Only properly qualified personnel are permitted to perform such tasks as transport,
assembly, setup and maintenance. Properly qualified personnel are persons who are
familiar with the transport, assembly, installation, setup and operation of motors, and
who have the appropriate qualifications for their jobs. The qualified personnel must
know and observe the following standards and regulations:
IEC 60364 or DIN VDE 0100
IEC 60664 or DIN VDE 0110
national regulations for safety / accident prevention or BGV A3
Read the available documentation before assembly and setup. Incorrect handling of
the motors can result in injury and damage to persons and machinery. Keep strictly
to the technical data and the information on the connection requirements (nameplate
and documentation).
The manufacturer of the machine must generate a hazard analysis for the machine,
and take appropriate measures to ensure that unforeseen movements cannot cause
injury or damage to any person or property.
It is vital that you ensure that the motor housing is safely earthed to the PE(protective
earth) busbar in the switch cabinet. Electrical safety is impossible without a low-re-
sistance earth connection.
Do not unplug any connectors during operation. This creates the danger of death, se-
vere injury, or extensive material damage.
Power connections may be live even when the motor is not rotating. Never discon-
nect the power connections of the motor while the equipment is energised. This can
cause flashovers with resulting injuries to persons and damage to the contacts.
After disconnecting the servo amplifier from the supply voltage, wait at least five mi-
nutes before touching any components which are normally live (e.g. contacts, screw
connections) or opening any connections.
The capacitors in the servo amplifier can still carry a dangerous voltage up to five mi-
nutes after switching off the supply voltages. To be quite safe, measure the DC-link
voltage and wait until the voltage has fallen below 40V.
The surfaces of the motors can be very hot in operation, according to their protection
category. The surface temperature can exceed 100°C. Measure the temperature, and
wait until the motor has cooled down below 40°C before touching it.
Remove any fitted key (if present) from the shaft before letting the motor run indepen-
dently, to avoid the dangerous results of the key being thrown out by centrifugal for-
ces.
