(7) General instruction
Before starting the operation, each parameter must be
confirmed and adjusted. A failure to do so may cause
some machines to make unexpected motions.
Before starting the operation, the wiring of each
peripheral device must be checked. Faulty wiring may
cause some machines to make unexpected motions.
Any person must stay away from the equipment when the
retry function is set as it will restart suddenly after a trip.
Since pressing the key may not stop the operation
depending on the function setting status, separate circuit
and switch that make an emergency stop (power OFF,
etc.) must be provided.
OFF status of the inverter start signal must be confirmed
before resetting a fault of the converter. If reset is
performed with the start signal ON, the converter starts
suddenly.
The load must be always inverters. Connection of any
other electrical equipment to the converter output may
damage the equipment.
Do not modify the equipment.
Do not perform parts removal which is not instructed in
this manual. Doing so may lead to fault or damage of the
product.
Do not use a magnetic contactor on the power input side
for frequent starting/stopping of the converter or the
inverter. Otherwise the life of the converter or the inverter
decreases.
The effect of electromagnetic interference must be
reduced by using a noise filter or by other means.
Otherwise the electronic equipment used near the
converter or the inverter may be affected.
When parameter clear or all parameter clear is performed,
the required parameters must be set again before starting
operations because all parameters return to the initial
value.
Before running a converter or an inverter which had been
stored for a long period, inspection and test operation
must be performed.
Static electricity in your body must be discharged before you
touch the product. Otherwise the product may be damaged.
A safety backup such as an emergency brake must be
provided to prevent hazardous condition to the machine and
equipment in case of the converter and inverter failure.
When the breaker, which is installed in the input side of
the converter, trips, the wiring must be checked for a fault
(short circuit), and internal parts of the converter and the
inverter for a damage, etc. The cause of the trip must be
identified and removed before turning ON the power of the
breaker.
When any fault occurs, take an appropriate corrective
action, then reset the converter, and resume the
operation.
Do not carry out a megger (insulation resistance) test on
the control circuit of the converter.

CAUTION
The converter must be treated as industrial waste.
Many of the diagrams and drawings in this Instruction
Manual show the converter without a cover or partially open
for explanation. Never operate the converter in this manner.
The cover must be always reinstalled and the instruction in
this Instruction Manual must be followed when operating
the converter.
