Fundamental safety instructions 2
2.1 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.
PM240P-2 Power Modules
Hardware Installation Manual, 11/2016, A5E37800827C AB 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 conductors of power cables that are not
used (e.g. brake cores) 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 electric shock when opening plug connections in operation
When opening plug connections in operation, arcs can result in severe injury or death.
● Only open plug connections when the equipment is in a no-voltage state, unless it has
been explicitly stated that they can be opened in operation.
WARNING
Danger to life through electric shock due to the residual charge of the power component
capacitors
Because of the capacitors, a hazardous voltage is present for up to 5 minutes after the power
supply has been switched off. Contact with live parts can result in death or serious injury.
● Wait for 5 minutes before you check that the unit really is in a no-voltage condition and
start work.

10 Hardware Installation Manual, 11/2016, A5E37800827C AB

NOTICE
Material damage due to loose power connections
Insufficient tightening torques or vibrations can result in loose electrical connections. This can
result in damage due to fire, device defects or malfunctions.
● Tighten all power connections with the specified tightening torques, e.g. line supply
connection, motor connection, DC link connections.
● Check all power connections at regular intervals. This applies in particular after transport.
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 from electromagnetic fields
Electromagnetic fields (EMF) are generated by the operation of electrical power equipment,
such as transformers, converters, or motors.
People with pacemakers or implants are at particular risk in the immediate vicinity of this
equipment.
● If you have a heart pacemaker or implant, maintain a minimum distance of 2 m from
electrical power equipment.
WARNING
Danger to life through unexpected movement of machines when using mobile wireless
devices or mobile phones
Using mobile wireless devices or mobile phones with a transmit power > 1 W closer than
approx. 2 m to the components may cause the devices to malfunction, influence the functional
safety of machines therefore putting people at risk or causing material damage.
● Switch the wireless devices or mobile phones off in the immediate vicinity of the
components.

PM240P-2 Power Modules
Hardware Installation Manual, 11/2016, A5E37800827C AB 11

WARNING
Danger to life due to the motor catching fire in the event of insulation overload
There is higher stress on the motor insulation through a ground fault in an IT system. If the
insulation fails, it is possible that death or severe injury can occur as a result of smoke and
fire.
● Use a monitoring device that signals an insulation fault.
● Correct the fault as quickly as possible so the motor insulation is not overloaded.
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 of an accident occurring due to missing or illegible warning labels
Missing or illegible warning labels can result in accidents involving death or serious injury.
● Check that the warning labels are complete based on the documentation.
● Attach any missing warning labels to the components, in the national language if
necessary.
● Replace illegible warning labels.
NOTICE
Device damage caused by incorrect voltage/insulation tests
Incorrect voltage/insulation tests can damage the device.
● Before carrying out a voltage/insulation check of the system/machine, disconnect the
devices as all converters and motors have been subject to a high voltage test by the
manufacturer, and therefore it is not necessary to perform an additional test within the
system/machine.
