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 is to be non-conductive.
3 ) Open framed inverters should not be used in applications at altitudes over 10,000 feet.
4 ) Contact ERG for possible exceptions.

(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 cont act ERG technical support.
