4. Additional Instructions
Also note the following points to prevent an accidental failure, injury, electric shock, etc.
1) Transportation and installation
When carrying products, use correct lifting gear to prevent injury.
Do not stack the inverter option boxes higher than the number recommended.
Ensure that installation position and material can withstand the weight of the inverter.
Do not operate if the power regeneration common converter is damaged or has parts missing.
When carrying the inverter option, do not hold it by the terminal block cover or setting dial; it may fall off or
fail.
Do not stand or rest heavy objects on the inverter option.
Check the inverter option mounting orientation is correct.
Prevent screws, wire fragments, other conductive bodies, oil or other flammable substances from entering
the power regeneration common converter.
Do not drop the power regeneration common converter, or subject it to impact.
Use the inverter option under the following environmental conditions. Using it outside the operating range
can cause the power regeneration common converter to become faulty.

2) Operation
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.
3) Maintenance, inspection and parts replacement
Do not carry out a megger (insulation resistance) test on the control circuit of the power regeneration
common converter unit.
4) Emergency stop
When the breaker on the power regeneration common converter input side trips, check for the wiring fault
(short circuit), damage to internal parts of the power regeneration common converter, etc. Identify the
cause of the trip, then remove the cause and power on the breaker.
5) Disposing of the inverter
Treat as industrial waste
6) General instructions
Many of the diagrams and drawings in this instruction manual show the inverter without a cover, or partially
open. Never operate the inverter in this like. Always replace the cover and follow this instruction manual
when operating the inverter.
