ATTENTION:Use of power correction capacitors on the output of the drive can result in erratic
operation of the motor, nuisance tripping, and/or permanent damage to the drive. Remove power
correction capacitors before proceeding. Failure to observe this precaution could result in damage
to, or destruction of, the equipment.
ATTENTION:Most codes require that upstream branch circuit protection be provided to protect
input power wiring. Install the fuses recommended in table 3.7 of the LiquiFlo Hardware Reference
manual (D2-3411). Do not exceed the fuse ratings. Failure to observe this precaution could result
in damage to, or destruction of, the equipment.
ATTENTION:Do not route signal and control wiring with power wiring in the same conduit. This
can cause interference with drive operation. Failure to observe this precaution could result in
damage to, or destruction of, the equipment.
ATTENTION:Distribution system short circuit capacity shall not exceed the rating of the drive.
Failure to observe this precaution could result in damage to, or destruction of, the equipment.
ATTENTION:H.002 (Motor Nameplate Amps) must not exceed the rated amps found on the motor
nameplate. 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.
ATTENTION:As a safety precaution, Reliance Electric recommends that you provide an audible
or visual alarm to indicate that the level sense start feature is enabled and the motor can start
when power is applied to the drive. You should also post warnings on the motor, the drive, and
any other applicable equipment to alert personnel that the application uses an automatic start-
up feature. Failure to observe this precaution could result in severe bodily injury or loss of life.
ATTENTION:Be aware of the following before enabling the level sense start function (P.054):
• Setting P.054 to ON immediately applies output power to the motor when all start conditions are
met.
• If the drive is running from the terminal strip, both the start and stop inputs are closed. If P.054 =
ON and a fault occurs, the drive coasts to rest and generates a fault. In this case, resetting and
clearing the fault immediately restarts the drive without any change to the start or stop input
states
• If P.026 (Function Loss Response) = 1, the control source is the terminal strip (start and stop
inputs are closed), and P.054 = ON, the drive coasts to rest if the function loss input is opened
and does not generate a fault. In this case, closing the function loss input immediately starts the
drive without any change to the start or stop input.
When this function is enabled, 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. Failure to observe this
precaution could result in severe bodily injury or loss of life.
ATTENTION:If P.062 (Option Port: Communication Loss Response) = 2 and P.054 (Level Sense
Start Enable) = ON and network communication is lost while the drive is running, the terminal
strip stop input will function as a STOP/RUN input. If the terminal strip stop input is opened, the
drive will stop. If the terminal strip stop input is closed, the drive will re-start. Failure to observe
this precaution could result in severe bodily injury or loss of life.
ATTENTION:When starting with search enabled (H.016 is set to any value but OFF), there will
be a several second delay, and the motor may drift in the forward and reverse direction, before
the motor begins operating in the desired direction even if reverse has been disabled in P.027.
Stay clear of rotating machinery. Failure to observe this precaution could result in bodily injury.
