Wiring rules for spring-loaded terminals (with push-in technology)
Notes on handling spring-loaded terminals with push-in technology
The space for the spring-loaded terminals is rectangular. The maximum overall dimensions
of the conductor to be wired must not exceed 2.4 x 2.8 mm.
Take note of the orientation of the terminal area, which may require vertical fitting of
rectangular-crimped conductors.
To make optimum use of available terminal area, you are advised to choose a form of
crimping that creates a corresponding rectangular contour. Trapezoidal crimping is highly
suitable in this case.
When a conductor is used that utilizes the full overall height, the terminal spring is deflected
to the maximum. It may therefore be difficult to remove this conductor because it requires
further deflection of the spring.
