For additional information, refer to NEMA ICS 1.1 (latest edition), "Safety Guidelines for the
Application, Installation, and Maintenance of Solid State Control" and to NEMA ICS 7.1 (latest
edition), "Safety Standards for Construction and Guide for Selection, Installation, and Operation of
Adjustable-Speed Drive Systems" or their equivalent governing your particular location.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
Disconnect all power from all equipment including connected devices prior to removing any
covers or doors, or installing or removing any accessories, hardware, cables, or wires except
under the specific conditions specified in the appropriate hardware guide for this equipment.
Always use a properly rated voltage sensing device to confirm that the power is off where and
when indicated.
Replace and secure all covers, accessories, hardware, cables, and wires and confirm that a
proper ground connection exists before applying power to the unit.
Use only the specified voltage when operating this equipment and any associated products.
Failure to follow these instructions will result in death or serious injury.
WARNING
LOSS OF CONTROL
The designer of any control wiring diagram 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
overtravel stop, power outage and restart.
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 unanticipated transmission delays or failures of the link.
Observe all accident prevention regulations and local safety guidelines.

Each implementation of this equipment 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.
