SINAMICS SM120 6SL38715
Operating Instructions 07/2015 13

2.3 Safe handling
WARNING
High voltages from external supplies
Even if the circuit breaker is open, parts of the drive can be under voltage (live) as a result of
the auxiliary voltage at the premagnetization, precharging or demagnetization transformers.
This danger is not limited to the drive, but can also occur with components that are electrically
connected to the drive (e.g. circuit breakers or isolators). Touching live components can result
in death, serious injury, or material damage.
Therefore, isolate all components that can feed voltage to the drive before commencing work.
WARNING
High voltages during operation
When operating this equipment very high voltages develop. Even after switching off the mains
voltage, or while the connected machine is still turning, high voltages can remain for a
prolonged length of time. High voltages can cause death or serious injury if the safety rules
are not observed or if the equipment is handled incorrectly.
● Operate the drive properly.
● Always follow the "The five safety rules (Page 13)" when performing any work.
● Only remove the covers using the methods described by these operating instructions.
● Maintain the drive regularly and correctly.
WARNING
High voltages from machines still turning and connected
Rotating machinery can induce dangerous high voltages and synchronous motors that are
not de-excited immediately can also pose a hazard. If the connection to the motor is not
isolated or grounded, these voltages can also remain. If live parts are touched, this can result
in death and serious physical injuries.
Before opening the doors, wait until the connected machine has come to a standstill.
WARNING
High voltages from DC-link capacitors
High voltages are still present at the DC-link capacitors even after shutdown. If live parts are
touched, this can result in death or serious physical injury.
● Wait for the DC-link capacitor's discharge time specified on the device label. Do not touch
the device during this time.
● Observe the five safety rules when performing any work.
Safety instructions
2.3 Safe handling
SINAMICS SM120 6SL38715
14 Operating Instructions 07/2015

WARNING
High auxiliary voltages
High auxiliary voltages are still present even after shutdown. If live parts are touched, this
can result in death or serious physical injury.
Observe the five safety rules when performing any work.
WARNING
Hazardous arcing
Hazards caused by arcing can occur as result of the following factors, for example:
● The input currents are exceeded
● Incorrectly dimensioned circuit breaker or transformers
● Incorrectly connected cables or cables that have not been connected
● Excessive pollution
Arcing can result in death, serious injury or material damage.
● Make sure that the system is properly dimensioned and that the power cables are correctly
connected. The maximum permissible input currents are listed in the "Technical
specifications".
● Remove any excessive pollution.
WARNING
Live, moving or rotating parts
Contact with the parts mentioned can result in death, serious physical injury or damage to
property.
● Observe the instructions regarding installation and operation.
● Always take protective measures before touching any components.
● Do not remove any necessary covers.
WARNING
Hot component surfaces
Certain components (e.g. heat sinks and reactors) can become very hot during operation.
These components can remain hot for a long time after operation. Contact can result in serious
injury, such as skin burns.
Do not touch hot components even after you have switched off the drive.
Safety instructions
2.3 Safe handling
SINAMICS SM120 6SL38715
Operating Instructions 07/2015 15

WARNING
Hot anti-condensation heating surface
When the temperature control limit value is reached the anti-condensation heating is switched
on. Once activated, the anti-condensation heating can generate a great deal of heat. Contact
can result in serious injury, such as skin burns.
Do not touch the anti-condensation heating.
CAUTION
Places that are difficult to access
If you do not use appropriate protective equipment when working in places that are difficult
to access you are at risk of injury. For example, sharp edges and splinters can cause injuries
to the head and skin. If you use unsuitable steps when working on the upper areas of the
drive, you can fall and injure yourself.
● Use appropriate protective equipment, especially a hard hat and gloves.
● In the upper areas of the drive, use suitable steps.
NOTICE
Unsuitable residual current monitoring device
If you operate the drive together with a residual current monitoring device (RCD), it is possible
the residual current monitoring device will trip in error (nuisance trip). The drive may be
switched off as a result of the protection device tripping in error.
To minimize the risk of faulty trips, use a type-B RCD.
2.4 Electromagnetic fields in electrical power engineering installations
Electromagnetic fields are generated during operation of electrical power engineering
installations. Electromagnetic fields can interfere with electronic devices, These devices can
malfunction if electromagnetic fields are present.
WARNING
Interference with pacemakers
The functioning of cardiac pacemakers could be impaired by electromagnetic fields. Death
or serious physical injury can result.
People with pacemakers are therefore not allowed to stay close to the drive.
