Electrical connection

Circuitry for high voltage (29713)
Alterations to the circuitry are to be made using
crimp connectors (X). The new crimp connec-
tion must be professionally made.
By using our controls, you can be sure that the
D E F
requirements of the EU type-testing certificate
are met.
The standards applicable in each case (e.g. EN),
the country-specific regulations (e.g. VDE in
Germany), and the regulations of the local sup-
ply network operator must be observed.
ATTENTION! Never lay the end of cables in wa-
ter! Penetrating water may cause malfunctions.
Only slow-blow fuses or automatic fuses with C
or D characteristics are to be used as pre-fuses
for the pump. Necessary fuse protection for for
star-delta start 16 A for pumps 55..., 20 A for
pumps 75... and 25 A for pumps100...
The pump must be protected via an overload
trip. Setting for direct on-line start = nominal
current, and for star-delta start = nominal cur-
rent x 0.58.
If the protective device has been triggered, the
cause of the malfunction must be eliminated
before switching on again.
Potential equalisation
To comply with EN 60079-14 and EN 1127-1, an
additional equipotential bonding must be in-
stalled for facilities with protective earth con-
ductors in TN/TT networks in areas subject to
explosion hazards. In Germany, for example,
the design must be in accordance with VDE
0100, Part 540 (Association of German Electri-
cal Engineers).
No additional potential equalisation is required
on site for JUNG PUMPEN concrete or plastic
chambers in explosion zones 1 and 2 (state-
ment made by TÜV Nord (Technical Inspection
Agency) in March 2008).
Exception: if conductive parts, such as cable
protection sleeves made of corrugated pipe or
a pressure pipe made of metal, are connected
to the chamber from the outside. In this case,
Only qualified electricians may carry
out electrical works to the pump or
the controls.
an electrically conductive connection must be
made between the conductive parts and the
housing of the pump(s). For corrosion protec-
tion reasons, the connection should be made
using stainless steel.
Explosion protected pumps (UFK...) have a spe-
cial connection point at the cable entry point.
Rotational direction
The rotational direction must be checked be-
fore installation! If the rotational direction is
correct, the start-up jolt should be in the oppo-
site direction to the rotational direction arrow
on the motor housing. The wrong rotational
direction is also indicated if the pump performs
inadequately when installed, or if loud noises
can be heard during operation. If the rotational
direction is wrong, 2 phases of the supply cable
must be swapped over.
The start-up jolt can be very forceful.
Coil thermostats
ATTENTION! In addition to the overload trip or
protective switch of the motor, the thermostats
integrated in the motor winding must also be
connected. The thermostats are suitable for
250 V / 1.2 A (cos phi = 0.6) and are labelled 30
and 32 for connection purposes.
Thermostat connection without explosion
protection (UAK)
The thermostats are to be connected in such a
way that the motor is switched off via the con-
trol circuit when the response temperature is
reached. The motor is switched on again auto-
matically after the winding has cooled down.
Thermostat connection with explosion
protection (UFK)
The thermostats are to be connected in such
a way that the motor is switched off via the
control circuit when the response temperature
is reached. It must not be possible for the mo-
tor to switch on again automatically after the
winding has cooled down.
After an automatic cut-out via the
temperature limiters, the cause of
the malfunction must first be elimi-
nated. Only then may the motor be switched
on again manually.
The restart interlock must be "non-resetting on
power failure", i.e. the lock must be in place to
prevent restarting even after a power cut (in
Europe: Directive 94/9/EC, Appendix II 1.5, EN
60079-17 Table1, B10).
Operation with frequency converter
Frequency converters may only be used for
controlling the frequency of special models of
three-phase pumps.
ATTENTION! For physical reasons, pumps may
not be operated at a higher frequency than
