JUST POWER ON86
3.4 Connection ground protection（PE）
Prerequisite: Prepare the ground cable 2.5mm2 ～ 4mm2 yellow green outdoor
power cable and Rnb3.5-5s round bare terminal are recommended
Step 1 : Strip the insulation layer of the ground cable with a wire stripper to a
proper length as shown in Figure. 6-3-1.
Step 2 : Thread the stripped insulation core into the conductor crimping area of OT
terminal and press it tightly with crimping pliers as shown in the figure 6-3-2。
Step 3 : Fix the to terminal with M5 screws at the position shown in figure 6-3-3.
The locking torque is recommended to be 3nm.
Note 1 : L3 is the distance between the insulated terminal surface of the cable
and the rear section of the terminal conductor crimping area, and L4 is the
length of the conductor of the cable protruding from the terminal conductor
crimping area.
Note 2 : The cavity formed after the crimping of the conductor crimping piece of
the terminal should completely cover the cable conductor, and the cable
conductor and the terminal should be closely combined.
Danger
The PV positive pole and negative pole of the inverter cannot be
grounded, otherwise the inverter will fail.
In EP600 energy storage system, all non-current carrying metal
parts (such as bracket, distribution box, inverter shell, battery pack
shell, etc.) should connect to the ground.
L2 is 3mm longer than L1
3-3-1
L2=L1+3mm
