•For UPS products and PDUs that have permanently attached AC power cords or are directly wired to the building power, the total combined leakage current should not exceed 5 percent of the total input current required for the connected products.

•For UPS products and PDUs that have detachable AC power cords, the total combined leakage current should not exceed 3.5 mA per PDU or UPS.

Power distribution safety grounding (LAHJ)

The power distribution safety grounding system consists of connecting various points in the power distribution system to earth ground using green (green/yellow) wire ground conductors. When tied to metal chassis parts that might be touched, these ground connections protect computer room personnel against shock hazard from current leakage and fault conditions.

Power distribution systems consist of several parts. HP recommends that these parts be solidly interconnected to provide an equipotential ground to all points.

Main building electrical ground

The main electrical service entrance equipment should have an earth ground connection, as required by applicable codes. Connections such as a grounding rod, building steel, or a conductive type cold water service pipe provide an earth ground.

Conduit bonding

Construct all electrical distribution systems of metallic conduit that is connected together securely or bonded to panels and electrical boxes to provide a continuous grounding system.

Power panel ground

Each power panel should be grounded to the electrical service entrance with green (green/yellow) wire ground conductors. The green (green/yellow) wire ground conductors should be sized per applicable codes (based on circuit overcurrent device ratings).

NOTE: The green wire ground conductor can be a black wire with green tape (LAHJ).

Computer safety ground

Ground all computer equipment with the green (green/yellow) wire included in the branch circuitry. The green (green/yellow) wire ground conductors should be connected to the appropriate power panel and should be sized per applicable codes (based on circuit overcurrent device ratings).

Dual power source grounding

With dual power sources, both sources must have the same ground reference. Otherwise, an electrical potential could exist that could be hazardous to personnel and might cause performance issues for the equipment.

Because the dual power sources often originate from two different transformers or two different UPS devices, use the same ground reference point to ground the secondary of each transformer or UPS device. Measure the voltage potentials from ground pin to ground pin of these sources. Voltage levels that are
