Installation Sequence
The following section illustrates the MD-12HD model. The MD-48HD components are slightly different,
but follow the same procedure.
STEP 1. Remove top cover screws (4x) and high voltage cover screws (2x) – provided.
STEP 2. Locate, mark, and drill wall mounting points (2x–6x—customer supplied).
The plastic enclosure itself can be used as a template for marking the drill locations on the wall.
#8 Fastener
If the meter is not available for use as a drill template, a drawing indicating the spacing between mounting
holes can be found in the appendix. The centerline holes are intended for fastening to wall studs. If hollow
wall fasteners are used, the outer 4 mounting points are recommended.
