4 Rectifiers
596 Series A and D
Overview The 596 Series A rectifier (55A) and 596D rectifier (110A) operate from
single-phase ac service with a phase-to-phase voltage within the range
of 176-264Vac.
The rectifiers are shipped separately from the cabinets for quick and
straightforward installation into rectifier shelves at the site.
Interconnections to ac input, dc output, and control signals occur
automatically during insertion. The rectifier is keyed to prevent
installation of the wrong rectifier. No settings or adjustments to
potentiometers are necessary. The installer must set the rectifier’s ID
using the ON/STBY switch to allow the controller to learn the rectifier’s
physical location.
The 596A and D rectifiers are UL Recognized for both the U. S. and
Canada, comply with UL1950 (Information Technology Equipment),
and meet EN60950 requirements.
Front Panel Display
Power Switch This three-position switch has two active states:
• It controls the on/standby state of the rectifier.
• It is used to set the rectifier ID.
Status Indicators In addition to the ON and STBY LEDs, four other LEDs on the
rectifier’s faceplate indicate the rectifier’s condition.
• The ALM LED is red and lights whenever the rectifier fails.
