the ground connection to a grounding bar or to the general grounding
point (resistance
≤
10 ohms).
DANGER!
The AC input for the Soft-Starter SSW-07 must have a ground
connection.

Do not use the neutral conductor for grounding purpose. Use
dedicated ground conductor.

Do not share the ground wiring with other equipment that operate with
high current (for examples: high voltage motors, welding machines,
etc.). When several Soft-Starters SSW-07 are used, observe the
