Power Line Transients; Protection Against Sources Of Electrical Interference - HP StorageWorks XP10000 Disk Array Site Prep Manual

CAUTION:
When installing the receptacles, the electrician must ensure that each receptacle has its
own neutral (if required) and ground. Using the same neutral/ground for more than one
circuit causes voltage loss and heat problems and can create a fire hazard. A shared
neutral conductor that fails open-circuit can cause overvoltage damage to equipment.
See "Chapter 3 Electrical specifications"
and receptacle part numbers and ordering information.

Power line transients

Heavy electrical loads from nearby machinery or equipment (for example, elevators or
electric welders) can cause intermittent system problems with sophisticated electronic
equipment, even if that equipment is on a separate circuit breaker. When faced with
these conditions, provide a separate, completely independent power panel with an
isolated ground and circuit breaker coming directly from the main building power source
or secondary power source.
If necessary, an HP representative can measure your power line noise level and make
appropriate recommendations concerning the use of line treatment devices.
