ODU
● L1 + L2 + Ln + Lt ≤ 1,200 m, communication wire 3 × 0.75 mm².
● After the last IDU, the communication wire should not route back the ODU to form a closed loop.
● Connect a 120ohm resistor between terminals P and Q of the last IDU.
● All communication wires between IDU and ODU must be in serial connection. Shielded cables shall be used. Connect
the shielding nets at both ends of the shielded cable to the sheet metal " " of the electrical control box.
● Applicable standards: EN 55014-1 and EN 55014-2.
