Preface

Thank you for purchasing our digital interface option. Mounting the digital interface option on your FRENIC-Multi makes it possible to specify frequency commands with binary code ( 8 or 12

bits) or BCD (4-bit Binary Coded Decimal) code. It also enables monitoring with 8-bit binary code. This instruction manual does not contain inverter handling instructions. Read through this instruction manual in conjunction with the

FRENIC-Multi Instruction Manual and be familiar with proper handling and operation of this product. Improper handling might result in incorrect operation, a short life, or even a failure of this product.

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 the inverter's power OFF and wait at least five minutes. Further, check with a multimeter or the similar instrument that the DC link bus voltage between the P (+) and N (-) terminals is lower than 25 VDC.

• Qualified electricians should carry out wiring.

Otherwise, an electric shock could occur.

• Do not use the product that is damaged or lacking parts.

Doing so could cause a fire, an accident, or injuries.

• Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the inverter and the option.

Otherwise, a fire or an accident might result.

• Incorrect handling in installation/removal jobs could cause a failure.

A failure might result.

• Noise may be emitted from the inverter, motor and wires. Implement appropriate measure to prevent the nearby sensors and devices from malfunctioning due to such noise.

Otherwise, an accident could occur.

Operation

• Be sure to install the terminal cover and option terminal cover before turning the inverter's power ON. Do not remove the cover when the inverter power is ON.

Otherwise, an electric shock could occur.

• Do not operate switches with wet hands.

Doing so could cause an electric shock.

• If you set the function codes wrongly or without completely understanding the FRENIC-Multi Instruction Manual and the FRENIC-Multi User's Manual, the motor may rotate with a torque or at a speed not permitted for the machine. C onfirm and adjust the setting of the function codes before running the inverter.

Otherwise, an accident could occur.

Maintenance and inspection, and parts replacement

• Before proceeding to the maintenance/inspec tion jobs, turn the inverter's power OFF and wait at least five minutes. Further, check with a multimeter or the similar instrument that the DC link bus voltage between the P (+) and N (-) terminals is lower than 25 VDC.

Otherwise, an electric shock could occur.

• Maintenance, inspection, and parts replacement should be made only by qualified persons.

• Take off the watch, rings and other metallic objects before starting work.

• Use insulated tools.

Otherwise, an electric shock or injuries could occur.

Disposal

• Treat the interface card(s) as an industrial waste when disposing of it.

Otherwise injuries could occur.

Others

• Never modify the interface option(s).

Doing so could cause an electric shock or injuries.

Chapter 1 BEFORE USING THE INVERTER

1.1 Acceptance Inspection

Unpack the package and check the following: (1) A digital interface option and the following accessories are contained in the package. (See Figure 1.1.)

- Two option connection cables (A short one for inverters with a capacity of 5 HP or below and a long one for inverters with a capacity of 7.5 HP or above)

- One option fixing screw

- Digital Interface Option Instruction Manual (this manual)

(2) The interface option and accessories have not been damaged during transportation—there should be no dents or parts missing. (3) The model name "OPC-E1-DIO" is printed on the nameplate attached to the right side of the interface option. (See Figure 1.1.)

If you suspect the product is not working properly or if you have any questions about your product, contact your Fuji Electric representative.

1.2 Installation of the Interface Option

Turn the inverter's power OFF and wait for at least five minutes. Further, check that the DC link bus voltage between the P (+) and N (-) terminals is lower than 25 VDC.

Otherwise, electric shock could occur.

• Do not use the product that is damaged or lacking parts. Doing so could cause a fire, accident, or injury.

• Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the inverter and the interface option.

Otherwise, a fire or an accident might result.

• Incorrect handling in installation/removal jobs could cause a failure.

A failure might result.

When handling the interface option, take any antistatic measure or hold the plastic parts taking care not to directly touch the circuit board; otherwise, the static electricity charged in your body may damage it.
