Installing and Removing the Controller

Follow these steps to install the controller in an NF panelboard.

Controllers on Standard and Column-width Panelboards

1. Turn off all power supplying this device and the equipment in which it is installed. Verify that the power is off using a properly rated voltage sensing device.

2. Remove the panelboard cover and deadfront.

3. Insert the controller’s two bus connectors into the vertical bus connections on the right control bus. See Controllers on Standard and Column-width Panelboards.

   NOTE: If using a standard NF panelboard, the controller is installed at the top of the right control bus. If using a column-width NF panelboard, the controller is installed at the top of the panelboard. See Controllers on Standard and Column-width Panelboards.

4. Push the controller onto the control bus until the mounting feet snap onto the panelboard interior. A captive screw on the left side of the controller is lined up with a hole on the panelboard interior. Use a screwdriver to secure the screw. Torque to 20–30 lb-in.

   NOTE: Install the power supply according to its instruction bulletin, if not already installed.

5. Push the power supply connector plug into the power connection on the controller. See Components of the Controller.

   NOTE: If using a column-width NF panelboard, the column-width controller cable NFCWG3 is required to connect the power supply and controller.

To remove the controller, follow these steps:

1. Turn off all power supplying this device and the equipment it is installed. Verify that power is off using a properly rated voltage sensing device.

2. Remove the panelboard cover and deadfront.

3. Unplug the controller’s power supply connector from the power supply.

4. Loosen the controller’s captive screw from the panelboard interior.

5. Grasping the controller by the edges, lift straight out until the controller disengages.

   NOTE: Powerlink control buses include a mode where all Powerlink circuit breakers are turned ON approximately 10 minutes after communication is lost with a controller as long as the control buses are still receiving power.
