4.0 METER INSTALLATION
4.1 Mounting the Meter
Using the appropriate sized mounting hardware, fasten the Green Class meter
enclosure to the selected mounting surface. The four mounting holes are centered
6.75” H x 4” W. The mounting hole spacing is identical for either the UL Type 1 or
NEMA 4X enclosure.
NOTE: Only the NEMA 4X enclosed unit is suitable for outdoor environmental condi-
tions. Units housed in UL Type 1 enclosures must only be installed in indoor
environments where it will not be affected by the elements, such as moisture
and extreme temperatures.
4.2 Main Power Board Connections
1. Install a temporary ground for ESD (Electrostatic Discharge) 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.
2. Install the Green Class Protective Earth Ground. Connect an earth ground wire
to the Green Class protective earth ground terminal screw located on the right
side of the line voltage terminal block. After installing the protective earth ground
wire, securely fasten the protective earth ground screw.
WARNING
WARNING: Failure to attach the protective earth ground wire securely to the
enclosure creates a potential shock hazard. Do not operate the Green Class
meter without a protective earth ground connection securely installed.
3. Wire Entry.
a. 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 of the enclosure
is used to bring in MAINS Power (voltage lines to power meter) and current
sensor wiring. The 1/2” conduit opening located on the top of the enclosure
is used to interface low voltage signals, such as the IDR interface and iso-
lated pulse output. (Outdoor enclosures equipped with one 3/4” conduit
opening on bottom of enclosure only.)
b. Route the appropriate cabling to and through the respective enclosure open-
ing. The conduit and fittings interfacing the enclosure entrances must be UL
listed and properly sized to the enclosure port diameter, The interfacing fit-
ting must use a gasket seal ring to interface between the conduit fitting and
the enclosure entry point. After installing the conduit fitting and conduit, verify
that the conduit fittings are aligned properly to their respective enclosure
entrance ports and tightened securely to prevent moisture entry. VERIFY
that each conduit slip nut is securely tightened to its respective conduit fit-
ting.
