Safety instructions T 65 digital ULTRA-TURRAX ®
• When changing over the dispersing element, switch the unit
off at the main switch.
• Make certain that the unit is set at the lowest speed before
commissioning; otherwise, the unit will begin running at the
speed last set. Gradually increase the speed.
• Reduce the speed if the medium splashes out of the vessel
because the speed is too high.
• Hazards due to frequency inverters
The control unit of the T 65 digital ULTRA-TUR-
RAX ® includes a frequency inverter. This poses the
hazard that potentially fatal voltages may persist
within the unit and at its terminals for up to five
minutes after it was switched off.
It can also be the case that when the equipment
is connected to the mains but its motor is not tur-
ning, hazardous voltages may exist at the terminals
and at the supply leads to the motor.
• Hazards due to high levels of earth leakage currents
The control unit of the T 65 digital ULTRA-TUR-
RAX ® employs a frequency inverter and an EMC fil-
ter. This poses the hazard that high values of earth
leakage currents (> 3.5 mA) may arise.
In addition to the earth lead in the mains power
cable, the equipment must be provided with an
additional earth continuity conductor of at least 10
mm
2 cross-section.
• The motor and the frequency inverter are disconnected from
the power supply by switching off at the EMERGENCY STOP
switch (main switch).
• Before connecting the control unit or the stand li-
mit switch you must make sure that no voltage is
present.
Connection may be performed only by authorised
persons.
• Working on electrical equipment: When the po-
wer supply is connected, high voltages are present
on the equipment. These high voltages can have fa-
tal effects if touched. Work may be performed only
by authorised persons. The applicable regulations
must be complied with.
• Hazards due to the machine: The machine itself
poses hazards for the user and the user must take
appropriate precautions. The control unit has the
capability to link in the limit switches. See "T 65 ba-
sic/ T 65 digital ULTRA-TURRAX ® circuit diagram".
• Additional protection is provided by use of an RCD (resi-
dual current circuit breaker) at the connection for the T 65
digital ULTRA-TURRAX ® .
Additional protection is provided by use of an RCD protective
device: RCD relay residual current circuit breakers can provide
additional protection provided the local safety regulations are
complied with. If there are faults to earth, DC elements can
arise in the fault current. Never use an RCD type A, since these
are unsuitable for fault currents that have a DC element.
If RCD relays are used, they must be suitable for:
- the protection of installations with a DC element in the fault
current (three-phase bridge rectifiers),
- short-term discharge of impulse current peaks at switching on,
- high earth leakage currents.
For protection of the equipment
• The appliance may only be opened by experts.
• The voltage stated on the type plate must correspond to the
mains voltage.
• Removable parts must be refitted to the appliance to prevent
the infiltration of foreign objects, liquids etc..
• Protect the appliance and accessories from bumps and impacts.
