Preface
Thank you for purchasing our SX bus interface card "OPC-VG1-SX."
The interface card is used to connect our high-performance, vector control FRENIC-VG series of inverters to a
SX-BUS network. Mounting this interface card on your FRENIC-VG allows you to connect the FRENIC-VG to a Fuji
MICREX-SX series of programmable logic controllers and control it as a slave unit using run and speed commands,
and accessing function codes.
This interface card can be connected to D-port of option connection ports on the FRENIC-VG.
This instruction manual does not contain the description of function codes, troubleshooting information, or handling
instructions of the inverter and the MICREX-SX series. Read through this manual in conjunction with the
FRENIC-VG Instruction Manual and User's Manual to become familiar with proper handling and operation. Improper
handling might result in incorrect operation, a short life, or even a failure of the interface card.
Keep this manual in a safe place.

Safety precautions
Read this manual thoroughly before proceeding with installation, connections (wiring), operation, or maintenance
and inspection. Ensure you have sound knowledge of the device and familiarize yourself with all safety information
and precautions before proceeding to operate the inverter.
Safety precautions are classified into the following two categories in this manual.
Failure to heed the information indicated by this symbol may lead to dangerous
conditions, possibly resulting in death or serious bodily injuries.
Failure to heed the information indicated by this symbol may lead to dangerous
conditions, possibly resulting in minor or light bodily injuries and/or substantial property
damage.
Failure to heed the information contained under the CAUTION title can also result in serious consequences. These
safety precautions are of utmost importance and must be observed at all times.
Installation and wiring
• Before starting installation and wiring, turn OFF the power and wait at least five minutes for inverters of 22
kW or below, or at least ten minutes for those of 30 kW or above . Make sure that the LED monitor and
charging lamp are turned OFF. Further, make sure, using a multimeter or a similar instrument, that the DC link
bus voltage between the terminals P(+) and N(-) has dropped to the safe level (+25 VDC or below).
• Qualified electricians should carry out wiring.
Otherwise, an electric shock could occur.
• In general, sheaths of the control signal wires are not specifically designed to withstand a high voltage (i.e.,
reinforced insulation is not applied). Therefore, if a control signal wire comes into direct contact with a live
conductor of the main circuit, the insulation of the sheath might break down, which would expose the signal wire
to a high voltage of the main circuit. Make sure that the control signal wires will not come into contact with live
conductors of the main circuit.
Doing so could cause an accident or an electric shock.
• Do not use the product that is damaged or lacking parts.
Doing so could cause a fire, an accident, or injuries.
