General Precautions – Read These First!
WARNING: This equipment should be installed, adjusted, and serviced by qualified
electrical 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.
WARNING: The user is responsible for ensuring that all driven machinery, drive train
mechanism not supplied by Hitachi Industrial Equipment Systems Co., 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 equipment protection, install a ground leakage type breaker with a fast
response circuit capable of handling large currents. The ground fault protection circuit
is not designed to protect against personal injury.
WARNING: HAZARDOUS OF ELECTRICAL SHOCK. DISCONNECT INCOMING
POWER BEFORE WORKING ON THIS CONTROL.
WARNING: Wait at least five (5) minutes after turning OFF the input power supply
before performing maintenance or an inspection. Otherwise, there is the danger of
electric shock.
CAUTION: These instructions should be read and clearly understood before working on
WJ200 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 Hitachi Industrial
Equipment Systems Co., Ltd.
CAUTION: Be sure to connect a motor thermal disconnect switch or overload device to
the WJ200 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 five
(5) minutes 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.
