5.1.4 Safety Precautions
***** WARNING *****
The MX28B 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. 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 be wrapped in electrical tape or otherwise insulated.
5.1.5 Room/Locations
NOTE: The Advance Power, Inc. Model MX28B dc power plant is to be installed in a
room, vault, or similar enclosure that is accessible only to qualified persons in
accordance with the NEC or the authority having jurisdiction.
Prior to installation, drawings, floor loading requirements, external alarm points, ac service
entrance, and grounding schemes should all be checked and confirmed. If batteries are to
be mounted in a room separate from the power plant, careful attention should be paid to
battery cable voltage drop effects. Environmental operating temperatures and
ventilation/cooling considerations should also be noted, not just for the power system but for
all other equipment that may reside in the power room area.
