Danger!
Risk of injury due to electric shock!
There is an immediate risk of fatal injury in case of contact with live parts.
If connections are connected or disconnected in the wrong order or under voltage, arcs can arise and
persons and contacts can be damaged.
Even if the motor is not turning, the control and power connections can still carry voltage!
•
Never touch the connectors when the power is on.
•
Never disconnect or connect electrical connections to the motor and servo drive under voltage!
•
Do not remain in the dangerous zone during operation; secure the danger zone from access
by unauthorized persons.
•
Always operate the motor with all of its safety features. You should also do this during short-
term testing and trial operations!
•
Keep all covers and switch cabinet doors closed during operation and for as long as the ma-
chine has not been disconnected from the mains.
•
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 discharging time of an intermediate circuit, if present.
•
Only connect the measuring instruments in the absence of current and voltage!
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.
•
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 safety precautions need to 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 stop switches to stop
the machine as quickly as possible in the event of an accident.
