Safety Regulations
INU servers are network devices for use in industrial
environments. The INU-100 is designed for the integration of
USB devices into TCP/IP networks.
• Read the documentation and make sure that your system
meets the requirements listed therein.
• The device must only be connected to the mains and to
the network by qualified personnel.
• Avoid contact with humidity or liquids.
• The device must only be connected and operated if it is in
perfect condition.
• Do not connect a telephone cable to the RJ-45 connector.
The RJ-45 connector may only be connected to SELV volt-
ages. For the connection to the RJ-45 connector only STP
cabling (category 5 or better) may be used. The shielding
must fit flushly to the connector.
• Do not open the housing. Unauthorized modifications to
the device can affect the product certification and are for-
bidden.
• Only use a certified USB cable (< 3 m) listed at
www.usb.org.
• The device and the power supply or power supplies must

be installed in the same control cabinet.
• The low-voltage cable between the power supply and the
device must not be longer than 3 m.
• The maximum load for the relay contacts is 60 V for DC /
42 V for AC and a current of max. 3 A.
• Choose cables with a suitable wire cross-section for the
connection to power supply and relay.
