Pumps with DC motor (brushed)
1. Compare the supply data with the data on the motor plate. For
maximum operating current of the pump see pump’s type
plate.
The voltage must not vary by more than + 10% and – 10%
from that shown on the type plate.
2. Connect the positive and negative terminals.
Note the proper polarity:
red connection cable: +
black connection cable: -
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 DIN EN 61000-6-1 technical norm for EMC
protection, part 1,10 test demands for EMC protection, table 3,
EMC protection, D.C.- power in- and outputs. Remark 3: (quota-
tion) Not to be used with input connections which are foreseen for
a connection with a battery or a rechargeable battery which has to
be removed 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. pow-
er 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.
Pumps with brushless DC motor
3. Compare the supply data with the data on the motor plate. For
maximum operating current of the pump see pump’s type
plate.
The voltage must not vary by more than + 10% and – 10%
from that shown on the type plate.
4. Connect the positive and negative terminals.
Note the proper polarity:
red connection cable: +
blue connection cable: -
Motors marked with a “K” on the type plate of the motor have
inverse-polarity protection.
