## Compatibility & Integration

AC input voltage is field-configurable; refer to the specific unit and manual for your voltage setting and corresponding fuse rating. Power delivery uses a 3-core cable with designated Line, Neutral, and Ground conductors. Units configured for 125V AC or higher input may be supplied with the AC plug detached; installation of a suitable plug is required before operation.
