Push-in Technology and Wiring
The push-in spring clamp mechanism secures wires without screws or tools. You simply insert a stripped wire into the terminal opening firmly. The ABB 1SAP210600R0001 releases the wire by pressing a small orange push-button. A standard 2.5 mm screwdriver activates the release mechanism for each terminal. The spring maintains constant pressure on the wire for reliable contact. Consequently, vibration will not loosen the connection over time. Each terminal accepts solid or stranded copper wire exclusively. You can also use ferruled wires with this terminal type.
Module Compatibility and Mounting
This interface unit connects directly to ABB AC500 I/O modules with 20-pin interfaces. The unit locks onto the module with an integrated latching mechanism. The ABB 1SAP210600R0001 includes mechanical coding to prevent incorrect installation. You can attach the included labeling strip for wire identification purposes. The unit carries pre-printed terminal numbers for easy reference. You can remove the unit without disturbing any field wiring. The unit fits both standard and high-density I/O module types.
Installation and Wiring Guidelines
You must mount the interface unit onto the I/O module before DIN rail installation. The coding pins must match the corresponding sockets on the module. You should strip exactly 8 to 10 mm of insulation from each wire end. Longer strips risk short circuits between adjacent terminals. The ABB 1SAP210600R0001 requires no maintenance after installation. You should label each wire according to your electrical schematic drawings. The unit does not require any power or configuration for operation. You should verify each wire inserts fully into the terminal opening.
