WARNING: This equipment should be installed, adjusted and serviced by qualified electrical
maintenance personal familiar with the construction and operation of the equipment
and the hazards involved. Failure to observe this precaution could result in bodily injury.
WARNING :
The user is responsible for ensuring that all driven machinery, drive train
mechanism not supplied by Hitachi, Ltd., and process line material are capable of safe operation
at an applied frequency of 150% of the maximum selected frequency 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 protection, install a leak breaker type with a high frequency circuit capable
of large currents to avoid an unnecessary operation. The ground fault protection circuit is not
designed to protect personal injury.
WARNING :
HAZARD OF ELECTRICAL SHOCK. DISCONNECT INCOMING
POWER BEFORE WORKING ON THIS CONTROL.
AVERTISSEMENT :

WARNING :
SEPARATE MOTOR OVERCURRENT, OVERLOAD AND OVER-
HEATING PROTECTION IS REQUIRED TO BE PROVIDED IN ACCORDANCE
WITH THE SAFETY CODES REQUIRED BY JURISDICTIONAL AUTHORITIES.

CAUTION:
Be sure to connect a motor thermal switch or overload device to the J300 series
controller to assure that the inverter will shut down in the event of an overload or an overheated
motor.
CAUTION:
DANGEROUS VOLTAGE EXISTS UNTIL CHARGE LIGHT IS OFF.
ATTENTION:
PRESENCE DE TENSIONS DANGEREUSES TANT QUE LE VOYANT
N'EST PAS ETEINT.
CAUTION:
Rotating shafts and above ground electrical potentials can be hazardous. There-
fore, it is strongly recommended that all electrical work conform to the National Electrical Codes
and local regulations. Installation, alignment and maintenance should be performed only by
