5.5.9 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.Unscrew the swivel nut from the cable gland.
2.Thread the swivel nut over the “NTC” 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 “NTC” cable through a min opening in the cable support sleeve.
6.Thread the “NTC” cable through the cable gland.
7.Insert the RJ45 plug of the network cable into the “NTC” 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.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.
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.
