5.0 Meter Installation
5.1 Mounting the E-Mon Green Class Net Meter
STEP 1: Using the appropriate sized mounting hardware, fasten the enclosure to
the selected mounting surface. The four housing mounting holes are
centered 6.75” H x 4” W. The mounting hole spacing is idential for either
the NEMA 4X or NEMA 12/13 enclosures.
NOTE: Only the NEMA 4X enclosed unit is suitable for outdoor
environmental conditions. Units housed in NEMA 12/13 enclosure
units must only be installed in indoor environments where it will not
be affected by the elements.
5.2 Main Power Board Connections
STEP 1: Installing a temporary ground for ESD protection.
With all circuits de-energized, connect a temporary protective earth
ground connection for ESD protection. Prior to performing any unit
wiring, be sure to discharge any static on your person.
STEP 2: Installing the Green Class Net Meter protective earth ground.
Connect an earth ground wire to the meter protective earth ground
terminal screw located on the bottom right side of the main power PCB.
After installing the protective earth ground wire, securely fasten the
protective earth ground screw.
WARNING: Failure to attach the protective earth ground wire securely to the
enclosure creates a potential shock hazard. Do not operate the meter
without a protective earth ground connection securely installed.
STEP 3: Wire Entry
Two openings exist on the unit enclosure; one for 1/2” conduit and one for
3/4” conduit. The 3/4” conduit opening located on the bottom edge of
the housing is used to bring in MAINS power and current sensor wiring.
The 1/2” conduit opening is located on the top edge of the housing and
is used to interface the optional modem telephone line, low voltage
signals, and RS485 communication wiring to the unit. Route the
appropriate cabling to and through the respective enclosure
opening. Outdoor applications require the use of the NEMA 4X
enclosure. The conduit and fi ttings interfacing the enclosure entrances
must be UL listed, properly sized to the enclosure port diameter, and
rated for outdoor use. The interfacing fi tting must use a gasketed seal
ring to interface between the conduit fi tting and the enclosure entry
point. After installing the conduit fi tting and conduit, verify the conduit
fi ttings are aligned properly to their respective enclosure entrance ports
and tightened securely to prevent moisture entry. VERIFY each conduit
slip nut is securely tightened to its respective conduit fi tting.
