2.
All ground circuits must be treated with care.
ground should, via the shortest route, provide a dedicated safety/logic
ground path for termination only to an earth ground stake or dedicated
ground grid. If possible, the ground circuit should not be terminated (1)
anywhere into the mainline AC neutral, because very large hostile
currents, such as RF and large AC neutral leakage, noise spikes,
lightning strike currents, etc., are possible, (2) into any shared grounds,
such as star grounds and ground farms, because of possible hostile
currents, RF spikes, noise, etc., which are electrical pollutants from
host systems using such grounds, and (3) into any grounding media of
questionable quality, such as water pipes, building "I" beams, or
conduit pipes.
The ultimate goal of any equipment grounding is to ensure personnel
safety without sacrificing the stability of reference. To be effective,
grounding must be low impedance at all frequencies.

An ideal ground plane would be a zero-potential, zero-impedance
system that could be used as a reference for all signals in the
associated circuitry.

Storage Procedures.
All Diamond Electronics equipment should be stored in its original shipping
container. These containers facilitate storage for indefinite periods of time,
providing that the external environment can be kept within the general
environmental limits of the equipment itself.

°C (-67 °F) to +85 °C (+185 °F). Humidity must not exceed 95%. Equipment
