5.4.4 Connection of communication terminal for lithium battery
When using lithium batteries which need to connect BMS system of the battery，
connect lithium battery terminal (RJ45) steps as follows:
5.4.5 Connection of temperature probe for lead-acid battery
When customer using lead-acid battery, the temperature probe of the lead-acid
battery is used to detect the ambient temperature of the lead-acid battery, the
battery temperature cable of the SPH side connection steps are as follows:
1.Thread the swivel nut over the “NTC” cable.
2.Press the cable support sleeve out of the cable gland.
3.Remove the filler plug from the cable support sleeve.
4. Route the “NTC” cable through a min opening in the cable support sleeve.
5. Thread the “NTC” cable through the cable gland.
6. Insert the RJ45 plug of the network cable into the “NTC” pin connector on the
inverter until it snaps into place.
Note：we suggest the distance between battery and SPH no longer than 1.5m, and
The power line area must be larger than 5 AWG.
1.Unscrew the swivel nut from the cable gland for the “RS485” (lithium battery
communication) cable and “NTC” (lead-acid battery temperature sensor) cable and
“DRMs” (only used in Australia) cable and the “CT/Meter” (connection of sensor or
meter communication) cable at the connection cap.
2.Insert LAN cables into RJ45 terminal, the order of the cables as follow, then press
the RJ45 terminal with suitable tools and make sure all of cables are firmly.
3.Connect pressed RJ45 terminal into corresponding port of the inverter.
2. Thread the swivel nut over the “RS485” 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 “RS485” cable through an opening in the cable support sleeve.
6. Thread the “RS485” cable through the cable gland.
7. Insert the RJ45 plug of the network cable into the “RS485” pin connector on the
inverter until it snaps into place.

Note：If you are using a lead-acid battery, you do not need to install this
communication cable,please skip this step to 5.3.5.
