4.3 Electrical motor connection
Electric shock hazard
Electrical connections for the product
may only be established by qualified
and trained personnel authorized to do
so by the operator.
The local conditions for connections and local
regulations (e.g., DIN, VDE) must be observed.
Significant bodily injury and property damage
may result from improperly connected
products.
Warning!
Connect lines in accordance with the
technical specifications and the local
conditions for connections and local
regulations (e.g., DIN, VDE).
Consult the motor's rating plate for the electrical
characteristics of the motor, such as rated power,
rated voltage, and rated current. Observe the
guidelines in EN 60034-1 (VDE 0530-1) for
operation at the limits of the ranges A (combi-
nation of ±5% voltage deviation and ±2%
frequency deviation) and B (combination of
±10% voltage deviation and +3/-5% frequency
deviation). This applies especially with regard
to heating and deviations in operating param-
eters from the ratings on the motor's name-
plate. The limits must never be exceeded.
Warning!
The available mains voltage (supply
voltage) must be in accordance with the
specifications on the rating plate of the
motor or of the electrical components.
Check the fuse protection of the electrical circuit.
Use only fuses with the prescribed amperage,
else bodily injury and property damage may
result.
Be sure to connect the motor so as to guarantee
a continuously safe electrical connection (no
protruding wire ends); use the assigned cable
end fittings (e.g. cable lugs, wire end ferrules).
Select connecting cables conforming to DIN
VDE 0100 taking into account the rated current
and the conditions of the specific system (e.g.
ambient temperature, type of routing etc. in
accordance with DIN VDE 0298 or IEC / EN
60204-1). Details regarding electrical connec-
tion of the motor to the power supply, especially
terminal and connector pin assignment, can
be taken from the customer's drawing for the
reservoir unit.
Warning!
When establishing electrical connection
of the pump motor, be mindful of the
correct direction of rotation of the
motor.
If the direction of rotation of a motor is
marked on the product by a rotation arrow,
the motor's direction of rotation must match
the arrow.
Connect the pump unit motor according to
the specifications on the motor rating plate
and the motor characteristics.
