(Note 1) Surface temperature must not exceed 80 degrees C; thermal management actions may be required. (Note 2) Input current in excess of maximum may indicate a load/inverter mismatch condition, which can result in reduced reliability. Please contact ERG technical support. (Note 3) Provided data is not tested but guaranteed by design. Application Notes: 1) Printed circuit boards to be free of traces beneath the inverter. 2) The minimum distance from high voltage areas of the inverter to any conductive material should be .12 inches per kilovolt of starting voltage. 3) ACreturn should be left floating, not grounded. 4) Contact ERG for possible exceptions. Endicott Research Group, Inc. (ERG) reserves the right to make changes in circuit design and/ or specifications at any time without notice. Accordingly, the reader is cautioned to verify that U L ® data sheets are current before placing orders. Information furnished by ERG is believed to be accurate and reliable.
