USB / COM X3
Connector type:
USB B
The USB port
COM
is electrically isolated from GND to prevent ground loops (functional isolation).
When the USB cable is plugged in or unplugged during operation, or when the virtual COM port is
initialized by the operating system (for example, when being assigned to another application), a reset
is initiated and the device changes to the shutdown state. If this is disruptive, the reset signal coming
from the COM port can be interrupted via a DIP switch (S3-6). In this configuration, however, no
software download (internal program update) is possible.

The high voltage connector may only be mated or unmated when the supply voltage is switched off!
Otherwise, there is a risk of electric shock.

Earthing
The M4 earth bolt on the back panel of the device must be connected to the central earthing point of
the test set-up and to protective earth.
