4.5 Electrical connection
Consult the motor's rating plate for the
electrical characteristics of the motor.
Observe the guidelines in EN 60034-1
(VDE 0530-1) for operation at the limits of
the ranges A (combination of ±5% voltage
deviation and ±2% frequency deviation) and
B (combination of ±10% voltage deviati-
on and +3/-5% frequency deviation). This
applies especially with regard to deviations
in operating parameters from the ratings on
the motor's rating plate.
The limits must never be exceeded.
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 EC / EN 60204-1).
Details regarding electrical connection of the
motor to the power supply, especially terminal
and connector pin assignment, can be taken
from the following motor data table or
customer's drawing (if available).
When establishing the gear pump unit’s
electrical connection, ensure that appropriate
measures prevent interference between sig-
nals due to inductive, capacitive, or electro-
magnetic couplings.
Shielded cables must be used if electrical in-
terference fields affect signal transmissions
despite separate laying of cables. Ensure
that cables are arranged in an “EMC-com-
pliant” manner.

WARNING
Electric shock
Electrical connections for the
product may only be established
by qualified and trained personnel
authorized to do so by the operator.
The local electrical operating con-
ditions and local regulations (e.g.,
DIN, VDE) must be observed.
