Danger!
Risk of injury due to electric shock!
If live parts are touched, there is immediate danger of fatal electric shock.
If connections are connected or disconnected in the wrong order or when the power is switched on,
electric arcs can occur and persons and contacts can be damaged.
Even if the motor is not rotating or is running as a generator driven externally, the control and power
connections can still carry voltage!
•
Never touch connections when the power is switched on.
•
Never disconnect or connect electrical connections to the motor and servo drive when the
power is switched on!
•
Do not stay in the danger zone during operation and secure it against access by unauthorized
persons.
•
Always operate the motor with all safety equipment. Do this even during short testing and trial
operations!
•
Keep all covers and control cabinet doors closed during operation and as long as the machine
is not disconnected from the power system.
•
Before working on motors, gearboxes or servo drives or in the danger zone of your machine,
disconnect them completely from the power system and secure them against being switched
on again by other persons or automatic systems.
•
Note the discharge time of any existing DC bus.
•
Only connect measuring instruments when the power is switched off!
Danger due to electromagnetic fields
Electromagnetic fields are generated by the operation of electrical power engineering equipment such as trans-
formers, drives and motors.
Danger!
Danger to health due to electromagnetic fields!
The functionality of a heart pacemaker can be impaired by electromagnetic fields to such an extent
that the wearer experiences harm to his or her health, possibly with a fatal outcome.
•
Observe relevant national health and safety regulations.
•
Persons with pacemakers are not allowed to be in endangered areas.
•
Warn staff by providing information, warnings and safety identification.
•
Secure the danger zone by means of barriers.
•
Reduce electromagnetic fields at their source (using shielding, for example).
Dangerous motion
By rotating and positioning motions of the motors, machine elements are moved or driven and loads conveyed.
After switching on the machine, movements of the motor shaft must always be expected! For this reason, high-
er-level protective measures must be put in place to ensure that personnel and machines are protected. This type
of protection can be achieved, for example, by using stable mechanical protective equipment such as protective
covers, protective fences, protective gates or photoelectric sensors.
In the immediate vicinity of the machine, provide sufficient and easily accessible emergency switching-off devices
to stop the machine as quickly as possible in the event of an accident.
