Document No. DPD01375 Installation Instructions August 24, 2018 NOTE: The overloads are dialed in by the factory, based on the NEC FLA rating tables, and assume a trip (activation) level at 125%. If the 125% is acceptable for your installation, dial in the overload to match the connected motor's FLA rating. If a different percentage is desired, a multiplier must be used to determine the proper setting. This is a twostep process: First, determine the multiplier.
