type B from ABB, Siemens, or Bender.
System Integration
Precautions
The following precautions are provided as general
guidelines for the setup of the W7B ASD within the
system.
• The W7B ASD is a general-purpose product.
It is a system component only and the system
design should take this into consideration.
Please contact the TIC Customer Support
Center for application-specific information or for
training support.
• The W7B ASD is part of a larger system and
the safe operation of the ASD will depend on
observing certain precautions and performing
proper system integration.
• Improperly designed or improperly installed
system interlocks may render the motor unable
to start or stop on command.
• The failure of ancillary components may
cause intermittent system operation (i.e., the
system may start the motor without warning).
• A detailed system analysis and job safety
analysis should be performed by the systems
designer and/or systems integrator before the
installation of the ASD component. Contact the
TIC Customer Support Center for options
availability and for application-specific system
integration information if required.
Personnel Protection
• Installation, operation, and maintenance
should be performed by Qualified Personnel
Only.
• A thorough understanding of the ASD will be
required before the installation, operation, or
maintenance of the ASD.

purposeful or inadvertent actions of workers.
Insulators, machine guards, and electrical
safeguards are to be inspected (and tested
where possible) at installation and periodically
after installation for potential hazardous
conditions.
•DO NOT allow personnel near rotating
machinery. Warning signs to this effect shall be
posted at or near the machinery.
•DO NOT allow personnel near exposed
electrical conductors. Contact with electrical
conductors can be fatal. Warning signs to this
effect shall be posted at or near the hazard.
• Personal Protection Equipment (PPE) shall
be provided and used to protect employees
from any hazards inherent to system operation.
System Setup Requirements
• When using the ASD as an integral part of a
larger system, it is the responsibility of the
ASD installer/maintenance personnel to ensure
that there is a fail-safe in place (i.e., an
arrangement designed to switch the system to
a safe condition if there is a fault or failure).
• The failure of external or ancillary
components may cause intermittent system
operation (i.e., the system may start the motor
without warning).
• Power factor improvement/correction
capacitors or surge absorbers MUST NOT be
installed on the output of the ASD.
• Use of the built-in system protective features
is highly recommended (i.e., E-Off, Overload
Protection, etc.).
• The operating controls and system status
indicators should be clearly readable and
positioned where the operator can see them
without obstruction.
• Additional warnings and notifications shall be
posted at the equipment installation location as
deemed required by Qualified Personnel.
• System safety features should be designed
and employed into the integrated system in a
manner such that system operation, even in the
event of system failure, will not cause harm or
result in system damage or injury to personnel
(i.e., E-Off, Auto-restart settings, System
Interlocks, etc.)
• The programming setup and system
configuration of the ASD may allow it to start
the motor unexpectedly. A familiarity with the
Auto-restart and the Hand/Auto settings and
function is a requirement to use this product.
• There may be thermal or physical properties,
or ancillary devices integrated into the overall
system that may allow for the ASD to start the
motor without warning. Signs to this effect must
be posted at the equipment installation
location.
• If a secondary magnetic contactor (MC) or
an ASD output disconnect is used between the
ASD and the load, it should be interlocked to
halt the ASD before the secondary contact
opens. If the output contactor is used for
bypass operation it must be interlocked such
that commercial power is never applied to the
ASD output terminals (U, V, W).
• When using an ASD output disconnect, the
ASD and the motor must be stopped before the
disconnect is either opened or closed. Closing
the output disconnect while the 3-phase output
of the ASD is active may result in equipment
damage or injury to personnel.

CE Directive
In addition to local and regional safety
requirements, the Electromagnetic Compatibility
(EMC) Directive and the Low-Voltage Directive
make it obligatory to put the European Conformity
(CE) certification mark on all relevant products
placed in the European market. It is the
responsibility of the manufacturer to ensure that this
mark is visible on its final products.
Although ASDs are not subject to the EMC
Directive because they are used in combination
with other machinery, the CE mark must be placed
on relevant ASDs because they are subject to the
low-voltage directive.
The Low-Voltage Directive provides for the safety of
machines and systems. All W7B ASDs are CE-
marked in accordance with the European Standard
EN 50178 specified by the latest revision of the
Low-Voltage Directive on Electrical Safety, and are
available in the European market.
ASDs are not individually tested to check for CE
compliance because compliance is based on how
the ASD has been installed and connected. The
W7B ASD complies with the CE directive once the
recommended filter has been installed and is
properly wired.
TIC also complies with European standards 60529,
60721-3-3 (environment conditions), and 60068-2-6
(vibrations).
EMC Installation Guidelines
All systems placed on the European market are
required to comply with the latest revision of the
European Conformity directive regarding EMC.
EMC standards are divided into immunity-related
standards and emission-related standards.
Standards are further categorized according to the
operating environment of the ASD.

Safety Information and Precautions
W7B ASD Installation & Operation Manual
TIC has applied the following standards for systems
deployed in the European market:
General EMC Guidelines for
Compliance
• Input EMI filters to reduce transmission and
radiation noise (Tabl e 3 and Tab l e 4 ).
• Use shielded power and control cables.
• Minimize cable lengths and DO NOT route
them parallel or bind them together.
• Earth the steel cabinet containing the ASD
and the control panel securely.
• Keep control and power cabling separated.
•DO NOT route the input and output cables
together.
• Insert an iron core in shielded cables.
