① Run the network cable through the electric conduit, remove the insulation jacket from both ends. The color of
network cable should comply with the local regulations.
② Fan out the wires in the order of 568B (white/orange, solid orange, white/green, solid blue, white/blue, solid
green, white/brown, solid brown).
③ Insert the wires into the connector.
④ Crimp the connector using a crimping tool.
⑤ The cable is ready.

RJ-45 Connector:
Both network cable connection and 20V power supply must be used in conjunction when the communication cable length between aPower and aGate is longer than 100ft. The network cable
should form a loop between aPower and aGate similar to installations with distances less than 100ft. Insert the network cable between aGate and aPower 1 into the “CAN OUT” port of
aGate and the “CAN IN” port of aPower 1; insert the network cable between aPower 1 and aPower 2 into the “CAN OUT” port of aPower 1 and the “CAN IN” port of aPower 2; insert the
network cable between aPower 2 and aPower3 into the “CAN OUT” port of aPower 2 and the “CAN IN” port of aPower 3, so on and so forth until the connection between aPower N and
aGate, where the network cable should be inserted into the “CAN OUT” port of aPower N and the “CAN IN” port of aGate. The 20V power supply should be wired in series.
