NOTE
The NEMA 1 cover is designed for the mounting of Danfoss
contactors.
When using non Danfoss contactors, please observe the
dimensions of the NEMA 1 terminal cover and ensure that
there is space for the contactor.

< h < 2000m = 5% per 1000m
NOTE
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 observed.
