Connection of Dry Contact
The dry contact is used to communicate with external devices (such as remote start hot
water heater). The wiring steps are as follows:
1.Unscrew the swivel nut from the cable gland.
2.Thread the swivel nut over the 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 network cable through an opening in the cable support sleeve.
6.Thread the network cable through the cable gland.
7.Thread cables into connection terminal of the inverter, then press the terminal by
relevant tools and make sure cables are firmly.
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:
If the cable such as “Dry contact” cable is not used, please do not remove the filler plug
from the cable support sleeve.
5.4.12
Grounding Connection
JKS must be grounded by cable, the grounding point is showed as follow, and the
2
minimum grounding cable wire diameter is 10.0mm .
PV Array Grounding
Grounding conductor of PV panel brackets must be firmly connected to earth at PV array
side and inverter side and SP side. The sectional area of grounding conductor should be
equal to the sectional area of DC grounding conductor. The minimum wire diameter is
2
10.0mm .
DC Grounding
Select the DC Grounding mode according to the local standard and use the PV grounding
terminal box and DC Grounding wires of the same specification.
Grounding Device
If the positive pole or the negative pole of PV array needs to be grounded in the PV
system, the inverter output should be insulated by Isolation Transformer. Isolation
transformer must conform to IEC62109-1,-2 standard.
Connection as below:
1.JKS-3~6HLVS-ABI series inverters are all single-phase inverters, If the
inverter is installed in Australia or New Zealand the inverter must not
be used as part of a three-phase combination
2. This inverter complies with IEC 62109-2 clause 13.9 for earth fault
alarm monitoring.
If an Earth Fault Alarm occurs,the fault code "Error303,NE abnormal"
will be displayed on the inverter screen while the LED indicator red will
light up.(Applicable to inverters with graphical display only)
