Ground cable: outdoor copper-core cables with a cross sectional area of 4–6 mm

12–10 AWG are recommended.

OT terminal: M6

The length of removed insulation layer (L2) must be 2–3 mm longer than the cable crimping length of

the OT terminal (L1).

The cavity formed after the conductor crimp strip is crimped must wrap the core wires completely. The

core wires must contact the terminal closely.
