11.2 Shielding
The wiring for the CAN bus, Ethernet and VARAN bus must be shielded. The low-ohm
shielding is either connected at the entry to the control cabinet or directly before the
CCP 621 processor module over a large surface (cable grommets, grounding clamps)!
Noise signals can therefore be prevented from reaching the electronics and affecting the
function.
11.3 ESD Protection
Before any device is connected to or disconnected from the CCP 621, the potential with
ground must be equalized (by touching the control cabinet or earth terminal). This will allow
the dissipation of electrostatic loads (caused by clothing/shoes).
