Installation Guidelines

Ensure the PLC system is powered down before inserting or removing the front connector from any module.
Strip wires to exactly 6 mm to ensure proper seating within the terminal block.
Use a conical screwdriver with a 3 to 3.5 mm blade width for terminal screw adjustment.
Tighten screws to the specified 0.4 to 0.7 Nm torque range; do not overtighten to avoid damaging plastic threads.
Utilize the integrated plastic strap for strain relief to prevent mechanical stress on the terminal connections.
Verify the mechanical coding elements are correctly aligned before plugging the connector into the module.

FAQ

Does this connector have a coding mechanism to prevent inserting it into the wrong module?

Yes, it includes mechanical coding elements that physically prevent the connector from being plugged into an incompatible module type, ensuring safety during maintenance.

Can I replace a faulty S7-300 module without rewiring?

Yes, the front connector is designed to be unclipped from the faulty module and reconnected to the replacement unit, significantly reducing downtime and potential wiring errors.

What wire types are supported?

The terminals accept solid and flexible conductors from 0.25 mm² to 1.5 mm², with or without end sleeves. It supports one conductor per terminal or two conductors in a shared ferrule up to 1.5 mm² total.
