H-SERIES GREEN CLASS NET METER
15 62-0424-02
Failure to attach the protective earth ground wire securely to the meter creates
a potential shock hazard. Do not operate the meter without a protective earth
ground connection securely installed.
3. Wire Entry: One 3/4” conduit opening is located on the bottom of the unit enclo-
sure. This opening is used for bringing in MAINS power and for current sensor
wiring. Route the appropriate cabling to and through the respective enclosure
opening.
4. After installing the conduit fitting and conduit, verify that each conduit slip nut is
securely tightened to its respective conduit fitting. Any unused openings must be
sealed with a UL rated plugging device suitable for the rating of the enclosure
(check formatting).
NOTE: Metallic enclosure has one additional 1/2” conduit opening at top of unit.
5. Unit MAINS wiring: The first four positions of terminal block TB1, located at the
bottom left corner of the main power board, are clearly labeled Phase A, B, C, N
(neutral). Earth Ground MUST be connected to the PCB mounting screw in the
lower right corner.
NOTE: For 3-wire delta-type meters, Do NOT connect the NEUTRAL wire. Remove
the terminal block screw for this position. Connect the earth ground to the
PCB mounting screw in the lower right corner.
a. Connect the NEUTRAL wire to the appropriate terminal block position.

b. External Switch Mechanism/In-Line Fuse Installation
c. To ensure a safe installation, the Green Class Net meter requires an external
switch mechanism, such as a circuit breaker, be installed on the Green Class
Net meter MAINS input wiring. The switch mechanism must be installed in
close proximity to the meter and easily reachable for the operator. This
device must also be marked as the disconnecting device for the Green Class
Net meter. Install 1/10 Amp Slow Activation in-line fuses with the suitable
voltage rating for each conductor phase at the MAINS input to the meter. The
fuses must be labeled to indicate voltage and current rating as well as ele-
ment characteristics. The fuse element must be slow activating type.
