Grounding Requirements
Because the DecisioNet System connects logic reference ground to
safety ground, a noise-free grounding circuit is necessary for good
system integrity.
Use an isolated ground receptacle, such as a Hubbell IG-5262 or
equivalent. Make sure the ground conductor is insulated from conduit
and neutral wire, and that it is connected to an insulated terminal strip
at the distribution panel. DO NOT use this dedicated insulated ground
wire as a neutral.
DO NOT use a conduit as a ground. Resistance at the conduit joints
may create multiple ground levels within the electrical power
distribution system and degrade the reliability of the DecisioNet
System.
Power Distribution Requirements
Be aware of the following power distribution requirements:
• All wire connections must be electrically and mechanically sound
and protected from deterioration. Deterioration due to corrosion or
electrolysis, especially in humid or corrosive atmospheres, may
result in electrical noise and/or a safety hazard.
• Electrical equipment such as wiring and circuit breakers cause
voltage drops in the power distribution system. Verify that the
voltage at each AC power outlet is within specification.
• Install AC power outlets in locations that are easily accessible and
as close as possible to the equipment they serve.
• Do not route power cords through openings with sharp edges or in
areas where they are exposed to sharp edges or pointy objects.
• Verify that all applicable national, state, and local codes are met.
