Precautions
Terminal Blocks
Terminal R (L1) is not present on single phase drives. Three phase unit terminal
block configuration is depicted in the figure below.
Drive Terminal Blocks Figure 2.1
ATTENTION: Remove and lock out power from the drive before
you disconnect or reconnect wires or perform service. Verify bus
voltage by measuring the voltage between DC- and DC+ on Terminal
Block TB2. Do not attempt to service the drive until bus voltage has
discharged to zero volts.
ATTENTION: The drive is intended to be commanded by control
input signals that will start and stop the motor. A device that routinely
disconnects then reapplies input power to the drive for the purpose of
starting and stopping the motor should not be used. If it is necessary
to use this method for starting and stopping, or if frequent cycling of
power is unavoidable, make sure that it does not occur more than once
a minute.
ATTENTION: Do not connect power factor correction capacitors to
drive output terminals U, V and W (T1, T2 and T3) or component
damage could occur.
