A screw nut for the grounding of the inverter frame is located next to the power terminals. The grounding screw
is marked with the symbol below:
Connect the inverter to a grounding system in compliance with the regulations in force. To limit disturbance and
radiated interference produced by the inverter, connect the motor ground wire directly to the inverter ground.
The path of the motor ground wire should run parallel to the motor supply cables.
DANGER
Connect the inverter ground terminal to the mains grounding using a wire having
a cross-section equal to or larger than the cross-section of the supply wires, in
compliance with the regulations in force; otherwise, the inverter frame and the
motor casing are exposed to dangerous voltage and electrical shock hazard. The
user has the responsibility to provide a grounding system in compliance with the
safety regulations in force.
NOTE
To fulfil UL conformity requirements of the system where the inverter is installed,
use a “UL R/C” or “UL Listed” lug to connect the inverter to the grounding system.
Use a loop lug fitting the ground screw and having the same cross-section as the
ground cable being used.
