➭ Switch off auxiliary voltage.

➭ Remove the front plate.

➭ Connect the customer wiring ⑦ to the terminal strip ⑥ or directly to the equipment

terminals (e.g. CAPDIS S2+, short-circuit indicators) according to the circuit diagrams, and

lay it cleanly.

➭ If available, use the wiring duct ① on the operating mechanism box and the lateral wiring

ducts ② .

- Lead the secondary wires of the current transformers and voltage transformers through

steel mesh tubes or steel tubes in a shielded way into a lateral wiring duct.

- Earth the steel mesh tubes or steel tubes with metal cable straps.

➭ Avoid extra-long secondary wires or lay them in the wiring ducts ① and ② or the fixing

duct ⑤ in a meandering pattern.
