Tecnotion QTR 65 Series Manual page 5

Provide sufficient radial and axial centering and guidance to prevent
collision during installation.
Be sure that the stator and rotor are fixed into your machine before
removing the magnetic field protection plates. The stator and rotor
will attract each other during installation. These forces cannot be
controlled by hand. Put the magnetic field protection plates on again
before dismounting them.
Magnetic sensitive objects like banking cards, pacemakers or other
magnetic information carriers may be damaged if they are brought
within 1 m of the magnets (plates or rotor).
If at any time and in any situation there is any doubt about the safety of
the motor, do not use it and contact your supplier.
Mechanical safety
The motor is used as a part of a machine. The user has to take care that
the machine as a whole fulfils all CE requirements.
The motor is powered by a servo amplifier. In case of a power
disruption or fatal error this may automatically result in a free run out
of the motor. Make mechanical precautions to prevent damage on the
motor or your machine in the case of such an event.
The magnets can detach from the rotor when the motor is operated
above its allowed maximum rotational speed. This can cause personal
injury or damage to the motor and the entire application. This speed
varies per motor type. Please set the correct maximum speed for the
installed torque motor. Refer to appendix G for maximum mechanical
speed.

Earthing
Before installing the motor, make sure that the supply mains are
grounded and operate in conformity with the regulations in force.
Make sure that there is an effective protective earth. Make sure that
there is no voltage at the wire terminals before connecting.
An earth connection does not work on non-conducting mounting
surfaces like granite. In these cases the protective earth must be
established by an earthing wire.
Maintenance
Before carrying out checks or doing any maintenance, clear the system
by disconnecting the voltage. Be sure that there is no possibility of
accidental connections.
The components can be damaged when cleaned with a non-
prescribed cleaning agent. Use only isopropanol as a cleaning agent.
Adhesives and activators can damage the stator and rotor.
UV blacklight can cause irreversible damage to the eyes and other
tissue when exposed. When using a UV blacklight installation wear
appropriate protective clothing and glasses.
The motor contains permanent magnets that produce a magnetic stray
field. For transport safety please check chapter 6 for information on
transport.
