self-power the hub; the
voltage can be in the range
from +7V to 48VDC.

1.3 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 48V) to the 2-pin Terminal Block
Connector. The hub is bus-powered by the upstream USB port (USB-B
connector), The terminal block connector is to add power to ensure enough
power for the 4 downstream ports.
3. Connecting USB Host cables: The host cable could be either a standard B-to-
A USB 3.1 cable. Please connect the Type-A end connector of the cable to
your PC’s host USB 3.1 port, then connect the type-B end connector to the
hub. Since the USB hub is plug-and-play, you don’t have to turn off your host
computer when installing the hub.
4. Connect the USB Devices to the downstream ports of this hub.
5. Mount your hub on the wall or DIN RAIL if required.
