2 General Precautions - Read These First!
!WARNING This equipment must be installed, adjusted, and serviced by qualified electri-
cal maintenance personnel familiar with the construction and operation of the
equipment and the hazards involved. Failure to observe this precaution may
result in bodily injury.
!WARNING The user is responsible to ensure that all driven machinery, drive train mecha-
nism not supplied by OMRON, and process line material are capable of safe
operation at an applied frequency of 150% of the maximum selected fre-
quency range to the AC motor. Failure to do so can result in destruction of
equipment and injury to personnel should a single-point failure occur.
!WARNING For equipment protection, install a ground leakage type breaker with a fast
response circuit capable of handling large currents. The ground fault protec-
tion circuit is not designed to protect against personal injury.
!WARNING HAZARDOUS OF ELECTRICAL SHOCK. DISCONNECT INCOMING
POWER BEFORE CHANGING WIRING, PUT ON OR TAKE OFF OPTIONAL
DEVICES OR REPLACE COOLING FANS.
!WARNING Wait at least ten (10) minutes after turning OFF the input power supply before
performing maintenance or an inspection. Otherwise, there is the danger of
electric shock.
!Caution Make sure to read and clearly understand these instructions before working
on MX2 series equipment.
!Caution Proper grounds, disconnecting devices and other safety devices and their
location are the responsibility of the user and are not provided by OMRON
!Caution Be sure to connect a motor thermal disconnect switch or overload device to
the MX2 series controller to assure that the inverter will shut down in the event
of an overload or an overheated motor.
!HIGH VOLTAGE Dangerous voltage exists until power light is OFF. Wait at least ten (10) min-
utes after input power is disconnected before performing maintenance.
!WARNING This equipment has high leakage current and must be permanently (fixed)
hard-wire to earth ground via two independent cables.
