16.4.2 FORTiS-N FS grounding and shielding
– Siemens DRIVE-CLiQ versions
Encoder
Readhead cable
NOTE: On Siemens DRIVE-CLiQ systems the connector between the readhead cable and
extension cable will mate via the A-9796-0575 interface.
IMPORTANT:
1.
The shield should be connected to the machine Earth (Field Ground).
2.
If the flying lead variant is used or the connector is modified or replaced, the customer must
ensure that both 0 V cores (white and green) are connected to 0 V. In such situations, care
should also be taken to ensure that 0 V and Earth remain properly insulated from each other
throughout the cable run.
3.
If the original termination supplied with the FORTiS-N FS encoder system is altered or a
non-Renishaw cable that is not approved is used, then it is the responsibility of the system
manufacturer to make sure the system is compliant with IEC 61800‑5‑2:2016 Electromagnetic
immunity requirement for safety related systems – Annex E, second environment.
