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 1.5 x 2.4 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.
