Voltage Range Verification of Receptacle

This measures the voltage between L1 and L2, L1 to ground, and L2 to ground. Three separate

measurements are performed during this procedure. Refer to Figure 2-21 for voltage reference

points when performing the following measurements.

Figure 2-21 Voltage Reference Points for IEC-320 C19 Plug

IMPORTANT These measurements must be performed for every power cord that plugs into the HP

Integrity rx8620 Server.

Step 1. Measure the voltage between L1 and L2. This is considered to be a phase-to-phase measurement in

North America. In Europe and certain parts of Asia-Pacific, this measurement is referred to as a

phase-to-neutral measurement. The expected voltage should be between 200–240 VAC regardless

of the geographic region.

Step 2. Measure the voltage between L1 and ground. In North America, verify this voltage is between

100–120 VAC. In Europe and certain parts of Asia-Pacific, verify this voltage is between

200–240 VAC.

Step 3. Measure the voltage between L2 and ground. In North America, verify this voltage is between

100–120 VAC. In Europe and certain parts of Asia-Pacific, verify this voltage is 0 (zero) VAC.

Table 2-6 provides single phase voltage measurement examples dependent on the geographic region where

these measurements are taken.
