(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. (Note 4) Required User Enable/Disable Interface Circuit is shown on page 3. (Note 5) Valid only with C jumper (JP1) removed. (Note 6) With the inverter powered and JP1 is in place, a ground applied to the enable pin J1-5 will open the inverter fuse. Application Notes: 1) The minimum distance from high voltage areas of the inverter to any conductive material should be .12 inches per kilovolt of starting voltage. 2) Mounting hardware to be non-conductive. 3) Open framed inverters should not be used in applications at altitudes over 10,000 feet. 4) ACreturn should be left floating, not grounded. 5) Contact ERG for possible exceptions.
