Installation
Mount cable glands on the terminal box.
Proceed as follows:
•
Select one cable gland in each case which
is suitable for the cable diameter.
•
Insert this cable gland in the opening of the
terminal box.
Use a reducer if necessary.
•
Screw on the cable gland so that no
moisture, dirt etc. can penetrate into the
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
U
N
≤
690V).
•
For the tightening torques for terminal
board connections (except terminal strips),
see Chapter 3.1, "Mechanical data",
Section "Tightening torques for screw
connections", Pg. 8.
•
For terminals with clamping straps (e.g. as
per DIN 46282), 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 (DIN 46234).
This also applies to:
•
the protective conductor,
•
the outer ground conductor.
Both conductors can be recognized from their
color (green/yellow).
DANGER
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.
DANGER
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 U
N
≤
690V).
There may be no protruding wire ends!
For
motor overload protection
:
•
Use motor circuit breakers.
•
This must be adjusted to the specified
nominal current (see rating plate).
DANGER
Electrical danger!
There is danger of an electrical shock when a
defective pump-motor unit is touched!
Mount motor circuit breaker.
Have electrical equipment checked regularly
by an electrician.
Interference immunity of drive motor:
For drive motors with integrated sensors, the
operator must provide for a sufficient
interference immunity itself. Select a suitable
sensor signal cable (e.g. with screening,
connection as for a motor power-supply cable)
and analyzing unit.
Operation with frequency converter:
With a power supply by external frequency
converters, the following must be observed:
•
High-frequency current and voltage
harmonics in the motor supply cables can
lead to emitted electromagnetic
interference. This is dependent on the
converter design (model, manufacturer,
interference suppression measures).
•
Be sure to observe the EMC notes of the
converter manufacturer!
