Safety notes 3
3.1 General Safety Information
Proper Use
SINAMICS Perfect Harmony™ GH180 medium voltage drives must always be installed in closed
electrical operating areas. The drive is connected to the industrial network via a circuit-breaker
or contactor that is electrically connected to the VFD control to enable the drive protection
features.
The speci󹪝c transport conditions must be observed when the equipment is transported. The
equipment shall be assembled/installed and the separate cabinet units connected properly by
cable and/or busbar in accordance with the assembly/installation instructions. The relevant
instructions regarding correct storage, EMC-compliant installation, cabling, shielding and
grounding and an adequate auxiliary power supply must be strictly observed. Fault-free
operation is also dependent on careful operation and maintenance.
The power sections are designed for variable-speed drives use with synchronous and
asynchronous motors. Operating modes, overload conditions, load cycles, and ambient
conditions di󹪜erent to those described in this document are allowed only by special
arrangement with the manufacturer.
Commissioning should only be carried out by trained service personnel in accordance with the
commissioning instructions.
System components such as circuit-breaker, transformer, cables, cooling unit, motor, speed
sensors, etc., must be matched to VFD operation. System con󹪝guration may only be carried out
by an experienced system integrator.

3.3 Safety Information and Warnings
DANGER
Hazardous Voltage!
•Always follow the proper lock-out/tag-out procedures before beginning any maintenance
or troubleshooting work on the VFD.
•Always follow standard safety precautions and local codes during installation of external
wiring. The installation must follow wiring practices and insulation systems as speci󹪝ed in
IEC 61800-5-1.
•Hazardous voltages may still exist within the VFD cabinets even when the disconnect
switch is open (o󹪜) and the supply power is shut o󹪜.
•Only quali󹪝ed individuals should install, operate, troubleshoot, and maintain this VFD. A
quali󹪝ed individual is "a person, who is familiar with the construction and operation of the
equipment and the hazards involved."
•Always work with one hand, wear electrical safety gloves, wear insulated electrical hazard
rated safety shoes, and safety goggles. Also, always work with another person present.
•Always use extreme caution when handling or measuring components that are inside the
enclosure. Be careful to prevent meter leads from shorting together or from touching other
terminals.
•Use only instrumentation (e.g., meters, oscilloscopes, etc.) intended for high voltage
measurements (that is, isolation is provided inside the instrument, not provided by isolating
the chassis ground of the instrument).
•Never assume that switching o󹪜 the input disconnector will remove all voltage from
internal components. Voltage is still present on the terminals of the input disconnector.
Also, there may be voltages present that are applied from other external sources.
•Never touch anything within the VFD cabinets until verifying that it is neither thermally hot
nor electrically alive.
•Never remove safety shields (marked with a HIGH VOLTAGE sign) or attempt to measure
points beneath the shields.
•Never operate the VFD with cabinet doors open. The only exception is the control cabinet.
•Never connect any grounded (i.e., non-isolated) meters or oscilloscopes to the system.
•Never connect or disconnect any meters, wiring, or printed circuit boards while the VFD is
energized.
•Never defeat the instrument’s grounding.
• When a system is con󹪝gured with VFD bypass switchgear (e.g. contactors between line and
motor, and VFD and motor), these switches should be interlocked so that the line voltage
is never applied to the VFD output if the medium voltage input is removed from the VFD.
• When a system is con󹪝gured with VFD pre-charge, medium voltage is present on the
primary side of the input transformer and upstream device even though the MV contactor
is not closed.

