WARNING
LOSS OF CONTROL
• 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 overtravel 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 unanticipated
transmission delays or failures of the link.a
Failure to follow these instructions can result in death, serious injury, or equipment damage.
a.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.”
CAUTION

INCOMPATIBLE LINE VOLTAGE

Before turning on and configuring the drive, ensure that the line voltage is compatible with the supply voltage range shown on the drive
nameplate. The drive may be damaged if the line voltage is not compatible.
Failure to follow these instructions can result in injury or equipment damage.
CAUTION
RISK OF DAMAGE TO THE MOTOR
