Intended Use
The USB Isolator 2 kV HS manufactured by Wiesemann & Theis
galvanically isolates Low-, Full- and High-speed USB connections
with an isolation voltage of at least 2,000 V. The isolator prevents
compensating currents from flowing over the USB line due to
potential differences between the connected devices. This way
the risk of data transmission disturbances or destruction of the
interfaces can be reduced. For this purpose the isolator can simply
be inserted into the existing USB connection.

DANGER
The isolator described in this manual may only be used to protect
the USB interfaces. It is not permitted to use the isolator to protect
personnel against contact with dangerous voltages. If a safety-
critical electrical isolation is required, please contact us.
Any other use or modification of the equipment is not authorized.
Electrical safety
Please make sure there is sufficient distance between upstream
and downstream cable to avoid direct voltage flashovers between
the cables.
The USB-Isolator may only be used in enclosed and dry areas.
The device should not be exposed to high ambient temperatures
and should not be operated near heat sources. Please note the
restrictions regarding the maximum ambient temperature.
The power supply unit used to supply the respective USB-Isolator
must guarantee a safe separation of the low voltage side from the
grid in accordance with EN62368-1 and have „LPS“ characteristics.