• Arcing can result in damage to property, serious injury and even death.
• The equipment has not been tested and rated for arc 󹪞ash protection.
• Avoiding arc hazard risks is dependent upon proper installation and maintenance.
• Incorrectly applied equipment, incorrectly selected, connected or unconnected cables, or
the presence of foreign materials can cause arcing in the equipment.
• Follow all applicable precautionary rules and guidelines as used in working with medium
voltage equipment.
• The equipment may be used only:
– for the applications de󹪝ned as suitable in the technical description.
– in combination with equipment and components supplied by other manufacturers
which have been approved and recommended by Siemens.
• Always follow the facility / installation site rules / guidelines for Personal Protectiive
Equipment (PPE) based on the Arc Flash study of that facility.
Additional safety precautions and warnings appear throughout this manual. These important
messages should be followed to reduce the risk of personal injury or equipment damage.
WARNING
Obey Rules to Avoid Risk of Death
•Always comply with local codes and requirements if disposal of failed components is
necessary.
•Always ensure the use of an even and 󹪞at truck bed to transport the VFD system. Before
unloading, be sure that the concrete pad is level for storage and permanent positioning.
•Always con󹪝rm proper tonnage ratings of cranes, cables, and hooks when lifting the VFD
system. Dropping the cabinet or lowering it too quickly could damage the unit.
•Never disconnect control power while medium voltage is energized. This could cause
severe system overheating and/or damage.
•Never store 󹪞ammable material in, on, or near the drive enclosure. This includes equipment
drawings and manuals.

3.4 ESD-sensitive Components
Guidelines for Handling Electrostatic Sensitive Devices (ESD)
NOTICE
ESD Sensitive Equipment
• Always be aware of electrostatic discharge (ESD) when working near or touching
components inside the VFD cabinet. The printed circuit boards contain components that are
sensitive to electrostatic discharge. Handling and servicing of components that are
sensitive to ESD should be done only by quali󹪝ed personnel and only after reading and
understanding proper ESD techniques. The following ESD guidelines should be observed.
Following these rules can greatly reduce the possibility of ESD damage to printed circuit
board (PCB) components.
• Always transport static sensitive equipment in antistatic bags.
• Always use a soldering iron that has a grounded tip. Also, use either a metallic vacuum-style
plunger or copper braid when desoldering.
• Ensure that anyone handling the printed circuit boards is wearing a properly grounded static
strap. The wrist strap should be connected to ground through a 1 Megohm resistor.
Grounding kits are available commercially through most electronic wholesalers.
• Static charge build-up can be removed from a conductive object by touching the object with
a properly grounded piece of metal.
• When handling a PC board, always hold the card by its edges.
• Do not slide printed circuit boards (PCBs) across any surface (e.g., a table or work bench).
If possible, perform PCB maintenance at a workstation that has a conductive covering that
is grounded through a 1 Megohm resistor. If a conductive tabletop cover is unavailable, a
clean steel or aluminum tabletop is an excellent substitute.
• Avoid plastic Styrofoam™, vinyl and other non-conductive materials. They are excellent
static generators and do not give up their charge easily.
• When returning components to Siemens Industry, Inc. always use static-safe packing. This
limits any further component damage due to ESD.
Components that can be destroyed by electrostatic discharge (ESD)
NOTICE
Electrostatic discharge
Electronic components can be destroyed in the event of improper handling, transporting,
storage, and shipping.
Pack the electronic components in appropriate ESD packaging; e.g. ESD foam, ESD packaging
bags and ESD transport containers.
To protect your equipment against damage, follow the instructions given below.
Safety notes

Type 6SR5 Air-Cooled
Operating Instructions, AK, A5E39390112 17

• Avoid physical contact with electronic components. If you need to perform absolutely
essential work on these components, then you must wear one of the following protective
gear:
– Grounded ESD wrist strap
– ESD shoes or ESD shoe grounding strips if there is also an ESD 󹪞oor.
• Do not place electronic components close to data terminals, monitors or televisions.
Maintain a minimum clearance to the screen (> 10 cm).
• Electronic components should not be brought into contact with electrically insulating
materials such as plastic foil, plastic parts, insulating table supports or clothing made of
synthetic 󹪝bers.
• Place components in contact with ESD-suited materials e.g. ESD tables, ESD surfaces, ESD
packaging.
• Measure on the components only if one of the following conditions is met:
– The measuring device is grounded with a protective conductor.
– The measuring head of a 󹪞oating measuring device has been discharged directly before
the measurement.
The necessary ESD protective measures for the entire working range for electrostatically
sensitive devices are illustrated once again in the following drawings. Precise instructions for
ESD protective measures are speci󹪝ed in the standard IEC 61340-5-1.
