Introduction
The Allen-Bradley Bulletin 1608M MegaDySC Dynamic Sag Corrector is
engineered to provide years of trouble-free voltage sag (dip) protection. The
patented DySC technology does not use batteries, requires only routine
maintenance, includes three-stage transient voltage surge suppression, and has
unparalleled energy efficiency. Most electronic devices found in industry today
are susceptible to power disturbances. A momentary sag in line voltage can reset
or damage sensitive production equipment. The MegaDySC provides
instantaneous dynamic sag correction to help your equipment ride through these
common events. The MegaDySC connects normal utility power directly to the
load until a voltage sag occurs. During a sag, the MegaDySC inverter is activated-
adding missing voltage to keep the load voltage within the normal range. When
utility power returns to normal, the inverter is deactivated and the MegaDySC is
quickly ready to correct the next sag.
The MegaDySC reports these voltage sag events through its integrated touch
screen display and provides system status, voltage sag notification and history,
runtime statistics and system history in a simple and intuitive touch-based user
interface.
Safety Considerations The MegaDySC is designed to operate in industrial applications. Follow these
guidelines to ensure that the safety and installation of the MegaDySC are
handled with appropriate care.
SHOCK HAZARD: The MegaDySC has high voltage remaining up to 5 minutes
after disconnection from the AC line. Touching exposed or disconnected
terminals, cables or parts of the MegaDySC can lead to serious injuries or even
death. Wait for a minimum of 5 minutes before performing any service or
testing on the MegaDySC after power is removed. High voltage remains if red
LED indicators above capacitor banks are lighted. Keep the cabinet doors closed
and locked to ensure proper cooling airflow and to protect personnel from
dangerous voltages inside the MegaDySC.
ATTENTION: - To reduce the risk of fire or electric shock, install this MegaDySC
in a temperature and humidity controlled, indoor environment, free of
conductive contaminants.
• Avoid installing the MegaDySC directly near heat-emitting equipment such as ovens, heaters, or
furnaces.
• Ambient temperature must not exceed 40°C (104°F).
• Do not operate near water or excessive humidity (95% max).
• When punching or drilling holes for conduit fittings, take care to avoid dropping metallic particles
inside the enclosure as this can result in electrical damage.
• The system is not intended for outdoor use.
• The operating environment should be maintained within the parameters stated in this manual.
• Only authorized service personnel should perform service on the MegaDySC.
• Ensure all power is disconnected before performing installation or service.
