3.2.1 New Power Installation
The power cable must contain a separate earth-ground conductor. When a separate
ground conductor is used, do not connect neutral to ground at either the disconnect or the
display. To do so violates electrical codes and voids the warranty (refer to Figure 1).
3.2.2 Existing Power Installation With No Earth Ground Conductor
When a separate ground conductor is not available, connect the neutral to the earth-ground
at the disconnect, never at the display (refer to Figure 2).
