INSTALL MOUNTING RAILS ON WALL:
Establish the required height of the centerline of the bottom
meter socket, per the utility company specifications.
Determine the bottom line of the meter modules and main
devices. Use a "Z" dimension per the table below. That
is the distance from the bottom meter socket line to the
bottom of a meter module.
Measure up a distance "X" (see table) inches from the
bottom line of the meter modules to mounting holes for the
mounting rail. Strike a level line for the fasteners and attach
the mounting rails. (See Fig. 1 below).

and main devices have four mounting feet). After marking
holes on the wall, the mounting feet may be moved away
for drilling of the holes. (See Fig. 1 below).
METER SOCKET COVERS:
Remove all the meter socket covers which are over the
horizontal main bus. Ring style covers are attached with
two screws inside the socket rim. Ringless style covers
are attached with an external movable latch. (See Fig. 2).
Ringless style covers have barrel lock provision K.O. To
