4-Port USB2.0 Metal Hub with DIN RAIL Mounting Kit
 Activity LEDs for Downstream Ports: These 4 LED indicators
are blinking whenever the USB ports are transferring data.
 Upstream Port Connector: Type-B connector from upstream
USB2.0 port. It is connected from host or another USB2.0
hub.
 Self Power Input Connectors: This 3-pin (one pin plus voltage
and the other 2 pins are GND) terminal block connectors
are used to connect strong power to self-power the hub,
the voltage can be in the range from +7V to 24VDC.
Warning!!
Please make sure the polarity of the input power should be
correctly match the terminal block pins, otherwise it will
damage the hub.

3. Hardware Installation
1. Use static electricity discharge precautions.
Remove possible static discharge potential from any
objects that the hub may come in contact with before
installation. This can be accomplished by touching a bare
metal chassis rail after you have turned off the power.
2. Apply DC power (range from +7V to 24V) to the 3-pin
Terminal Block Connector. The hub was bus-powered by
the upstream USB port, this terminal block connector is to
add power to ensure enough power for the 4 downstream
ports.
