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-PRT 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
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).
Install the interface card according to the inverter capacity as shown in Figure 5, Figure 6, or
Figure 7. Otherwise, refer to the FRENIC-ACE Instruction Manual or contact Fuji for the
appropriate installation instructions.
To remove the front cover, refer to the FRENIC-Ace Instruction Manual, Section 2.2.
