During the actual operation, please pay attention to the installation of current
transformer as the diagram shows below:
As illustrated above, open the current transformer and you can see an arrow labeled on it
indicating the direction of current. Put the live wire among the under-detection wires
onto the current transformer. After latching the current transformer, the installation has
been finished.
Chart 5.25
Notice:
The direction (from K to L) of the arrow on the current transformer is corresponding to
the direction of the current in live wire from Grid to Load. Sensor needs to be placed in
the power distribution cabinet.

Connection of Meter Terminal
When customer needs to use meter to monitor the energy flow, the meter terminal
connection steps are as follows:
1.Reference 5.2, make LAN cables with RJ45 terminal.
2.Thread the swivel nut over the LAN cable.
3.Press the cable support sleeve out of the cable gland.
4.Remove the filler plug from the cable support sleeve.
5.Route the LAN cable through an opening in the cable support sleeve.
6.Thread the LAN cable through the cable gland.
7.Insert the RJ45 plug of the network cable into the “CT1/METER1” pin connector on the
inverter until it snaps into place.
8.If no other cables need to be installed, lock the waterproof cover to the inverter with
screws.
9.Screw the swivel nut onto the waterproof cover.
Note:
1.Meter and CT can't be installed at same time, please set the sensor model when
selecting CT or electricity meter, please refer to section 6.3.3 for details.
2.Meter must be provided by Jinko. If not, maybe meter can't communicate with JKS
inverter.
3.The more detail describe of meter installation, please turn to meter user manual.
●
The position of export limitation CT or Meter must between the
Inverter & Load and grid.
●
Multiple inverter combination is not suitable in Australia.
●
The smart meter and CT can be used only up to 2000m altitude.
Information
This series inverter has integrated export limitation functionality. To use this function,
you can connect smart meter or CT. The smart meter model is Eastron SDM120CT-M
(40mA). The CT Model is ESC16-100 (ECHUN)/ CTF16-2K5-100 (Shenke) .The primary
aperture is 10mm, output cable length is 5m . The arrow on the CT must point towards
the inverter. The detailed information about the Meter, please refer to Annex -Eastron
SDM120CT-M (40mA) user manual.(Can also match Chint DSSU666 direct connection
meter)
