1) Users can customize the length of the CT communication cable. The
accessory package provides 1*RJ45 and 1*waterproof connector with
RJ45 terminals.
When the CT cable is completed, connect the A terminal to the
"CT/METER" port of the inverter and tighten the waterproof screw, and
connect the B terminal to the RJ45 coupler.

B
METER/CT pin is defined as follow:
Ø METER/CT communication cable
Note!
Only one of the Meter and CT connections can be selected.
Meter cable goes to pin terminal 4 and 5; CT-R cable to PIN
Terminal 1 and 8; CT-S cable to PIN Terminal 2 and 7; CT-T cable is
connected to terminals 3 and 6.
