Fundamental safety instructions 1
1.1 General safety instructions
WARNING
Electric shock and danger to life due to other energy sources
Touching live components can result in death or severe injury.
● Only work on electrical devices when you are qualified for this job.
● Always observe the country-specific safety rules.
Generally, the following six steps apply when establishing safety:
1. Prepare for disconnection. Notify all those who will be affected by the procedure.
2. Isolate the drive system from the power supply and take measures to prevent it being
switched back on again.
3. Wait until the discharge time specified on the warning labels has elapsed.
4. Check that there is no voltage between any of the power connections, and between any
of the power connections and the protective conductor connection.
5. Check whether the existing auxiliary supply circuits are de-energized.
6. Ensure that the motors cannot move.
7. Identify all other dangerous energy sources, e.g. compressed air, hydraulic systems, or
water. Switch the energy sources to a safe state.
8. Check that the correct drive system is completely locked.
After you have completed the work, restore the operational readiness in the inverse sequence.
WARNING
Electric shock due to connection to an unsuitable power supply
When equipment is connected to an unsuitable power supply, exposed components may
carry a hazardous voltage that might result in serious injury or death.
● 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.
Machine control panel: MCP 398C
Manual, 12/2017, A5E43199783B AA 5

WARNING
Electric shock due to equipment damage
Improper handling may cause damage to equipment. 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
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
Electric shock if there is no ground connection
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
Spread of fire from built-in devices
In the event of fire outbreak, the enclosures of built-in devices cannot prevent the escape of
fire and smoke. This can result in serious personal injury or property damage.
● Install built-in units in a suitable metal cabinet in such a way that personnel are protected
against fire and smoke, or take other appropriate measures to protect personnel.
● Ensure that smoke can only escape via controlled and monitored paths.

WARNING
Unexpected movement of machines caused by radio devices or mobile phones
When radio devices or mobile phones with a transmission power > 1 W are used in the
immediate vicinity of components, they may cause the equipment to malfunction.
Malfunctions may impair the functional safety of machines and can therefore put people in
danger or lead to property damage.
● If you come closer than around 2 m to such components, switch off any radios or mobile
phones.
● Use the "SIEMENS Industry Online Support App" only on equipment that has already been
switched off.
WARNING
Fire due to inadequate 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
Unexpected movement of machines caused by inactive safety functions
Inactive or non-adapted safety functions can trigger unexpected machine movements that
may result in 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.
