Safety instructions for assembly and maintenance

For assembling and maintaining the system, the relevant DIN,
VDE, EN and IEC regulations as well as all national and local safety and accident
prevention regulations must always be observed. The system manufacturer or the user is
responsible for ensuring that these regulations are observed.

Warning

The motor controller may only be operated, maintained and/or
serviced by persons qualified and trained to work on or with
electrical devices.


Avoiding accidents, bodily injury and/or material damage:

Warning

The series-supplied motor holding brake or an external motor-
holding brake controlled by the drive controller alone is not
suitable for protecting human beings.

Vertical axes must be additionally secured against falling or
sliding down when the motor is switched off with, for example,
- mechanical locking of the vertical axis,
- external braking, safety catch or clamping devices or
- sufficient weight compensation of the axis.

Warning

The internal brake resistance can cause dangerous intermediate
circuit voltage during operation and up to several minutes after the
motor controller is switched off. If touched, this can lead to fatal or
serious injuries.

Before carrying out maintenance work, make sure that the
power supply is switched off and locked and that the
intermediate circuit is discharged.

Switch off power to the electrical equipment and secure it
against being switched on again. Wait until the intermediate
circuit is discharged in the case of:
- maintenance and repair
- cleaning
- long service interruptions.

Warning

Proceed carefully with mounting. Make sure that , during mounting
as well as later during the operation of the drive, no drilling
shavings, metal dust or mounting parts (screws, nuts, pieces of
wire) can fall into the motor controller.

Ensure that the external power supply of the controller (mains
voltage 230 V) is switched off.
