Professional FAQ

• What types of wire ferrules work with this connector?
• The connector accepts DIN 46228 Type A ferrules without plastic collar (5-7mm) or Type E with plastic collar (up to 6mm). Always use quality ferrules for reliable connections.
• Can I mix different wire sizes in the same connector?
• You can combine two conductors up to 1.5mm² total in one terminal. Ensure both wires fit properly and the screw clamps them securely without damage.
• How do I properly remove the connector from the module?
• Use a standard flat-head tool to release the locking mechanism. Insert the tool into the designated slot and gently lever the connector away from the module.
• What is the maximum wire length I can use with this connector?
• While the connector itself doesn't limit wire length, follow Siemens guidelines for signal integrity. Typically, keep analog signals under 100 meters and digital under 1000 meters.
• Does this connector support both input and output signals?
• Yes, the connector works with both input and output signal modules. The wiring depends on the specific S7-300 module you connect to the front interface.
