5.6 Wiring rules for spring-loaded terminals (with push-in technology)
Notes on handling spring-loaded terminals with push-in technology
The terminal area of the spring-loaded terminals is rectangular, and the maximum overall
dimensions of the conductor to be wired must not exceed 2.4 x 2.8 mm.
Attention must be paid to the orientation of the terminal area, which may call for vertical
fitting of rectangularly crimped cables.
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 generally
very highly suitable in this case.
When use is made of a cable that utilizes the full overall height, the terminal's spring is
deflected to the maximum. Therefore, removal of this cable may become a problem because
it requires further deflection of the spring.
