• 300 ft. between Communications Gateway and the<br />
network port<br />
• 120 ft. between the monitoring enclosure and location of CTs<br />
and voltage taps<br />
To ensure that your view is ready on time, send a completed<br />
auto-registration to Engenuity at least two days prior to<br />
installation. You can either fill out and return the enclosed autoregistration<br />
documentation, or use the online version.<br />
• This procedure references Elkor meter components described<br />
in the Elkor WattsOn Universal Power Transducer User<br />
Manual. Adhere to all cautions and safety instructions in<br />
applicable Elkor documentation.<br />
• For guidelines about voltage sense line connections on non<br />
screw-type contact, use the Engenuity Technical Note<br />
entitled Using Spring Cage Terminal Blocks.<br />
Because most installation issues relate to network connectivity,<br />
be sure to verify that Internet connectivity is available at the<br />
installation site before you begin this installation. If possible,<br />
verify that the Internet connection works with a laptop and the<br />
Fat Spaniel cgConfig Diagnostic Tool.<br />
Prior to installation, ensure that power to the PV system and the monitored<br />
building circuit is SHUT DOWN.<br />
If the power cannot be shut down, contact Engenuity <strong>System</strong>s Customer<br />
Service at 1-480-782-5600 for additional instructions.<br />
INSTALL ENGENUITY SYSTEMS eBOXX SOLUTION<br />
1. Mount the Communications Gateway<br />
The monitoring system ships inside the outdoor-rated eBOXX enclosure.<br />
Engenuity recommends that a certified electrician be assigned to install the enclosure.<br />
NOTE: You must use appropriate conduit fittings to preserve the NEMA rating and<br />
your warranty.<br />
NOTE: Check the dip switches on the TB25 to ensure that DIP switch settings<br />
are positioned as follows: 2 and 3 = OFF, 1 = ON.<br />
Leads may be at line voltage.<br />

2. Set up the Data Connection<br />
If your meter is in the same enclosure as the Communication Gateway,<br />
the data connection is prewired. If, however, you have additional meters or other<br />
Modbus devices outside the gateway enclosure, these must be daisy-chained.<br />
The wires used in testing your system are left in the appropriate terminals as<br />
connection markers. Refer to the table below.<br />

4 GND<br />
• To connect to the LAN (if you are not using the modem option) connect the<br />
network cable to the LAN1 port on the Communications Gateway.<br />
3. Connect Voltage Sense and Instrument Power Conductors<br />
a. Install a circuit breaker in the load panel and run voltage taps in conduit to the<br />
monitoring enclosure.<br />
b. Connect your voltage taps to the fused voltage blocks in your monitoring<br />
assembly. Your system may be built with a second set of L1 and N voltage<br />
blocks. These are for instrument power, which you may take from the monitored<br />
circuit or from a separate circuit of 120, 208, 230, or 240 VAC.<br />
c. Be sure to attach a ground to the labeled spring clip terminal. The system must be<br />
grounded for both accuracy and safety.<br />
4. Connect the Current Transducers<br />
a. Wire the CT leads directly to the Elkor meter,<br />
matching the wire number to the corresponding<br />
number on the meter.<br />
b. Note the polarity arrow on your CT, and install<br />
the CTs per the attached wiring diagram:<br />
• For PV <strong>Installation</strong>:<br />
The CT polarity indicator must face toward<br />
the inverter.<br />
• For Building Demand <strong>Installation</strong><br />
The CT polarity indicator must face toward<br />
the utility meter.<br />

5. Power Up the Enclosure: Connect AC Power Source<br />
Turn on the instrument power circuit. Check for the green power light on the<br />
24VDC transformer, and the red power LED on the Communications Gateway.<br />
6. Check the Power LED on the Elkor Meter: Look for Green PWR LED.<br />
7. Power Up the Communications Gateway and Check LEDs<br />

8. Power Up the Voltage Sensors<br />
If you have not done so with the instrument power, energize the circuit for the<br />
voltage taps.<br />
9. Check Data Connectivity<br />
If you have a laptop and the Fat Spaniel cgConfig Diagnostic Tool, verify that the<br />
Communications Gateway can connect and that the monitoring devices are visible<br />
to the Communications Gateway.<br />
10. Log into Solar Plant Vision (SPV) under Assets tab to confirm installation<br />
of Logger(s) and Device(s).<br />
