Series 8118/1, Series 8118/2
6.2.1 Conductor Connection
Select suitable conductors that do not exceed the permitted heating temperature within the
enclosure.
Ensure that conductors have the specified cross-sections.
Guide the conductor insulation to the terminals
(for the stripping length, see "Technical data").
Do not damage the conductor when stripping the insulation (e.g. by denting it).
Fit the core end sleeves properly using a suitable tool.
If the system is equipped with all possible terminals and live conductors, and the maximum
current load has been reached, ensure that the length of a conductor from the screw
connection to the clamping unit does not exceed the diagonal planes of the enclosure.
