6.6.3 Grounding Protection (PE)
Step 1: It is recommended to use a 12AWG outdoor power cable and RNB3.5-5S OT
terminals. Strip the insulation layer of the ground cable with a cable stripper to a
proper length. See Fig. 6-9-1.
Step 2: Insert the exposed core wires into the OT terminal and crimp them with a
crimper, as shown in Fig. 6-9-2.
Step 3: Fix the OT terminal with M5 screws at the position shown in Fig. 6-9-3.
Recommended torque: 3N m (27 to 32 in-lbs).
Note: L3 is the length between the insulation of the cable and the crimped part. L4
is the length between the crimped part and core wires protruding from the
crimped part.
Danger
The positive and negative terminals of the PV (photovoltaic) system
inverter should not be grounded, as it may lead to inverter failure.
However, it is important to ground all non-current carrying metal parts,
including brackets, distribution boxes, inverter enclosures, battery pack
enclosures, and other relevant components.
