Each DC powered switch comes with a set containing a prewired, 3-inch 8 AWG, power supply connector and a four-screw wiring block. One set is provided for each DC PSU.

Strip a 1/2-inch section of insulation from each of the power connector wires, as shown.
Insert each of the power connector’s bare wire lengths into the wiring block. The blue wire is
-48V, the black wire is the positive return, and the yellow/green wire is the ground wire, as shown.
Use a flat-head screwdriver to tighten the screws that secures the bare wires into the wiring block.
Secure the site’s DC power source wires to the other side of the wiring block, see steps 1 and 3.
NOTE:Do not cross the wires.
Insert the DC power connector into the power socket of the DC PSU. Ensure that the connector pins firmly seat and you hear the click of the power connector’s left and right levered clamps lock into place.
NOTE:Never try to force the power connector into or out of the DC PSU power socket.
NOTE:To remove the power connector from a DC PSU, squeeze the levers on both sides of the connector. Doing so disengages the power connector’s clamps. While continuing to squeeze, pull the power connector from the DC PSU socket.
