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 4-4 for voltage reference points
when performing the following measurements.

IMPORTANT These measurements must be performed for every power cord that plugs into the HP
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 measured should be between 200–240V AC
regardless of the geographic region.
Step 2. Measure the voltage between L1 and ground. In North America, verify this voltage is between
100–120V AC. In Europe and certain parts of Asia-Pacific, verify this voltage is between 200–240V
AC.
Step 3. Measure the voltage between L2 and ground. In North America, verify this voltage is between
100–120V AC. In Europe and certain parts of Asia-Pacific, verify this voltage is 0 (zero) V AC.
Table 4-1 provides single phase voltage measurement examples dependent on the geographic region where
these measurements are taken.
