8.2.9 Connecting spring-loaded (push-in) terminals
WARNING
Hazardous Voltage
Can Cause Death, Serious Injury, or Property Damage.
Before starting work, therefore, disconnect the system and devices from the power supply.
The spring-loaded (push-in) system allows wiring without tools for rigid conductors or
conductors equipped with end sleeves.
A screwdriver is required for wiring nely-stranded or stranded conductors without end sleeves
on spring-loaded (push-in) terminals.
Tools and materials
• 0.5 x 3 mm screwdriver DIN 5264 (for nely-stranded conductors only).
• For suitable connection cross-sections of the cables, see the chapter "Connection data for
3SK1 terminals (Page 157)".
