NPK 25 DC
Connect the positive and negative pole.
With DC motors, note the proper polarity:
red motor cable: +
black motor cable: -
3.
Connect the earth (ground) wire to the motor (not necessary
on dc motors up to 24 V).
EMC-compatible Installation (for NPK 25 DC)
The Tests:
- Magnetic field with energy-technical frequency
- Electromagnetic HF field, amplitude-modulated
- Electromagnetic HF field, pulse-modulated
- Discharging of static electricity
- High frequency, asymmetric
- Fast transients
were not carried out, cause the products do not contain electronic
modules, which can be affected by these tests.
The Surge-test can only be passed with additional means, or is not
mandatory, if: From EN61000-6-1 technical norm for EMC protec-
tion, part 1,10 test demands for EMC protection, table 3, EMC
protection, D.C.- power in- and outputs. Remark 3: (quotation) Not
to be used with input connections which are foreseen for a connec-
tion with a battery or a rechargeable battery which has to be re-
moved or disconnected from the device for the recharge.
Devices with a D.C. power input which are foreseen to be operated
with an A.C. / D.C. converter have to be tested at an A.C. power
input of an A.C. / D.C. converter fixed by the manufacturer. In case
the converter was not fixed they have to be tested at an A.C.
power input of a typical (usual) A.C. / D.C. converter.
The test is applicable for D C power inputs which are foreseen for
a permanent connection to cables which are longer than 10 m.
