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
521 processor module over a large surface (cable grommets, grounding clamps)!
Noise signals can therefore be prohibited from reaching the electronics and affecting the
function.
ESD Protection
Before any device is connected to or disconnected from the CCP 521, the potential with
ground should be equalized (by touching the control cabinet or earth terminal). Static elec-
tricity (from clothing, footwear) can therefore be reduced.
Working with and on the CCP 521
Valid operating and safety guidelines for personal safety must always be observed.
With installation /initial start-up / product maintenance, the relevant measures for ESD
protection must be taken.
(For example: the employees must ground themselves before they start working with and on the
product.
