3.0 Safety Label Defi nitions and Information The E-Mon D-Mon® Green Class Net Meter may contain one or more of the follow- ing labels. Operator(s) should familiarize themselves with the meaning of each label to minimize risk. The presence of-this label is a cautionary indicator identifying a danger risk. The manual should be consulted prior to proceeding.
Warning: Failure to ground the enclosure creates a possible shock hazard. Do not operate the E-Mon D-Mon® Green Class Net Meter without a protective earth wire attached securely to the PE terminal screw. After installing Protective Earth wiring, secure the screw tightly (10 N-m Torque).
5.0 Meter Installation 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.

STEP 3: Wire Entry (continued) Indoor application units are installed in the metallic NEMA 12/13 enclosures. The same principals outlined for the outdoor meter installation as defi ned in the aforementioned paragraph carry over and apply to indoor installations with one exception. This one exception is the conduit and fi...

STEP 6: Once the MAINS wiring is complete, close the enclosure front panel and secure the panel to the enclosure using the locking mechanism. Activate the external circuit breaker or equivalent switch to apply AC MAINS power to the unit. The Green Class Net Meter’s display should turn on and begin cycling through its multiple screens.
Current Sensor Installation and Wiring Once the AC voltages have been confi rmed to be within acceptable limits, you are ready to install the current sensors. The main power board contains three header connectors located at the bottom center of the board, TB2, TB3 and TB4.
