Warnings in this manual appear in either of two ways:
• Dangerous voltage warnings, preceded by a Dangerous Voltage symbol,
indicate the presence of voltages which may cause death or serious injury.
These warnings describe procedures to avoid death or serious injury.
• General warnings, preceded by a General Warning symbol, indicate
situations or conditions which may cause death or serious injury. These
warnings describe procedures to avoid death or serious injury.
CAUTIONS inform you of situations or conditions which will damage
machinery or cause additional motor-operation down-time if you do not take
suggested steps to correct or address such situations or conditions.

less urgent than cautions and warnings, notes are important and should
not be ignored.
