5.1.4 Safety Precautions
***** WARNING *****
The MX28B600 DC power plant is supplied from a nominal 220V AC, 60 Hz source. Keep
the AC input enclosure cover in place when the system is operational or energized.
***** WARNING *****
Hazardous energy levels are present on bare conductors in the -48V DC distribution
connection area of the plant. While certain engineering precautions have been designed into
the system, accidental shorting of distribution conductors can cause arcing and high
currents that can cause serious burns or other physical harm.
It is recommended that:
• Any jewelry, rings or watches be removed while working on this equipment.
• Handles of all wrenches, screwdrivers, cutters and pliers be insulated.
• Shafts of screwdrivers must be wrapped in electrical tape or otherwise insulated.
*****WARNING*****
NOTE: OVER TEMPERATURE WILL LEAD TO RECTIFIER SHUTDOWN.
Rectifier fan inlet filters are available for dusty or hostile environments. The filters
require periodic cleaning and/or replacement. Monitor filters to determine a maintenance
cycle for filter cleaning. Rectifiers will signal OVER TEMPERATURE WARNING and
eventually fail if filters are not maintained.
5.1.5 Room/Locations
NOTE: The power plant is designed for installation in a room, vault, or similar enclosure
that is accessible only to qualified persons in accordance with NEC or other
authority having jurisdiction.
