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.

2 INSTALLATION
2.1 Pre-Installation Instructions
•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.
•Only one additional option card may be used when the OPC-PRT3 is installed in the inverter. If
two additional option cards are required, please consult with the factory first to confirm
compatibility.
2.2 Installation Procedure for FRENIC-MEGA, FRENIC-HVAC, FRENIC-HVAC-P,
FRENIC-AQUA, non-Ace Inverters
Before installing the interface card, perform all wiring for the main circuit terminals and
control circuit terminals.
1. Remove the front cover from the inverter to expose the control printed circuit board (control PCB).
As shown in Figure 4, there are three option connection ports (A-port, B-port and C-port). The
card is mechanically keyed for, and can only be installed into, the A-port (bottom-most) position.
To remove the front cover, refer to the applicable inverter Instruction Manual.

2. Rest the left-hand side of the interface card on the control PCB’s A-port mounting support. Align
the positioning notch on the interface card with the A-port positioning key, and then slide the
interface card to the left to engage the key into the notch. Refer to step in Figure 5.
3. Rotate the right-hand side of the interface card downward to engage connector CN1 (on the back
of the interface card) into the A-port connector (CN4) on the inverter’s control PCB. Ensure that
the connectors are fully engaged. Refer to step in Figure 5.
Ensure that the interface card is fully aligned and seated into the communication
port and be sure to perform steps and in the proper order. Failure to do so
may lead to insufficient connector insertion and result in contact failure.

4. Secure the interface card to the connector board PCB by first tightening the included M3 x 6mm
screw into the inverter standoff located at the lower-right hand corner of the interface card. Next,
install and tighten the included M3 x 6mm screw into the standoff mounting hole located at the
upper-left hand corner of the interface card. Refer to Figure 6.

5. Connect the network cables as necessary. Insert the Ethernet cables into the Ethernet jacks,
making sure that they are fully seated. Ensure that the cables are routed in such a way that they
will not be pinched and are not located near any power-carrying wiring, such as the inverter’s input
power or motor wires.
6. Reinstall all covers removed in step 1. Take a moment to confirm that the Ethernet cables are not
being pinched and are not routed near any power-carrying wiring.
For reinstallation instructions, refer to the applicable inverter Instruction Manual.
