Step 2: Insert the exposed core wires into the OT terminal and crimp them
by using a crimping tool, as shown as Figure 4-3.

L3 is the length between the insulation layer of the ground cable and crimped
part. L4 is the distance between the crimped part and core wires protruding
from the crimped part.
Step 3: Tighten the OT terminal by using M6 screw. Recommend torque is
5N.m
Note:
• Please select the correct size lug for the earth wire.
• Good grounding for the SOFAR 3.3K~12KTL-X can help resist the impact
of the surge voltage and improve the EMI performance. First connect the
ground cable before connecting the AC power cable, DC power cable, and
communication cable.
• For the system with one SOFAR 3.3K~12KTL-X, connect the ground cable
to the ground. For the system with multiple SOFAR 3.3K~12KTL-X, connect
the ground cables of all SOFAR 3.3K~12KTL-X to the grounding electrode
using equipotential bonding.
• If the installation location is near the ground, first connect the ground cable
to the ground before installing the SOFAR 3.3K~12KTL-X on the wall.
