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. Refer to the LiquiFlo Software Start-Up and Reference manual (D2-3410)for additional information. Failure to observe this precaution could result in severe bodily injury or loss of life.

ATTENTION: When P.055 is set to ON, the STOP/RESET key is functional only from the selected control source. As a safety precaution, Reliance recommends that an emergency stop input be located near the equipment. As a further safety precaution, the user should post a warning on the drive to alert personnel that the STOP/RESET key is not functional. Failure to observe this precaution could result in severe bodily injury or loss of life.

ATTENTION: Unused wires in conduit must be grounded at both ends to avoid a possible shock hazard caused by induced voltages. Also, if a drive sharing a conduit is being serviced or installed, all drives using this conduit should be disabled to eliminate the possible shock hazard from cross- coupled motor leads. Failure to observe these precautions could result in bodily injury.

ATTENTION: The drive contains printed circuit boards that are static-sensitive. Anyone who touches the drive components should wear an anti-static wrist band. Erratic machine operation and damage to, or destruction of, equipment can result if this procedure is not followed. Failure to observe this precaution can result in bodily injury.

ATTENTION: If a maintained start contact is used when the control source = rE, switching from local to remote from the terminal strip will cause power to be applied to the motor if the remote start contact is closed. Stay clear of rotating machinery in this case. Failure to observe this precaution could result in bodily injury.

ATTENTION: The drive is not equipped with a coast-stop pushbutton. You must install a hardwired operator-accessible pushbutton that provides a positive interrupt and shuts down the drive. See the LiquiFlo AC Power Modules Hardware Reference, Installation, and Troubleshooting manual (D2-3411) for wiring information. Failure to observe this precaution could result in bodily injury.

ATTENTION: The user is responsible for ensuring that driven machinery, all drive-train mechanisms, and application material are capable of safe operation at the maximum operating speed of the drive. In V/Hz regulation, overfrequency protection in the drive is provided by means of H.022. Failure to observe this precaution could result in bodily injury.

ATTENTION: The setting of parameters H.001 (Motor Nameplate Base Frequency), and P.004 (Maximum Speed) determines the motor maximum speed. These parameters must be set by a qualified person who understands the significance of setting them accurately. Failure to observe this precaution could result in bodily injury.

ATTENTION: When switching from auto to manual, or manual to auto, the drive will ramp to the reference level provided by the new source at the rate specified in P.001 (Accel Time 1), P.002 (Decel Time 1), P.017 (Accel Time 2), or P.018 (Decel Time 2). Be aware that an abrupt speed change may occur depending upon the new reference level and the rate specified in these parameters. Failure to observe this precaution could result in bodily injury.

ATTENTION: It is the user’s responsibility to determine how to distribute the passwords. Reliance Electric is not responsible for unauthorized access violations within the user’s organization. Failure to observe this precaution could result in bodily injury.

ATTENTION: Do not alter the setting of any jumper not described in LiquiFlo Hardware Reference manual (D2-3411). Failure to observe this precaution could result in damage to, or destruction of, the equipment.

ATTENTION: For single-motor applications with no external thermal overload relay, P.040 (Motor Overload Enable) should always be set to ON. Failure to observe this precaution could result in damage to, or destruction of, the equipment.
