Safety Notes
l
Only properly qualified personnel are permitted to perform such tasks as transport,
assembly, commissioning and maintenance. Properly qualified personnel are
persons who are familiar with the transport, assembly, installation, commissioning
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 364 resp. CENELEC HD 384 or DIN VDE 0100
IEC-report 664 or DIN VDE 0110
national regulations for safety and accident prevention or BGV A2
l
Read the available documentation before assembly and commissioning. 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).
l
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-resistance earth connection.
l
Do not unplug any connectors during operation. This creates the danger of death,
severe injury, or extensive material damage.
l
Power connections may be live even when the motor is not rotating. Never
disconnect 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.
l
After disconnecting the servoamplifier from the supply voltage, wait at least five
minutes before touching any components which are normally live (e.g. contacts,
screw connections) or opening any connections.
The capacitors in the servoamplifier can still carry a dangerous voltage up to five
minutes after switching off the supply voltages. To be quite safe, measure the
DC-link voltage and wait until the voltage has fallen below 40V.
l
The surfaces of the motors can be very hot in operation, according to their
protection category. The surface temperature can reach 100°C. Measure the
temperature, and wait until the motor has cooled down below 40°C before touching
it.
