Step 2 Ground Connection
Install the ground connection for the inverter.
Locate the ground terminal and connect an appropriately rated ground cable to the terminals. Refer to
1.5 Cable Selection on page 14 to find the appropriate cable specification for your installation.
240V: 7.5 HP ~ 25 HP (5.5 kW ~ 18.5 kW) 240V: 30 HP ~ 60 HP (22 kW ~ 45 kW)
480V: 7.5 HP ~ 40 HP (5.5 kW ~ 30 kW) 480V, 575V: 50 HP ~ 125 HP (37 kW ~ 90 kW)
240V: 75 HP ~ 125 HP (55kW ~ 90 kW)
480V: 150 HP ~ 300 HP (110 kW ~ 185 kW) 480V: 400 HP ~ 800 HP (250 kW ~ 500 kW)
Connect the other ends of the ground cables to the supply ground terminal.
Note
•
240 V products require Class 3 grounding. Resistance to ground must be ≤ 100 Ω.
•
480V/575V products require Special Class 3 grounding. Resistance to ground must be ≤ 10 Ω.
Install ground connections for the inverter and the motor by following the correct specifications to
ensure safe and accurate operation. Using the inverter and the motor without the specified
grounding connections may result in electric shock.
This product can cause a D.C current in the ground conductor. If a ground fault device (RCD or
monitoring RCM) is used for protection, only Type B is allowed on supply side of this product.
