10.2 Shielding
For Ethernet, CAT5e-compliant
cables
are recommended. The cable shielding is connected
to ground via the RJ45 connector. Noise signals can then be prevented from reaching the
electronics and affecting the function.
10.3 ESD Protection
Typically, USB devices (keyboard, mouse etc.) are not equipped with
shielded cables. These devices are disrupted by electrostatic discharge and
in some instances, no longer function.
Before any device is connected to- or disconnected from the product, the
potential with ground must be equalized (by touching the control cabinet or
ground terminal). Electrostatic loads (through clothing or shoes) can be
thereby dissipated.
10.4 USB Interface Connections
The product has a USB interface. This interface can be used to connect various USB devices
(keyboard, mouse, storage media, hubs, etc.). Several USB devices can be connected using
a hub, which are then fully functional.
