3.4.7.2 Auxiliary connecting lead terminal, 3-pole (for frame size S3)
Using the 3-pole auxiliary lead terminal, auxiliary and control cables can be
connected to the main cable terminals.

3.4.7.3 EMC module (3RT1916-1P..)
In the case of motors or various inductive loads, back-e.m.f (electromotive
force) is produced at disconnection. This can produce voltage peaks of up to
4000 V with a frequency range of 1 kHz to 10 MHz and a rate of voltage vari-
ation of 0.1 to 20 V/ns.
Capacitive coupling to various analog and digital signals makes suppression
necessary in the load circuit.
Description
The connection of the main conducting path to the EMC suppression mod-
ule reduces the contact sparking that is responsible for contact erosion and
many of the clicks, which in turn supports an EMC-compatible configuration.
