???? Wiring Diagram (Basic NC Connection)
[Power Supply] ---> [E-Stop NC] ---> [Contactor Coil] ---> [Ground]
When pressed, the NC contact opens, cutting power to the contactor coil and stopping the machine.
Dual-channel wiring (2NC contacts in series) is recommended for safety redundancy (PL e/Cat. 4).
⚠️ Installation Notes
Mounting:
Install in visible, accessible locations near operator stations.
Use M20 or 22mm mounting hole (standard for mushroom heads).
Wiring:
Use shielded cables in high-noise environments.
Test regularly to ensure immediate shutdown.
Safety:
Pair with safety relays (e.g., Siemens 3SK1) for SIL 3/PL e compliance.
????️ Accessories
Extension buttons (for multi-location e-stop).
Protective covers (to prevent accidental presses).
Labeling plates (e.g., "EMERGENCY STOP" in multiple languages).
