7-Port USB2.0 Metal Hub with DIN RAIL Mounting Kit
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 2-pin (one pin plus voltage and the other pin is 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 2-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 7 downstream ports.
3.Connecting USB Host cable: The host cable is either a standard A-to-B USB2.0 cable or a screw-lock type A-to-B cable. Please connect the type-A end connector of the cable to your upstream USB port, then connect the type-B
