2.2 Safety Concept
2.2Safety Concept
The medium-voltage variable frequency drive (VFD) and its components are subject to a
comprehensive safety concept which, when properly implemented, ensures safe installation,
operation, servicing, and maintenance.
The safety concept encompasses safety components and functions to protect the device and
operators.
The VFD is also equipped with monitoring functions to protect external components.
The VFD operates safely when the interlock and protection systems are functioning properly.
Nevertheless, there are areas on the medium-voltage drive that are hazardous for personnel
and that can cause material damage if the safety instructions described in this section and
throughout the product documentation are not strictly observed.

2.4 Safety Information and Warnings
2.4Safety 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 specified in
IEC 61800-5-1.
● 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 off 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
which contains extra low voltages (ELV).
● 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.
● Only qualified individuals should install, operate, troubleshoot, and maintain this VFD. A
qualified individual is "a person, who is familiar with the construction and operation of the
equipment and the hazards involved."
● Hazardous voltages may still exist within the VFD cabinets even when the disconnect
switch is open (off) and the supply power is shut off.
● When a system is configured 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 input voltage is removed from
the VFD.

2.4 Safety Information and Warnings
WARNING
Potential Arc Hazard
● Arcing can result in damage to property, serious injury and even death.
● The equipment has not been tested and rated for arc flash 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 defined as suitable in the technical description.
– in combination with equipment and components supplied by other manufacturers which
have been approved and recommended by Siemens.
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 (for example, CPU battery, capacitors, etc.).
● Always ensure the use of an even and flat truck bed to transport the VFD system. Before
unloading, be sure that the concrete pad is level for storage and permanent positioning.
● Always confirm 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 flammable material in, on, or near the drive enclosure. This includes
equipment drawings and manuals.
● Never use fork trucks to lift cabinets that are not equipped with lifting tubes. Be sure that
the fork truck tines fit the lifting tubes properly and are the appropriate length.

2.5 ESD-sensitive Components
2.5ESD-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 qualified 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 vacuumstyle 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.
