Safety Instructions
lThe strong magnetic fields which are produced constitute a hazard for persons with
implants, such as cardiac pacemakers, that can be influenced by magnetic fields. As
a general rule, all persons who may suffer impairment to health through the
influence of strong magnetic fields must keep at a safe distance of at least 1 meter
from the motor.
lAlways wear gloves when working on the linear motor. During work on or in the
vicinity of linear motors make sure that at least two finely pointed wedges of tough
non-magnetic material - e.g. V2A - (with a wedge angle of approx. 10°-15°) and a
hammer (approx. 3 kg) are to hand. In an emergency you can then use these tools to
detach objects that are magnetically bound to the magnet track (for instance, to free
trapped parts of the body).
lBecause of the high forces of attraction, special care must be taken within a range of
about 50 mm from the magnet track. Inside this area, heavy (>1kg) or large-area
(>1dm²) objects of steel or iron must not be held in the hand.
lKeep watches and magnetic data media (credit cards, diskettes, etc.) out of the
immediate vicinity (<100 mm) of the linear motor.
lOnly properly qualified persons are permitted to perform activities such as transport,
installation, commissioning and maintenance. Properly qualified persons are those
who are familiar with the transport, assembly, installation, commissioning and
operation of motors, and who have the appropriate qualifications for their job.
Qualifed personnel must know and observe the following standards and directives:
IEC 364 and/or CENELEC HD 384 or DIN VDE 0100
IEC Report 664 or DIN VDE 0110
national accident prevention regulations, or BGV A2
lRead the available documentation before installation and commissioning. Incorrect
handling of the motor can cause injury and damage to persons and equipment.
lIt is mandatory to ensure that the magnet track is properly grounded to the PE
(protective earth) busbar in the switchgear cabinet. Safety for personnel cannot be
assured without a low-resistance protective earth.
lNever pull out a connector during operation. This creates a hazard with the risk of
death, severe injury, or material damage.
lPower connections may still be live, even though the motor is not moving. Never
undo the electrical connections to the motor while a voltage is present. In
unfavorable cases this can cause arcing, with injury and damage to persons and
equipment.
lAfter disconnecting the servo amplifier from the supply power, wait at least five
minutes before touching live parts (such as contacts or studs) or breaking
connections. To be sure, measure the voltage in the DC-link circuit and wait until it
has fallen below 40V.
lDuring operation, motors can have very hot surfaces, depending on their enclosure
rating. Surface temperatures can reach 100°C. Measure the temperature, and wait
until the motor has cooled down to below 40°C before touching it.
