Preface
Thank you for purchasing our digital interface card(s).
This instruction manual describes the digital input interface card "OPC-G1-DI" and the digital output interface
card "OPC-G1-DO" designed for the FRENIC-MEGA series of inverters. For descriptions of the former, refer to
Chapter 2 "DIGITAL INPUT INTERFACE CARD"; for the latter, refer to Chapter 3 "DIGITAL OUTPUT
INTERFACE CARD." Chapters 1, 4, and 5 are common to both cards.
Mounting the digital input interface card on your FRENIC-MEGA makes it possible to specify frequency
commands with binary code (8, 12, 15, or 16 bits) or BCD (4-bit Binary Coded Decimal) code.
Mounting the digital output interface card on your FRENIC-MEGA enables monitoring with 8-bit binary code.
Each of the digital input interface card and the digital output interface card can be connected to any one of the
three option connection ports (A-, B-, and C-ports) on the FRENIC-MEGA. Concurrent use of both cards
provides a digital input/output interface.
This instruction manual does not contain inverter handling instructions. Read through this instruction manual in
conjunction with the FRENIC-MEGA 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.
• Read through this instruction manual and be familiar with the digital interface card(s) before
proceeding with installation, connections (wiring), operation, or maintenance and inspection.
• Improper handling might result in incorrect operation, a short life, or even a failure of this product as
well as the motor.
• Deliver this manual to the end user of this product. Keep this manual in a safe place until this product
is discarded.
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
with a capacity of 22 kW or below, or at least ten minutes for inverters with a capacity 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.
• 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 front 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 configure the function codes wrongly or without completely understanding FRENIC-MEGA
Instruction Manual and the FRENIC-MEGA User's Manual, the motor may rotate with a torque or at a
speed not permitted for the machine. Confirm 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/inspection jobs, turn OFF the power and wait at least five
minutes for inverters with a capacity of 22 kW or below, or at least ten minutes for inverters with a
capacity 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).
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 card(s).
Doing so could cause an electric shock or injuries.
