Shielding - Siemens SICAM TM Installation Manual

Shielding / Protective Earthing
10.1.

Shielding

Basically the TM-modules are designed in such a way that no shielded cables are required.
Normally, shielded cables are strain-relieved directly after the cabinet/rack entry and then
grounded on a large-surface screening rail installed for this purpose. The terminal modules
themselves provide no possibility of shield clamping.
Exception
For the module TE-6450 used for position acquisition, the screened cable must be conducted interruption-
free from the shaft encoder directly up to the module. There the screening is carried out with special
clamps (screen clamp plate). (For details refer to section 9.3,
90
"TE-6450 – Wiring the Data Transmission").
