Operating Instructions Rev.201910281433 EXAMPLE 13

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
Danger as a result of high voltages from external supplies
Even if the circuit breaker is open, parts of the converter 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 converter, but can also occur with components that are
electrically connected to the converter (e.g. circuit breakers or isolators). Touching live parts
can result in death, serious injury, and damage to property.
● Isolate all components that can feed voltage to the converter before commencing work.
Danger due to high voltage 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. High voltages can cause death or serious injury if the safety rules are
not observed or if the equipment is handled incorrectly.
● Operate the device properly.
● Always follow the "The five safety rules (Page 13)" when performing any work.
● Service and maintain the device regularly and correctly.
Danger as a result of 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.
Danger due to high auxiliary voltages
High auxiliary voltages are still present even after shutdown. Touching live parts can result in
death or serious injury.
● Observe the five safety rules when performing any work.
Safety information
2.4 Safe handling
SINAMICS SL150 6SL38600UL432AA0Z
14 Operating Instructions Rev.201910281433 EXAMPLE

Danger due to 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.
● Contamination and dirt.
● Tools that have been forgotten, e.g. when mounting and installing the equipment.
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 contamination and dirt.
● After installation and mounting, carefully check that no objects have been left in the device.
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.
Risk of burns due to 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.
● After the device has been shut down, do not touch any hot components.
Risk of burns due to 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.
● Ensure that the anti-condensation heating cannot be touched.
● Ensure that the anti-condensation heating is switched off before carrying out any repair or
maintenance work.

2.4 Safe handling
SINAMICS SL150 6SL38600UL432AA0Z
Operating Instructions Rev.201910281433 EXAMPLE 15

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.
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.
WARNING
Interference with pacemakers
The functioning of cardiac pacemakers could be impaired by electromagnetic fields. Death or
serious physical injury can result.
● As a consequence, it is not permissible for people with pacemakers to stand close to the

2.7.2 Grounding concept
Draw-up a grounding concept and integrate the device into this concept. The grounding
concept must take into consideration national provisions and system specifics. Ensure that the
following criteria are fulfilled:
● At the installation site, the various subunits must be screwed together to establish a good
electrical connection between them.
● If shield busbars are provided, these must be connected together.
● The protective grounding conductor must be connected to the system the grounding point.
Select the highest cross-section of the protective grounding conductor from one of the
following variants:
– According to local wiring regulations
– Calculated according to IEC 60364-5-54, 543.1
– Half a phase conductor cross-section
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 converter will be supplied on request without an electromechanical door interlocking
system if space is restricted. In this instance, the customer must provide an access interlock
system compliant with IEC 61800-5 /-1.
