c. Outdoor applications require the use of the optional 4X enclosure. The same
principles outlined for indoor meter installations as defined in the aforemen-
tioned paragraph carry over and apply to outdoor installations with one
exception. This exception is that the conduit and fittings for outdoor installa-
tions require an outdoor material rating and approval for 4X applications.
4. Unit MAINS Wiring (Voltage Wiring Connections)
a. Remove the shield located over the phase A,B and C screw terminals on the
main power board. This shield can be removed by pulling back on the latch
on the right side of the shield and lifting up on the front. Wire each connec-
tion to the terminal block with stranded wire 14-12 AWG, rated at 600 VAC.
b. Strip back all wire insulation to expose between 1/4” and 3/8” of the copper
conductors. Gently twist each wire to prevent fraying. Insert the conductors
into their respective terminal block position and tighten down the terminal
block screw to securely fasten the conductor. The terminal block is clearly
labeled PHASE A, PHASE B, PHASE C and NEUTRAL.
c. Connect the NEUTRAL wire to the appropriate terminal block position.
NOTE: For Delta MAINS input wiring, DO NOT connect the NEUTRAL wire. Remove
the terminal block screw for this position.
d. Connect the AC mains power wires (Phase A, Phase B and Phase C) to their
respective positions as labeled on terminal block.Tighten the screws to 7 in-
lb of torque.
e. After all conductors are connected to their respective terminal block positions
and tightened down, verify that each terminal block screw is securely fas-
tened by gently tugging on each conductor. Verify no conductor wires are
frayed or are shorting to adjacent terminal block positions.
5. External Switch Mechanism/In-Line Fuse Installation
a. To ensure a safe installation, the Green Class meter requires an external
switch mechanism, such as a circuit breaker, be installed on the Green Class
MAINS input wiring. The switch mechanism must be installed in close prox-
imity to the meter and easily reachable for the operator. This device must
also be marked as the disconnecting device for the Green Class meter.
b. 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 element charac-
teristics. The fuse element must be slow activating type.
6. Once the MAINS wiring is complete, replace the clear Lexan protective shield
over terminal block TB1 and close the enclosure front panel. Secure the enclo-
sure cover using the locking mechanism. Activate the external circuit breaker or
equivalent switch to apply AC MAINS power to the unit.
7. The Green Class meter display should turn on and indicate total kWh accumula-
tion reading.
NOTE: On demand meters the unit display, clock and other critical configuration
parameters will be reset once the unit installation and wiring is complete.
