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 FRENIC-Mega Instruction Manual (INR-SI47-1457-E) and FRENIC-Mega
User's Manual (MEH642), 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.
