Connection may be performed only by authorised persons. The
applicable regulations must be complied with.
Electrical connection (for this see the circuit diagram for the
T 65 basic/digital ULTRA-TURRAX ® ):
The control unit must be connected first to the machine and
then to the power supply.
The electrical connection to the power supply must be in ac-
cordance with the details listed on the circuit diagram regarding
nominal voltage, nominal frequency, nominal current and maxi-
mum fuse rating.
The connection arrangement can be seen on the circuit diagram
supplied.
After the power supply has been connected the unit is ready for
operation.
The EMERGENCY STOP switch supplied by the customer is ins-
talled between the mains power cable and the terminal box on
the unit.
Motor protection T 65 basic ULTRA-TURRAX ®
The AC motor runs in ball bearings and is maintenance-free. In its
attached control cabinet, it has a special safety device for opera-
tion on overcurrent and undervoltage (undervoltage trip), to per-
manently switch the motor off and avoid any thermal damage.
The unit can only be put back in service when the power supply
required for the motor is restored.
The basic connection and performance data for the motor can
be obtained from the motor rating plate.
Motor protection T 65 digital ULTRA-TURRAX ®
The three-phase motor with integral frequency inverter is main-
tenance-free and is protected against overcurrent and overtem-
perature. Any fault arising is shown on the display; see the sec-
tion "Error codes". The T 65 digital ULTRA-TURRAX
® switches
itself on again automatically once the fault has been cleared.
The basic connection and performance data for the motor can
be obtained from the motor rating plate.
Safety disconnection device
If the telescopic stand is moved upwards when the unit
is operating, the dispersion unit must switch off. To faci-
litate this, the telescopic stand must be equipped with a
safety disconnection device.
For this purpose, we recommend the installation of the SI 400 sa-
fety limit switch together with the SI 400 mounting support (see
"Accessories").
The wiring of the SI 400 safety limit switch is connected in the
terminal box of the T 65 basic/digital ULTRATURRAX
® (see cir-
cuit diagram T 65 basic/digital ULTRATURRAX ® ).
Set-up and commissioning
ATTENTION!
Assembly and electrical installation
Telescopic stand T 653
For operation, the dispersion unit must be attached to the IKA
®
T 653 telescopic stand or other stand approved for this unit.
In conjunction with the IKA
® T 653 telescopic stand, the T 65 D
dispersion unit can also be used for tall mixing vessels.
For information on this product, please refer to the operating
instruction "Telescopic stands".
As shown in the diagram, the dispersion unit is mounted on the T
653 telescopic stand with two M12 hexagon socket head (Allen)
(G) screws and toothed lock washers. The screws and toothed
lock washers are included in the delivery package of the stand.
Installation of the unit requires an assistant, and the use of a 10
AF hexagon L-wrench to DIN 912.
Assembly Telescopic stand
The telescopic stand must be installed such that
it does not tilt or slide about. It must not move
about when the unit is operating.
Particular danger points, such as crushing/trapping posi-
tions, rotating parts, locking screws for the stand column,
are identified by an exclamation mark in the “Dispersion
unit assembly” diagram. Particular regard should be paid to
these danger points when the unit is in service!
Elektrical installation
The electrical connections of the dispersion unit must be made
by a skilled worker in accordance with the wiring dia-
gram (see “Wiring diagram”).
Before connecting the control unit, you must make sure that no
voltage is present.
