Wiring Guidelines
7.1
ESD Protection
Typically, USB devices (keyboard, mouse...) are not equipped with shielded cables. These
devices are disrupted by ESD and in some instances, no longer function.
Before any device is connected to, or disconnected from the terminal, the potential should
be equalized (by touching the control cabinet or ground terminal). Electrostatic loads
(through clothing and shoes) can thereby be dissipated.
7.2
USB Interface Connections
The handheld operating panel has a USB interface. This interface has a USB interface
connection that can be used to connect various USB devices (keyboard, mouse, storage
media, hubs, etc.).
