The AC input power should be assembled with disconnector(e.g. when
the current is bigger than 1A, the disconnector should be operated).
Make sure connect the live wire to L1 and connect the neutral wire to N,
otherwise the precision of CT will be affected.
2.2 DC Input Port
The DC Input port connects power through the 16V DC power line.
2.3 RJ45 Ethernet Network Port
The ECU-C allows the user to communicate with the EMA, or log in to the
ECU-C's local page in the absence of the wired LAN and WLAN, to set up
the system and view the system data via Ethernet network port.
Ethernet cable connection is recommended for stable communication.
2.4 RJ45 Signal
（
Only for Australia
）
The RJ45 Signal is designed for DRM0/5/6/7/8, it should be connected by
RJ45 connector in the package otherwise the inverters will not work.
Please do not plug out the RJ45.
