2.4.2 Safety notes for assembly and maintenance
In terms of the assembly and maintenance of the system, the corresponding DIN, VDE, EN, and IEC regulations as well as all of
the national and local safety regulations and rules for the prevention of accidents apply. The system manufacturer or operator
is responsible for ensuring compliance with these regulations:
Only personnel who have been trained and qualified for working on or with electrical devices are authorised to
operate, maintain, and/or repair the servo positioning controller.
Prevention of accidents, injuries, and/or damage to property:
Vertical axes must be additionally secured against falling down or lowering after the motor has been switched
off, for example by way of the following:

mechanical locking of the vertical axis,

external braking, catching, or clamping devices, or

sufficient weight counterbalance of the axis.
The standard motor holding brake that is included in the scope of supply or any other external motor holding
brake that is actuated by the drive controller is not suitable for the protection of the operators if used alone!
Disconnect the electrical equipment from the power supply by way of the main switch and secure it so that it
cannot be reconnected. Then, wait until the DC bus circuit has discharged prior to any of the following:

maintenance and repairs

cleaning

long downtimes
Prior to performing any maintenance tasks, ensure that the power supply has been turned off and locked and
that the DC bus circuit has been discharged.
The external or internal braking resistor carries dangerous DC bus circuit voltages during the operation of the
servo positioning controller and up to 5 minutes thereafter. Wait until this time is over prior to performing any
work on the affected connections. Measure the voltages for your own protection. Contact with these high DC
bus circuit voltages may result in death or serious personal injury.
Be careful during the assembly. During the assembly and also later on during the operation of the drive,
ensure that no drilling chips, metal dust, or installation parts (screws, nuts, cable sections) can fall into the
into the servo positioning controller.
Ensure also that the external power supply of the controller (24 V) is switched off.
The DC bus circuit or the mains voltage must always be switched off prior to switching off the 24 V controller
supply.
Ensure that the AC or DC power supplies are switched off and locked prior to performing any work in the area
of the machine. Deactivated output stages or deactivated controller enable signals are no suitable means of
