- Core Functions and Features
- Screwless Wiring Technology: Adopts push-in terminals, enabling tool-free wiring. Reduces wiring time by more than 50% and avoids poor contact caused by over-tightened or under-tightened screws.
- Dual Wire Entry: Each terminal can independently accommodate 2 wires, facilitating bridging and branch connections, and simplifying the wiring of complex circuits.
- Safe Terminal Layout: Coil terminals and contact terminals are completely separated, preventing wrong wiring and improving operational safety.
- Easy Relay Replacement: Equipped with a dedicated ejector, the relay can be easily removed with the separation lever (P2CM-S, sold separately) without disconnecting the wiring.
- Dual Mounting Options: Supports standard 35mm DIN rail clipping and screw fixing, suitable for different installation scenarios.
- Finger Protection Design: Terminals are equipped with protective structures to prevent electric shock hazards, meeting the IP20 protection requirements.
- Nameplate Compatibility: Can be installed with R99-11 series nameplates (sold separately) for convenient circuit identification and maintenance.

- Installations- und Verkabelungshandbuch
Installationsschritte
- DIN-Schienenmontage:
– Clip the socket onto a 35mm standard DIN rail and ensure the claws are fully engaged.
– Insert a screwdriver into the fixing slot and push in the direction of the arrow to confirm secure installation.
- Surface Mounting:
– Fix it on the mounting panel with M3 screws; the mounting hole spacing conforms to standard dimensions.
– Ensure the mounting surface is flat to avoid socket deformation that may affect wiring.
Wiring Process (Completed in Three Steps)
- Insert a screwdriver (φ3.0mm) into the operation hole on the side of the terminal.
- Strip 8~9mm of insulation from the wire and insert the wire into the terminal hole.
- Pull out the screwdriver; the push-in spring automatically clamps the wire to complete the connection.
Relay Installation and Removal
- Installation: Align the G2R-2-S relay with the socket pins and press vertically downwards until it is fully engaged.
- Removal:
– Install the P2CM-S separation lever (sold separately) on both sides of the socket.
– Insert a screwdriver into the separation lever hole and gently pry upwards to eject the relay.
