ATTENTION: Disconnect and lock out power from
the drive before disassembling the drive. Failure to
disconnect power may result in death or serious injury.
Verify bus voltage by measuring the voltage between
+DC and -DC on Terminal Block TB1. Do not attempt
to service the drive until the bus voltage has discharged
to zero volts.
ATTENTION: Wear a wrist-type grounding strap
when servicing drives. Failure to protect drive
components against ESD may damage drive
components. Refer to “Electrostatic Discharge
Precautions”onpageI-4.
