C.4 EMS kit installation procedure
The EMS kit must be installed inside the main electrical panel for
metering of the home loads. The energy meter supplied as part of the
EMS kit must be installed and configured according to the electrical
service; supporting both single phase or three phase installations.
Note: Refer to the electrical single line diagram in section C.3 for a
complete signal wiring diagram of the EMS, ESS, and energy meter
connections. The following wiring termination steps assumes the
electrical wiring has been installed.
5.
Mount the EMS kit inside the electrical panel.
6.
Connect the USB to Ethernet adapter to
the Modbus TCP/IP Port of the EMS as
shown in figure 35.
7.
Connect the #3516 cable to the RJ-45
port of the PCS USB to Ethernet
adapter.
8.
Connect the #3516 cable to the PCS
TCP/IP port of the ESS as shown in
figure 34.
11.
EMS: Connect the RJ-45 end of the #3414 cable to the 485 adapter as
shown in figure 34.
12.
Meter: Terminate the pigtail end of the #3414 cable to the RS-485 port of
the energy meter as shown in the table below.

Connect a #3424 cable from the “Main” port of the EMS to the 485 adapter adjacent to the energy meter as shown in
figure 34.
14.
Connect the 12V adapter to the micro USB port of the EMS as
shown in figure 18, and plug the adapter into an electrical outlet.
15.
Ground the DIN rail terminal block to a suitable ground connection
within the electrical panel.
16.
Refer to section C.7 for a power wiring block diagram of the energy
meter. Consult the manufacturer’s meter installation manual for
more details if required.
C.5 EMS Ethernet connection
A permanent ethernet connection is required for an internet
communication from the EMS. The Ethernet wiring from the EMS must be
connected to a customer supplied router (see EMS ethernet port - figure
36).
A 10 meter CAT-5 patch cable (#3516) is included with this system.
