In the individual chapters of this document, you will find safety instructions that must be obeyed
absolutely, for your own safety, to protect other people and to avoid damage to property.
Carefully comply with the following safety instructions when performing all of the activities.
2.1 Warning symbol on the device
Please observe the warning symbols attached to the device. The warning symbols have the
following meaning:
Warning symbol Meaning
Warning: Voltage
Warning: Hot surface
General warning symbol: Observe the explanations about the hazard on the
device labels.
For transportation, observe the "transportation markings (Page 64)" on the device packaging.
2.2 Qualified personnel
The product/system described in this documentation may only be operated by personnel
qualified for the specific task in accordance with the relevant documentation for the specific
task, in particular its warning notices and safety instructions. Because of their training and
experience, qualified personnel can recognize any risks involved with handling these products/
systems and avoid any possible dangers.
2.3 The 5 safety rules
To ensure your own personal safety as well as to avoid material damage, always comply with
the safety-relevant instructions when carrying out any work. Also carefully comply with the 5
safety rules according to EN 50110‑1 "Working in a no-voltage state" in the specified sequence.
5 safety rules
1. Disconnect the system.
Also disconnect the auxiliary circuits, for example, anti-condensation heating.
2. Secure against reconnection.
SINAMICS GM150 6SL3835-2LN44-2AA0
Operating Instructions Rev.201910281250 MUSTER 17

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. 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 17)" when performing any work.
● Service and maintain the device regularly and correctly.
Electric shock if the grounding switch is defective
A grounding switch is a component that has an associated certain probability of failure. This
means that it is possible that the feedback signal regarding the switching state no longer
matches the actual switching state of the grounding switch. This means that if the power unit
door is open, hazardous voltages could still be present at the active parts of the drive. Touching
the device can result in death or serious injury.
● Check the function of the grounding switch before carrying out any other work at the drive.
● Carefully comply with the 5 safety rules (Page 17).

18 Operating Instructions Rev.201910281250 MUSTER

Electric shock due to 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.
Electric shock at DC link capacitors
High voltages are still present at the DC link capacitors even after shutdown. Touching live
parts can result in death or serious injury.
● A label specifies the discharge times of the DC link capacitors. Only open the doors once
these discharge times have elapsed.
● Observe the five safety rules when performing any work.
Electric shock caused by 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.
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.

SINAMICS GM150 6SL3835-2LN44-2AA0
Operating Instructions Rev.201910281250 MUSTER 19

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.
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.
