Safety Precautions
!
ATTENTION: Some printed circuit boards and drive
components may contain hazardous voltage levels.
Remove and lock out power before you disconnect or
reconnect wires, and before you remove or replace fuses
and circuit boards. 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: This assembly contains parts and sub-
assemblies that are sensitive to electrostatic discharge.
Static control precautions are required when servicing this
assembly. Component damage may result if you ignore
electrostatic discharge control procedures. If you are not
familiar with static control procedures, reference Allen-
Bradley Publication 8000-4.5.2 Guarding Against
Electrostatic Damage, or any other applicable ESD
protection handbook.
