ELECTRONIC ENCLOSURE
The Model 2100 electronics are housed in a rugged,
NEMA 4X rated 7.75" x 5.75" x 4" (W x H X D)
polycarbonate enclosure designed for wall mounting.
Supplied are two 1/4-20 x 3/4 inch mounting screws for
use with lead inserts, two 1/4-20 x 3/4 inch sheet metal
screws for other wall materials and two “O” rings
necessary to maintain the NEMA 4X rating of the
enclosure.

When mounting the Model 2100 electronics, select a
location that has good ventilation, temperature within the
meter's specification, not subject to flooding, protection
from accidental shock and provides for accessibility to
operate and service the meter.

ENCLOSURE MOUNTING
To mount the enclosure use the 5/32 inch Allen wrench
supplied in the mounting hardware package to loosen and
remove all four hex bolts in the front of the housing (see
Figure 2-1). Separate the front and back housings.
CAUTION: THERE IS A COAX SIGNAL WIRE
AND A RIBBON CABLE CONNECTED FROM
THE FRONT HOUSING TO THE POWER SUPPLY
BOARD THAT MUST BE DISCONNECTED WHEN
REMOVING THE FRONT HOUSING (SEE
FIGURE 2-2).
Place the front housing in a protected area
so that it will not be damaged while mounting the back
housing.

To mount the back housing, two holes must be drilled
in the wall 4.5 inches apart (center line to centerline, see
Figure 2-3). The size of the holes will depend on whether
lead inserts are used or the mounting screws are screwed
directly in the wall. Select the appropriate screws and
place the "O" rings on the screws. With a 3/8 inch hex
head driver, secure the back housing to the wall.
Since
the power supply board is in the back housing, care
should be taken to prevent damaging any components
on the board.
