14.2 Installation and Connection
190 Digital Fault Recorder, SIMEAS R-PMU, Manual
E50417-H1076-C360-A5, Release 10.2012
14.2.2 Connecting Cables
The cables with analog signals (current, voltage), with the binary signals (signal inputs), the
control signals and the power supply are always connected from the back to the rear panel.
Cable shield
For all cables connected to SIMEAS R-PMU, you have to use copper shielded cables.
The cables are fastened to the shield contact using clamps. To ensure interference immunity,
the cable insulation must be removed in the clamp area. This provides a reliable connection
between the shield and the shield contact. The cables leading to a printer, modem or PC are also
connected to the rear panel. The connection of external devices within a cabinet that meets EMC
requirements does not necessarily require earthing.
Note
The protection against interference emission, however, is significantly increased when the cable
shield is connected to the shield contact.
