This equipment should be installed, adjusted, and serviced by qualified elec-
trical maintenance personnel familiar with the construction and operation of
the equipment and the hazards involved. Failure to observe this precaution
could result in bodily injury.
Wiring, maintenance or inspection must be performed by authorized person-
nel. Not doing so may result in electrical shock or fire.
Hazard of electrical shock! Disconnect incoming power before working on the
OMRON 3G3AX-MX2-PRT-E PROFIBUS Option Board or the MX2-A@
Inverter!
Turn the power supply OFF and wait for the time specified on the Option
Board front cover before performing wiring, maintenance or inspection. Not
doing so may result in electrical shock.
The OMRON 3G3AX-MX2-PRT-E PROFIBUS Option Board is attached to an
MX2-A@ Inverter. Dangerous voltage exists until the MX2-A@ Inverter power
light is OFF.
Do not touch the conductive parts such as the internal PCB, terminals or con-
nector while power is being supplied. Doing so may result in electrical shock.
Do not attempt to take an Option Board apart or touch any internal parts while
the power is being supplied. Doing so may result in electric shock.
Do not attempt to disassemble, repair, or modify an Option Board. Any
attempt to do so may result in malfunction, fire, or electric shock.
Provide emergency stop circuits, interlock circuits, limit circuits and similar
safety measures in external circuits (NOT in the Option Board). This ensures
safety in the system if an abnormality occurs due to malfunction of the Option
Board or another external factor affecting the Option Board operation. Not
doing so may result in serious accidents.
Fail-safe measures must be taken by the customer to ensure safety in the
event of incorrect, missing, or abnormal signals caused by broken signal lines,
momentary power interruptions, or other causes. Not doing so may result in
serious accidents.
Do not touch the Inverter during power on, and immediately after power off.
Hot surface may cause injury.
The product will be used to control an adjustable speed drive connected to
high voltage sources and rotating machinery that is inherently dangerous if
not operated safely. Interlock all energy sources, hazardous locations, and
guards in order to restrict the exposure of personnel to hazards. The adjust-
able speed drive may start the motor without warning. Signs on the equipment
installation must be posted to this effect. A familiarity with auto-restart settings
is a requirement when controlling adjustable speed drives. Failure of external
or ancillary components may cause intermittent system operation, i.e., the
system may start the motor without warning or may not stop on command.
Improperly designed or improperly installed system interlocks and permis-
sives may render a motor unable to start or stop on command.
