• Connection of one cable per opening.
• Rigid and flexible cables with end sleeves may be directly
connected.
• If flexible cables without end sleeves are to be connected,
the terminal
must be opened. Splicing of the wires must be avoided.
• The cable must be inserted into the terminal either as far
as possible
or in such a way that a sufficient connection is obvious.
• The tightness of the connection must be checked.
Disconnection of cables
The cables may only be removed after operating the terminal’s opening mchanism.
• If one cable is removed, the correct position of the remaining cable must be checked.
Processing instructions
The screwless terminal at the load side of the S 200 S
is designed so that copper cables basically may be
connected without further preparation. If end sleeves are
used as splicing protection for flexible cables, the
compression
of the end sleeves must comply with the pull-out forces in
accordance with standard IEC/EN 60898-1 table J.3.
Recommended tools for flexible cables with end sleeves
Crimp tool with trapezoid compression profile
Wire stripping length / size of end sleeves for all cables
Wire stripping length and end sleeve length 12 (+2) mm
Distribution boards with metal cover
The distance from a metallic cover to the “shoulder”
of the miniature circuit breaker must be at least 6 mm
on the load side due to the arrangement of the easiliy
accessible measurement point.
