Hardware Installation
Note: you need to get a R-core transformer yourself
Or you can buy one online, please refer to: X10-RTR Power Supply Unit

IMPORTANT !!!(Read Me)
Connect the R-core transformer to the X10-PWR board

  1. Make sure all ports on terminal block are open (Turn clockwise to tighten, counter-clockwise to loosen). 
  2. Insert wires into the terminal block in the correct order.
  3. Tighten down the screws the wires you have inserted. Try pulling each wire out of terminal block in order to insure that they are fastened securely.

IMPORTANT !!!
AC voltage Selector
110V : AC input voltage MUST be 110~120VAC
220V : AC input voltage MUST be 220~230VAC

a) Make sure that you know what voltage is being supplied by the power outlet before setting the voltage selector switch and before connecting the power cord.
b) To switch the selection, unplug the power cord and use a small screwdriver to slide the switch to the opposite position.
