Remove the front cover(s) and the control terminal cover. Then follow the instructions
below to install the ground connection for the inverter.
1 Locate the ground terminal and connect an appropriately rated ground cable to
the terminals. Refer to 1.5 Cable Selection on page 10 to find the appropriate
cable specification for your installation.
2 Connect the other ends of the ground cables to the supply earth (ground) terminal.
• 200 V products require Class 3 grounding. Resistance to ground must be < 100Ω.
• 400 V products require Special Class 3 grounding. Resistance to ground must be less
than < 10 Ω.
Make sure to install ground connection between the equipment and the motor for safe
use. Otherwise it may cause an electrical shock and result in personal injury or even
death.
