Operating Instructions 05/2020 13

5 safety rules
1. Disconnect the system.
Also disconnect the auxiliary circuits, for example, anti-condensation heating.
2. Secure against reconnection.
3. Verify absence of operating voltage.
4. Ground and short-circuit.
5. Provide protection against adjacent live parts.
To energize the system, apply the measures in reverse order.
2.4 Safe handling
Electric shock 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 parts can result in death,
serious injury and material damage
● Isolate all components that can feed voltage to the drive before commencing work.
Electric shock due to high voltages in 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. Touching live parts can result in death or serious injury.
● Carefully comply with the 5 safety rules (Page 13).
● Operate the device properly.
● Service and maintain the device regularly and correctly.
Electric shock caused by induced voltage
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. Touching live parts can result in death or serious
injury.
● Before opening the doors, wait until the connected machine has come to a standstill.
Safety instructions
2.4 Safe handling
SINAMICS SH150 6SL3805
14 Operating Instructions 05/2020

Danger to life as a result of high voltages at the capacitors and in the DC link
High voltages are still present at the capacitors of the power cell and at the DC link even after
the system has been shut down. Touching live parts can result in death or serious injury.
● A label on the drive specifies the discharge times of the DC link capacitors. Only open the
drive once these discharge times have elapsed.
● Observe the five safety rules when performing any work.
Electric shock caused by dangerous auxiliary voltages
Danger voltages are still present even after shutdown. Touching live parts can result in death
or serious injury.
● Carefully comply with the 5 safety rules.
Danger caused by arcing
Hazards caused by arcing can occur as result of the following factors, for example:
Input currents above the permissible limits, incorrectly dimensioned circuit breakers or
transformers, incorrectly connected or unconnected cables, dirt, objects that have been
forgotten, e.g. tools used for installation.
Arcing can result in death, serious injury or material damage.
● As system operator, carefully ensure that the system has been professionally designed and
dimensioned.
● Correctly connect the power cables. The maximum permissible input currents are listed in
the "Technical specifications".
● Remove contamination and dirt.
● After installation and mounting, carefully check that no objects have been left in the device.
Burns caused by fire escaping from the pressure relief flaps
Fire can escape through the pressure relief flaps if arcing occurs. Persons who are on the roof
section of the drive can suffer severe burns. Objects that are on the roof section of the drive can
catch fire or be flung into the room. Death, serious injury or material damage can result.
● Never climb on the drive. Never place any objects on the roof section of the drive.
Danger due to live stationary parts, 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 covers.
Safety instructions
2.4 Safe handling
SINAMICS SH150 6SL3805
Operating Instructions 05/2020 15

Risk of burns due to hot component surfaces
Certain components (e.g. the heat sink and reactor) can become very hot during operation.
These components can remain hot for a long time after operation. Severe skin injuries (burns)
can result when coming into contact with these components.
● After the device has been shut down, do not touch any hot components.
Risk of injury at 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 carry out work in the upper section using unsuitable ladders or similar,
you can fall and injure yourself.
● Use appropriate protective equipment, especially a hard hat and gloves.
● Use suitable steps or ladders when working in the upper area.
Eye and skin injuries caused by deionized water
Deionized water is harmful to eyes and skin and can damage surfaces.
● Therefore, use appropriate protective clothing when you carry out any work on the drive.
However, if your eyes or skin do come into contact with deionized water, rinse the affected
area thoroughly with tap water as soon as possible.
● If deionized water leaks out, eliminate the source of the problem and remove the liquid from
the surfaces affected.
● Please refer to the EU safety data sheet of the coolant manufacturer.
Shutdown as a result of an incorrect residual current monitoring device
If you use a residual current monitoring device (RCD), it is possible that the residual current
monitoring device will trip in error (nuisance trip). The converter 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.
2.5 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.
Interference with pacemakers
The functioning of cardiac pacemakers could be impaired by electromagnetic fields. Death or
serious physical injury can result.
● It is therefore not permissible for people with pacemakers to stand close to the device.

2.7.3 Installation site safety
Danger due to an unsecured installation location
This device is used in industrial power installations. Improper use, incorrect operation,
insufficient maintenance, and access by unauthorized persons can lead to accidents. The
results can be death, serious bodily injury or damage to property.
● Install the device in electrical rooms where only qualified personnel have access. If this is
not possible, then ensure that a barrier prevents uncontrolled access. Use safety fences and
appropriate signs, for example, to prevent unauthorized entry to the zone that has been
fenced off.
● Place notices that indicate that only trained personnel are allowed to operate and carry out
maintenance and repair work.
● To comply with safety regulations, equip plants and systems with additional monitoring and
protective devices. Follow technical equipment legislation and accident prevention
regulations.
Note
The drive does not have a grounding breaker at the input/output. The system operator must,
therefore, ensure that there is sufficient grounding.
2.7.4 Measures for operator protection in electromagnetic fields
The plant operator is responsible for taking the following appropriate measures (labels and
hazard warnings) to adequately protect operating personnel against any possible risk.
● Observe the relevant nationally applicable health and safety regulations or the applicable
national regulations in the country of installation. In Germany, "electromagnetic fields" are
subject to regulations BGV B11 and BGR B11 stipulated by the German statutory industrial
accident insurance institution.
● Display adequate hazard warning notices on the installation.
● Place barriers around hazardous areas.
● Take measures, e.g. using shields, to reduce electromagnetic fields at their source.
● Make sure that personnel are wearing the appropriate protective gear.
