Loss of Control
WARNING
LOSS OF CONTROL
•
Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
•
The designer of any control scheme must consider the potential failure modes of control
paths and, for certain critical control functions, provide a means to achieve a safe state
during and after a path failure. Examples of critical control functions are emergency stop
and over travel stop.
•
Separate or redundant control paths must be provided for critical control functions.
•
System control paths may include communication links. Consideration must be given to the
implications of anticipated transmission delays or failures of the link.
•
Each implementation of equipment utilizing communication links must be individually and
thoroughly tested for proper operation before being placed into service.
Failure to follow these instructions can result in death, serious injury, or equipment
damage.

Electrostatic Discharge
NOTICE
STATIC SENSITIVE COMPONENTS
Circuit boards and option cards can be damaged by static electricity. Observe the electrostatic
precautions below when handling controller circuit boards or testing components.
Failure to follow these instructions can result in equipment damage.
Observe the following precautions for handling static-sensitive components:
•
Keep static-producing material such as plastic, upholstery, and carpeting out of the
immediate work area.
•
Store static-sensitive components in protective packaging when they are not installed in
the drive.
•
When handling a static-sensitive component, wear a conductive wrist strap connected
to the component or drive through a minimum of 1 megohm resistance.
•
Avoid touching exposed conductors and components leads with skin or clothing.

For additional information about anticipated transmission delays or failures of the link, refer to NEMA ICS 1.1 (latest edition),
Safety Guidelines for the Application, Installation and Maintenance of Solid State Control
or its equivalent.
