Plug Load Controller (PLC) (PC-01-20)

Download the Plug Load Controller Installation Guide.


  • Install the Plug Load Controller (PLC) in the Main Junction Box (J-box) of the outlet(s) or load they control, and the PLC must be properly wired to the receptacle(s) or loads.
  • For Open Office receptacle control, the PLC must be installed within the wireless range of the gateway, as well as any sensor of the Motion group that they belong to.
  • PLCs need to hear from only one sensor of the Motion group and do not need to hear from all sensors of the group.
  • The controlling sensor should belong to the same Motion group to which the PLC Gateway is assigned. Make sure the controlling sensor is placed near the electrical closet if that closet is where the PLC is installed.
  • The PLC must not be installed under a raised floor for floor outlets, as that floor may interfere with wireless communication.
  • For Circuit level control, install the PLC in the electrical room, near the electrical panel for easy access, and provide a Gateway in the room for wireless connectivity.
  • PLCs are shipped with two labels with the MAC address printed. After the electrician installs the PLC, affix one label to the outlet faceplate and the other label in the blueprint floorplan marking the PLC location.


The Enlighted Plug Load Controller (PLC) transforms receptacles in 20A circuits to controlled and metered smart receptacles for energy-efficient and code-compliant plug load control. The device is paired with a sensor or a group of sensors in the network to enable occupancy-based control. The controller features two sets of wires to power separately controlled and uncontrolled outlets to measure energy consumption on both uncontrolled and controlled circuits separately.

Shipped Components

  • Plug load controller (and ½ inch locknut)
  • MAC address sticker

Tools You May Need

  • Wire stripper

Supplies You May Need

  • Wire nuts (or connectors)
  • Junction box (j-box)
  • Two Conductor plus ground 12 AWG solid wire cable
  • Three Conductor plus ground 12 AWG solid wire cable
  • Clamps


A qualified electrician must perform installation and maintenance following local, state, and national electrical codes (NEC) and requirements.

Junction Box Installation

Step 1: Punch out a ½ inch knock out in the J-box and insert the threaded end of the Plug Load Controller (PLC). Secure the PLC to the J-box with the provided locknut (See Figure 2).

Step 2: The Mains Wiring to the J-box shall be appropriately sized for the circuit with Hot, Neutral, and Ground wiring present (See Figure 3).

Step 3: In the J-box, connect the PLC’s four12 AWG conductor leads to the Mains wiring and the receptacle wires that run from the J-box to the receptacle wall box (See Figure 4).

Step 4: Using wire nuts (or wire connectors):

  1. Connect the hot wire from the main feed to the black wire of the plug load controller (PLC).
  2. Connect the neutral wire from the main feed to the white wire of the PLC and the neutral wire that feeds through to the receptacle.
  3. Connect the red wire of the PLC to the switched hot wire that feeds through to the receptacle.
  4. Connect the blue wire of the PLC to the hot wire that feeds through to the receptacle.
  5. Connect all ground wires to the Grounding stud on the J-box.

Receptacle Installation

Step 5: Break the connection on the “hot side” of the receptacle between the two outlets (see Figure 4).

Step 6: Connect the neutral wire to the neutral connection on the receptacle.

Step 7: Connect the switched hot wire to the hot side of the “controlled outlet”.

Step 8: Connect the hot wire to the hot connection of the “uncontrolled outlet” (always powered).

Step 9: Install the receptacle in the wall box.

Step 10: Attach a receptacle faceplate that distinguishes the controlled outlet.

Step 11: Attach the included MAC address sticker on the faceplate and the other label in the floorplan blueprint marking the location of the PLC.

Problem Solution
LED is not on when the device is powered

1. Check to see that power is present from the circuit panel.

2. Check the wiring, if LED does not come on, then replace the device.

LED Description

LED Status


LED not on

No Power, check power connection

Slow Blinking Green

Normal PLC Commissioned.

Continuous Blinking Green

Immediately boot and uncommission.

Slow Blinking Red

Check for wiring errors.

Continuous Blinking  Red

Commissioning error, RMA and delete the PLC from Manage, rediscover PLC and commission or replace unit.

Red and Green continuous blinking

Booting time should be less than 5 seconds.

Note: If both green and red LEDs stay on continuously for more than 10 seconds, replace the unit.
