You should pay attention to this
l
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.
l
Only properly qualified personnel are permitted to perform such tasks as transport,
assembly, setup and maintenance. Qualified specialist staff are persons who are fa-
miliar with the transport, installation, assembly, commissioning and operation of dri-
ves and who bring their relevant minimum qualifications to bear on their duties:
Transport :
only by personnel with knowledge of handling electrostati-
cally sensitive components.
Mech. Installation : only by mechanically qualified personnel.
Electr. Installation : only by electrically qualified personnel.
Setup
:
only by qualified personnel with extensive knowledge of
electrical engineering and drive technology
l
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).
l
During motor operation, there is a danger of death, severe injury or material dama-
ge. The operator must therefore ensure that all persons entrusted to work on the
motor have read and understood the manual and that the safety notices in this ma-
nual are observed.
l
Lift and move motors with more than 20kg weight only with lifting tools. Lifting unas-
sisted could result in back injury.
High voltages
It is vital that you ensure that the motor housing is safely earthed to the PE(protective
earth) busbar in the switch cabinet. Risk of electric shock. Electrical safety is impossible
without a low-resistance earth connection.
Do not unplug any connectors during operation. There is a risk of death or severe injury
from touching exposed contacts. 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.
After disconnecting the servo amplifier from the supply voltage, wait several minutes
before touching any components which are normally live (e.g. contacts, screw connec-
tions) or opening any connections. The capacitors in the servo amplifier can still carry a
dangerous voltage several minutes after switching off the supply voltages. To be quite
safe, measure the DC-link voltage and wait until the voltage has fallen below 50V.
Hot surface
The surfaces of the motors can be very hot in operation, according to their protection
category. Risk of minor burns!
The surface temperature can exceed 100°C. Measure the temperature, and wait until the
motor has cooled down below 40°C before touching it.
