Perform a risk assessment!
The manufacturer of the machine must create a risk analysis for the machine and take appro-
priate measures to ensure that unexpected movements cannot cause any injury or damage
to any person or property.
Specialist staff required!
Only thoroughly qualified persons are permitted to perform activities such as transport, instal-
lation, commissioning and maintenance. Thoroughly qualified persons are those who are
familiar with the transport, assembly, installation, commissioning and operation of linear
motors, and who have the appropriate qualifications for their job.
l
Transport: only by staff with knowledge of handling electrostatically sensitive com-
ponents and magnetic materials.
l
Mechanical Installation: only by mechanically qualified staff.
l
Electrical Installation: only by electrically qualified staff.
l
Setup: only by qualified staff with extensive knowledge of electrical engineering and drive
technology
Qualified staff must know and respect the following standards and directives:
IEC 60364 or IEC 60664 or national accident prevention regulations
Hot surface!
The surfaces of the motors can be very hot during operation, according to their protection cat-
egory. Risk of minor burns! The surface temperature can exceed 100°C. Measure the tem-
perature and wait until the motor has cooled down below 40°C before touching it.
Earthing! High voltages!
It is mandatory to ensure that all metallic motor parts are safely grounded to the PE (pro-
tective earth) terminal in the switchboard. Electrical safety is not possible without low-resist-
ance protective earth connection. Safety of personnel cannot be assured without protective
earth connection.
Never unplug any connector during operation. This creates a hazard with the risk of death,
severe injury or material damage.
Power connections may still be live, even though the motor is not moving. Never disconnect
the electrical connections to the motor while a voltage is present. This can cause flashover
with injury and damage to persons and equipment.
After disconnecting the drive from the supply power, wait at least five minutes before touch-
ing any components which are normally live (e.g. contacts, screw connections) or opening
any connections. The capacitors in the drive can still carry a dangerous voltage up to five min-
utes after switching off the supply voltages. To ensure safety, measure the voltage in the
DC-link circuit and wait until it has fallen below 40V.
Strong magnets!
During the 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. material V2A with a wedge angle of approx.
10°-15°) and a hammer (approx. 3 kg) are at hand. In an emergency case you can use these
tools to detach objects that are magnetically bound to the magnetic track (e.g. to free trapped
parts of the body).
Keep watches and magnetic data media (credit cards, diskettes, etc.) out of the immediate
vicinity (<50cm) of the linear motor.
Place easily visible warning signs (e.g. permanent self-adhesive labels) on the machine:
Caution: The linear motors on this machine are fitted with strong permanent magnets.
