3.4.13 Inspect the Power Unit Jumper (J30)
Important: An optional Power Interface module, for drives which are powered from a
690 Vrms AC line, is available only on drives manufactured by Reliance
Electric Dierikon, Switzerland. In order to operate properly with this new
power I/F module, a hardware jumper (J30) was added to the regulator
board. This jumper must be set according to the type of power interface
module installed in the drive. Jumper positions are labeled “LOW” and
“HI”.
Jumper J30 must be set to “HI” if the drive nameplate indicates that the AC line input
voltage is 690 Vrms. Otherwise, J30 must be set to “LOW”.
Improper setting of jumper J30 can cause the drive to operate at the wrong speed if
configured as a voltage regulator, nuisance AC line voltage high/low alarms and
incorrect armature and AC line voltage displays. J30 is not supplied with U.S. Drives.
3.5 Power Up the Drive
Apply AC power to the drive after you complete the power off inspection, motor ground
check, and drive setup procedures.
See the OIM instruction manual for the displays during power-up.
3.6 Verify the Correct Direction of Motor Rotation
Step 1. Disconnect and lock out all incoming power to the drive.
Step 2. Verify the operation of the Coast/Stop pushbutton using an ohmmeter. When
the pushbutton is pressed, the ohmmeter should read infinite ohms (open);
when released, it should read 0 (short).
Step 3. Turn power to the drive ON.
!
ATTENTION: The drive can operate at excessive armature voltage and
speed if J30 is improperly set to the LOW position when it should be set
to HI.
!
ATTENTION: The user must provide an external operator-accessible
coast/stop pushbutton at terminals 7 and 8 on the Regulator board to
disable the machine in case of improper operation. Uncontrolled machine
operation might result if this is not done. Failure to observe this precaution
could result in severe bodily injury or loss of life.
ATTENTION: If tachometer rotation is incorrect, sudden and rapid
acceleration may result, which can cause overspeed of the drive. Failure
to observe this precaution could result in bodily injury.
