1. See “Noise Emission Notes” on page 336 for definitions of noise emissions positions.
2. The amount of space needed by the unit during normal operation is indicated by the footprint dimensions.
3. Inrush currents occur only at initial application of power, no inrush occurs during a normal power off-on cycle.
