V AC, 50 Hz
The Danfoss AHF 010 and AHF 005 have the following characteristics:
• Small compact housing that fits into a panel
• Easy to use in retrofit applications
• AHF 010 reduces the total harmonic current distortion to 10%*
•AHF 005 reduces the total harmonic current distortion to 5%*
• Current rating from 10A - 370A
• AHF Filters can be paralleled for higher power modules
• One filter module can be used for several frequency converters
• High efficiency (> 0.98)
• User-friendly commissioning - no adjustment necessary
• No routine maintenance required
*THiD of 10% or 5% will be achieved when the following conditions are met:
-THvD of the system without the drive operating is less than 2%
-Filter is operating at nominal load
If these conditions are not fulfilled, a significant reduction of the harmonic distortion can still be achieved, but the rated THiD values may not be achieved.
The mains quality has to be according to EN61000-2-4 level 3, allowing a maximum THvD level of 10%.

2.1.7 Calculation of the Exact Filter Size Needed
NB!
For optimal performance the harmonic filter should be sized for the mains input current to the frequency converter, i.e. the input current
drawn based on the expected load of the frequency converter and not the size of the frequency converter itself!
The mains input current to the frequency converter (IFC,L) can by calculated using the nominal motor current (IM,N) and displacement power factor (Cos
φ)) of the motor. Both data are normally printed on the nameplate of the motor. In the case where the nominal motor voltage (U M,N) is unequal to the
actual mains-mains voltage (UL) the calculated current must be corrected with the ratio between these voltages as shown in the equation below.
IFC
, L
= 1.1 × IM
, N
× Cos
(ϕ)×
((
UM
, N
)/(
UL
))
The harmonic filter chosen must have a nominal current (IAHF,N ) equal to or larger than the calculated frequency converter mains input current (IFC,L).
If several frequency converters are to be connected to the same filter, the harmonic filter must be sized according to the sum of the calculated mains
currents.
If the harmonic filter is sized for the load, and the motor of the corresponding frequency converter is changed, the current must be
re-calculated to avoid overload of the harmonic filter.

NB!
The reduction of the low harmonic current emission to the rated THiD implies, that the THvD of the non-influenced mains voltage is
lower than 2% and the ratio of short circuit power to installed load (R SCE ) is at least 66. Under these conditions the THiD of the mains
current of the frequency converter is reduced to 10% or 5% (typical values at nominal load). If these conditions are not or only partially
fulfilled, a significant reduction of the harmonic components can still be achieved, but the rated THiD values may not be achieved.

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).
Only vertical installation is allowed (mains terminal at bottom).
For versions with bus bars (frame size E – H) it is nec-
essary to mount the added covers to the connectors in
order to achieve the protection type IP 20.
Illustration 4.1: Clearance surrounding the AHF filter
Below picture series shows mounting principles. All filters in frame E to H have to be mounted with an added terminal kit to comply with IP20 enclosure
rating. Please make sure that the terminal plastic cover back plate (see photo below) is mounted and fixed correctly before adding the terminal cover.

NB!
Unit does not comply with IP20 rating if plastic back plate or terminal cover is omitted.
4.1.2 Ventilation
The filters are cooled by means of air circulation. Consequently, the air needs to be able to move freely above and below the filter module. The efficiency
of the filter modules is greater than 0.98. When installing a filter module in a panel or another enclosure, ensure there is sufficient airflow though the
enclosure to limit heat rise in the enclosure.

Table 4.1: Max. heat losses at full load under-voltage.
NB!
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
NB!
If the cooling air is polluted (dust, dirt swirl, grease, aggressive gas) the function of the filter module may be impeded. Ensure sufficient
countermeasures, e.g. separate cooling air, mounting of air filters, periodical cleaning.
4.1.3 Cable lengths and cross sections
The installation of our frequency converters in combination with AHF filters allow for a high freedom of installation flexibility. Cable cross section has to
be in accordance with data in the table below and cable lenght has to be limited to 50 meters. It is adviced to use unscreened cables between the AHF
filter and the drive.
Power wiring
Standard connection
Supply voltage must be connected to the terminals X1.1, X1.2 and X1.3. The frequency converter supply terminals L1, L2 and L3 must be connected to
the filter module terminals X2.1, X2.2 and X2.3.
Paralleling of FC's
If several frequency converters are to be connected to the harmonic filter, the connection is similar to the standard connection - The supply terminals
L1, L2 and L3 of several frequency converters must be connected to the filter module terminals X2.1, X2.2 and X2.3.

NB!
If several VLT frequency converters are to be connected to the same filter, the harmonic filter must be sized according to the sum of
the calculated input current to the VLT frequency converters.
Filters in parallel
If the mains input current of the frequency converter exceeds the nominal current of the largest harmonic filter, several harmonic filters can be paralleled
to achieve the necessary rating. Supply voltage must be connected to the terminals X1.1, X1.2 and X1.3 of the filters. The frequency converter supply
terminals L1, L2 and L3 must be connected to the filter modules terminals X2.1, X2.2 and X2.3.
NB!
Filters of different current ratings can be wired in parallel. The rating of the filter becomes the sum of the individual current ratings.

NB!
The cable length between the filter and the capacitor disconnect contactor has to be as short as possible in order to reduce the impedance influence
of the cable. 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. This type of termination imposes no specifications of the minimum and maximum cable size suitable for
connection. Power terminal details regarding the bus bars can be found in the figures below.
NB!
Do not fix the nut without using a second wrench for the screw.
If this is not observed, it might be possible to tear out the terminal when fixing the nut.

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. 30%) as well as the fact that other load normally
compensates the capacitive current.

In applications where this reactive current may not be accepted, Terminals X3.1, X3.2, X3.3 and X4.1, X4, X4.3 are giving acces to the filter capacitors.
As default (on delivery) the wiring will shorten Terminal X3.1 with X4.1, X3.2 with X4.2 and X3.3 with X.4.3. In the case of that no capacitor disconnect
is required no changes should be made. If capacitor disconnect is required a three-phase contactor should be placed between terminals X3 and X4.
Size the contactor and wiring according to below table. It is recommended only to use contactors with damping resistors.
NB!
It is not allowed to use one common 3 poled contactor in several paralleled AHF at once to disconnect the capacitors.
