- Page 2 The information in this manual is subject to change without notice. Throughout this manual, the following notes are used to alert you to safety considerations: ATTENTION: Identifies information about practices or circumstances that can lead to personal injury or death, property damage, or economic loss. Important: Identifies information that is critical for successful application and understanding of the product.
- Page 3 ATTENTION: When the level-sense start feature is enabled (P.054 = ON), the user must ensure that automatic start up of the driven equipment will not cause injury to operating personnel or damage to the driven equipment. In addition, the user is responsible for providing suitable audible or visual alarms or other devices to indicate that this function is enabled and the drive may start at any moment.
- Page 4 Overcurrent or excess heating of the motor could result if this is not done. Failure to observe this precaution could result in damage to, or destruction of, the equipment. The following ATTENTION statements do not apply to the default Carrier VFD configuration. However, they do apply to the Reliance LiquiFlo AC Power Module.
- Page 5 Failure to observe this precaution could result in bodily injury. ATTENTION: Carrier Frequency (P.047) and Current Limit (P.005) must be set correctly before activating the identification procedure (H.020) to avoid motor overloading and/or overheating.
