Grounding Requirements
NOTE: A proper and effective building ground connection is required for the safe and successful
operation of the controller.
Examples of a proper building-to-controller ground are as follows:
1. Attach the ground wire to the street side of a water main.
2. Attach the ground wire to a grounding rod in the pit.
The controller has a common ground bus terminal connection.

• The building, motor, transformer, and filter(s) must all share a common ground. This
removes ground loops, limits impedance, and routes noise into the ground.
Wiring
A checklist must be completed during the soft starter wiring process. See Appendix 3 for
terminal location.
Power
Perform the following to connect power. See Set and verify the equipment matches the job
specific parameters for proper operation. See the Hydro:Evolved sheet 7 for job specific
information.
• Connect main line power L1/L2/L3 to soft starter.
• Connect the ground wire to the green terminal screw on the soft starter mounting plate
or ground bus terminal.
