NOTE 1: Use of an external filter is required to comply with conducted emissions limits for load
terminals. For 230 Vac or less, use Watlow P/N 14-0019 or Crydom P/N 1F25 filters. For voltages
up to 440 Vac use Watlow P/N 14-0020 or Crydom P/N 3F20 filters. A Line Impedance Stabilization
Network (LISN) was used for conducted emissions measurements.

NOTE 2: To comply with flicker requirements cycle time may need to be greater than 175
seconds if Load Power is
≤
16A to comply with standard, or the maximum source impedance
needs to be determined. Source impedance shall meet EN 61000-3-11 requirements for load
currents > 16A. Control module power complies with 61000-3-3 requirements.
