Fundamental safety instructions 1
1.1 General safety instructions
DANGER
Danger to life due to live parts and other energy sources
Death or serious injury can result when live parts are touched.
● Only work on electrical devices when you are qualified for this job.
● Always observe the country-specific safety rules.
Generally, six steps apply when establishing safety:
1. Prepare for shutdown and notify all those who will be affected by the procedure.
2. Disconnect the machine from the supply.
– Switch off the machine.
– Wait until the discharge time specified on the warning labels has elapsed.
– Check that it really is in a no-voltage condition, from phase conductor to phase
conductor and phase conductor to protective conductor.
– Check whether the existing auxiliary supply circuits are de-energized.
– Ensure that the motors cannot move.
3. Identify all other dangerous energy sources, e.g. compressed air, hydraulic systems, or
water.
4. Isolate or neutralize all hazardous energy sources by closing switches, grounding or short-
circuiting or closing valves, for example.
5. Secure the energy sources against switching on again.
6. Ensure that the correct machine is completely interlocked.
After you have completed the work, restore the operational readiness in the inverse sequence.
WARNING
Danger to life through a hazardous voltage when connecting an unsuitable power supply
Touching live components can result in death or severe injury.
● Only use power supplies that provide SELV (Safety Extra Low Voltage) or PELV-
(Protective Extra Low Voltage) output voltages for all connections and terminals of the
electronics modules.
PPU and components
Manual, 10/2015, 6FC5397-2DP40-5BA3 9

WARNING
Danger to life when live parts are touched on damaged devices
Improper handling of devices can cause damage.
For damaged devices, hazardous voltages can be present at the enclosure or at exposed
components; if touched, this can result in death or severe injury.
● Ensure compliance with the limit values specified in the technical data during transport,
storage and operation.
● Do not use any damaged devices.
WARNING
Danger to life through electric shock due to unconnected cable shields
Hazardous touch voltages can occur through capacitive cross-coupling due to unconnected
cable shields.
● As a minimum, connect cable shields and the cores of cables that are not used at one end
at the grounded housing potential.
WARNING
Danger to life due to electric shock when not grounded
For missing or incorrectly implemented protective conductor connection for devices with
protection class I, high voltages can be present at open, exposed parts, which when touched,
can result in death or severe injury.
● Ground the device in compliance with the applicable regulations.
WARNING
Danger to life due to fire spreading if housing is inadequate
Fire and smoke development can cause severe personal injury or material damage.
● Install devices without a protective housing in a metal control cabinet (or protect the device
by another equivalent measure) in such a way that contact with fire is prevented.
● Ensure that smoke can only escape via controlled and monitored paths.

WARNING
Danger to life due to fire if overheating occurs because of insufficient ventilation clearances
Inadequate ventilation clearances can cause overheating of components with subsequent
fire and smoke. This can cause severe injury or even death. This can also result in increased
downtime and reduced service lives for devices/systems.
● Ensure compliance with the specified minimum clearance as ventilation clearance for the
respective component.
WARNING
Danger to life when safety functions are inactive
Safety functions that are inactive or that have not been adjusted accordingly can cause
operational faults on machines that could lead to serious injury or death.
● Observe the information in the appropriate product documentation before commissioning.
● Carry out a safety inspection for functions relevant to safety on the entire system, including
all safety-related components.
● Ensure that the safety functions used in your drives and automation tasks are adjusted
and activated through appropriate parameterizing.
● Perform a function test.
● Only put your plant into live operation once you have guaranteed that the functions relevant
to safety are running correctly.

1.4 Residual risks of power drive systems
The control and drive components of a drive system are approved for industrial and commercial
use in industrial line supplies. Their use in public line supplies requires a different configuration
and/or additional measures.
These components may only be operated in closed housings or in higher-level control cabinets
with protective covers that are closed, and when all of the protective devices are used.
These components may only be handled by qualified and trained technical personnel who are
knowledgeable and observe all of the safety instructions on the components and in the
associated technical user documentation.
When assessing the machine's risk in accordance with the respective local regulations (e.g.,
EC Machinery Directive), the machine manufacturer must take into account the following
residual risks emanating from the control and drive components of a drive system:
1. Unintentional movements of driven machine components during commissioning, operation,
maintenance, and repairs caused by, for example,
– Hardware and/or software errors in the sensors, control system, actuators, and cables
and connections
– Response times of the control system and of the drive
– Operation and/or environmental conditions outside the specification
– Condensation/conductive contamination
– Parameterization, programming, cabling, and installation errors
– Use of wireless devices/mobile phones in the immediate vicinity of the control system
– External influences/damage
2. In the event of a fault, exceptionally high temperatures, including an open fire, as well as
emissions of light, noise, particles, gases, etc. can occur inside and outside the inverter,
e.g.:
– Component failure
– Software errors
– Operation and/or environmental conditions outside the specification
– External influences/damage
Inverters of the Open Type/IP20 degree of protection must be installed in a metal control
cabinet (or protected by another equivalent measure) such that contact with fire inside and
outside the inverter is not possible.
3. Hazardous shock voltages caused by, for example,
– Component failure
– Influence during electrostatic charging
– Induction of voltages in moving motors
– Operation and/or environmental conditions outside the specification
– Condensation/conductive contamination
– External influences/damage
Fundamental safety instructions
1.4 Residual risks of power drive systems
PPU and components
14 Manual, 10/2015, 6FC5397-2DP40-5BA3

4. Electrical, magnetic and electromagnetic fields generated in operation that can pose a risk
to people with a pacemaker, implants or metal replacement joints, etc., if they are too close
5. Release of environmental pollutants or emissions as a result of improper operation of the
system and/or failure to dispose of components safely and correctly
Note
The components must be protected against conductive contamination (e.g. by installing them
in a control cabinet with degree of protection IP54 according to IEC 60529 or NEMA 12).
Assuming that conductive contamination at the installation site can definitely be excluded, a
lower degree of cabinet protection may be permitted.
For more information about residual risks of the components in a drive system, see the relevant
sections in the technical user documentation.

Note
Additional axes for the PPU 28x.3
Using a NX10.3, the following extensions are possible:
● The maximum number of axes can be increased to eight, six of which can be connected
to the PPU and two to the NX10.3.
● One high-speed spindle (e.g. 24,000 rpm with four pole pairs) can be connected to the
NX10.3 and five axes to the PPU.
Using an NX15.3, the following extensions are possible:
● The maximum number of axes can be increased to 10, of which 6 axes can be connected
to the PPU and 4 axes to the NX15.3.
