Regulations:
The electrical connection must be carried out
as follows:
 according to the applicable national and
local laws and regulations,
 according to the applicable system-
dependent prescriptions and requirements,
 according to the applicable regulations of
the utility company.
Electrical power supply:
Observe the rating plate.
It is imperative that the operating conditions
correspond to the data given on the rating
plate!
Deviations permissible without reduction in
performance:
 ±5 % voltage deviation
 ±2 % frequency deviation
Connection to drive-motor terminal box:
Carry out the connection and the arrangement
of the jumpers in accordance with the circuit
diagram in the terminal box.
Connect the protective conductor to the
terminal with the following symbol:
The electrical connection must be carried out
as follows:
 The electrical connection must be
permanently safe.
 There may be no protruding wire ends.
 Clearance between bare live parts and
between bare live parts and ground: ≥ 5.5
mm [0.217"] (at a nominal voltage of
UN ≤ 690 V).
 Tightening torques for terminal plate
connections:
see Chapter 3.1, "Mechanical data",
Section "Tightening torques", Pg. 7.
 Use suitable cable lugs.
 For terminals with clamping straps, the
conductors must be inserted so that
approximately the same clamping height
results on both sides of the bar.
Individual conductors must therefore be
bent into a U-shape or connected with a
cable lug.
 All conductors under outer angled
grounding brackets must be bent into a "U"
shape.
This also applies to:
 the protective conductor,
 the outer ground conductor.
Both conductors can be recognized from their
color (green/yellow).
 WARNING
Electrical danger!
Clearance between bare live parts and
between bare live parts and ground:
at least 5.5 mm [0.217"] (at a nominal voltage
of V
n
≤ 690V)
Make sure there are no
protruding pieces of wire!
 WARNING
Electrical danger!
The terminal box must be free from
 foreign
bodies,
 dirt,
 humidity.
Terminal box cover and cable entries must be
tightly closed so as to make them dustproof
and waterproof.
Check for tightness at regular intervals.
For motor overload protection:
 Use motor circuit breakers.
 Set the motor circuit breakers to the
nominal current specified on the rating
plate.
