size. Danfoss offers a wide variety of different resistors that
are specially designed to our frequency converters. See
2.13 Control with Brake Function for the dimensioning of
brake resistors. Code numbers can be found in 4 How to
Order.

3.6.12 Remote Mounting Kit for LCP

The LCP can be moved to the front of a cabinet by using
the remote built-in kit. The enclosure is IP66. The fastening
screws must be tightened with a torque of max. 1 Nm.

3.6.13 Input Filters

The 6-pulse diode rectifier causes the harmonic current
distortion. The harmonic currents affect the installed serial
equipment identical to reactive currents. Consequently,
harmonic current distortion can result in overheating of
the supply transformer, cables and so on. Depending on
the impedance of the power grid, harmonic current
distortion can lead to voltage distortion also affecting
other equipment powered by the same transformer.
Voltage distortion is increasing losses, causes premature
aging and worst of all erratic operation. The built-in DC
coil reduces most harmonics, but if more reduction is
needed, Danfoss offers two types of passive filters.
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 the Danfoss frequency converters.
AHF 010 is reducing the harmonic currents to less than
10% and the AHF 005 is reducing harmonic currents to
less than 5% at 2% background distortion and 2%
imbalance.

3.6.14 Output Filters

The high-speed switching of the frequency converter
produces some secondary effects, which influence the
motor and the enclosed environment. Two different filter
types, the dU/dt and the Sine-wave filters, are in place to
address these side effects.
