RJ45 terminal pin assignment
Method of asserting demand response modes
Note:
If the cable such as “NTC” (lead-acid battery temperature sensor) cable is not used,
please do not remove the filler plug from the cable support sleeve.
5.4.8 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:
Step1: Unscrew the swivel nut from the cable gland.
Step2: Thread the swivel nut over the “NTC” cable.
Step3: Press the cable support sleeve out of the cable gland.
Step4: Remove the filler plug from the cable support sleeve.
Step5: Route the “NTC” cable through a min opening in the cable support sleeve.
Step6: Thread the “NTC” cable through the cable gland.
Step7: Insert the RJ45 plug of the network cable into the “NTC” pin connector on the
inverter until it snaps into place.
Step8: If no other cables need to be installed, lock the waterproof cover to the inverter
with screws.
Step9: Screw the swivel nut onto the waterproof cover.

Note:
1. If you are using a lithium battery, you do not need to install this temperature probe,
the probe of the temperature cable should be attached to the surrounding environment
of the lead-acid battery, and the length of this cable is 1.5m, so pay attention to the
distance of battery and SPH.
2.If the cable such as “NTC” (lead-acid battery temperature sensor) cable is not used,
please do not remove the filler plug from the cable support sleeve.
