Preface
This instruction manual has been prepared to help you connect your FRENIC-MEGA, FRENIC-HVAC or
FRENIC-HVAC-P inverter to Industrial Ethernet networks using the OPC-PRT2 Multiprotocol Ethernet
interface card. This instruction manual does not contain inverter usage instructions. Please refer to this
instruction manual in conjunction with the applicable inverter instruction manual in order to become
familiar with the proper handling, installation and operation of this product. Improper handling or
installation procedures may result in incorrect operation or premature product failure.

Safety precautions
Please read this instruction manual thoroughly prior to proceeding with installation, connections,
operation, or maintenance and inspection. Additionally, ensure that all aspects of the system are fully
understood, and familiarize yourself with all safety information and precautions before operating the
inverter.
Safety precautions in this instruction manual are classified into the following two categories:
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.
Security information
Fuji provides products and solutions that support the operation of plants, systems, machines and
networks. In order to protect these critical assets against cyber threats, it is necessary to implement and
continuously maintain a holistic, state-of-the-art industrial security concept. Fuji’s products and solutions
comprise only one element of such a concept.
Customers are solely responsible for preventing unauthorized access to their plants, systems, machines
and networks. Systems, machines and components should be connected to the enterprise network or
the internet only if appropriate security measures (such as the use of firewalls and network
segmentation) are employed to the extent necessary.
Fuji’s products and solutions undergo continuous development to make them more secure. Fuji strongly
recommends the application of product updates as soon as they are available. The use of product
versions that are no longer supported, and the failure to apply the latest available updates may increase
the customer’s exposure to cyber threats.

Installation and wiring
•To avoid electrical shock, remove all power from the inverter and wait at least five minutes prior to
starting installation. Additionally, confirm that the DC link bus voltage as measured between the P
(+) and N (-) terminals is less than 25 VDC.
•Installation should be performed only by qualified personnel.
•To avoid electrical shock, do not operate the inverter with the front cover or wiring cover removed,
as accidental contact with exposed high-voltage terminals and internal components may occur.
•To prevent explosions or similar damage, ensure that all cables are properly connected to the
correct terminals, and observe all wiring polarity indicators.
•Do not install or operate the interface if it is damaged or has parts missing.
•Prevent conductive items such as screws and metal fragments, or flammable substances such as
oil, lint, paper fibers and sawdust from entering the inverter and interface card enclosure.
•Incorrect handling during installation or removal may cause equipment failure.
•Do not subject the cables to scratches, excessive stress, heavy loads or pinching.
•To prevent damage due to electrostatic discharge, always touch a grounded piece of metal prior
to touching any equipment.
•Do not stand on or rest heavy objects on the equipment.
•To prevent burns from hot components, do not touch the inverter while power is on, or for some
time after power is removed.
•Electrical noise may be emitted from the inverter, motor and wires. Always implement appropriate
countermeasures to prevent nearby sensors and devices from malfunctioning due to such noise.
Operation
•To avoid electrical shock, do not open the front cover of the inverter while power is on or while the
inverter is running.
•To avoid electrical shock, do not operate switches with wet hands.
•If the inverter’s function codes are incorrectly configured, or configured without adequate
understanding of the appropriate inverter Instruction Manual and User's Manual, the motor may
rotate with a torque or at a speed not permitted for the machine. Confirm the settings of all
function codes prior to running the inverter.

Maintenance, inspection, and parts replacement
•To avoid electrical shock, remove all power from the inverter and wait at least five minutes prior to
starting inspection. Additionally, confirm that the DC link bus voltage as measured between the P
(+) and N (-) terminals is less than 25 VDC.
•Maintenance, inspection, and parts replacement should be performed only by qualified personnel.
•Remove all watches, rings and other metallic objects prior to starting work.
•To avoid electrical shock or other injuries, always use insulated tools.
Disposal
•Contact the local or state environmental agency in your area for details on the disposal of
electrical components and packaging.
Other
•Do not attempt to modify the equipment: doing so may cause electrical shock or injuries.
•For clarity purposes, illustrations in this manual may be drawn with covers or safety guards
removed. Ensure all covers and safety guards are properly installed prior to starting operation.
•Do not perform hi-pot tests on the equipment.
•Performing a data initialization (function code H03) may reset all inverter function codes to their
factory default settings. After performing this operation, remember to reenter any custom function
code values prior to starting operation.
