Specifications
AC INPUT: 3 position terminal block in High Voltage barrier. Line, Neutral, and Earth Ground
AC Input .......................................................................... ............................... 90-240vac/47-63Hz/220Watts Max
Wide range AC input does not require any selection switching. Earth ground terminal must be properly connected to earth
ground. Note: The Ground connection is connected to the enclosure back with a metal standoff. In the case of
enclosures with a removable lid, a ground wire is used to ensure the ground continuity to the lid. If lid is removed,
this ground wire must be reconnected securely.
AC Fuse Link is inside unit for catastrophic failure. This fuse is not field replaceable, unit must be returned to factory for service should this fuse
blow. A blown fuse is indicated by the AC LED off with AC power applied.
