Installing the Control Bus

Follow these instructions to install the control bus into a panelboard. The installation is illustrated in Figure 3. If installing the control bus into a column-width panelboard, refer to Column-width Control Bus Installation.

DANGER
hazard of electric shock, explosion, or arc flash Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E, NOM-029-STPS or CSA Z462 or local equivalent. Electrical equipment must be installed, operated, serviced, and maintained only by qualified personnel. Turn off all power supplying the panelboard interior and the equipment in which it is installed before working on or inside equipment. Always use a properly rated voltage sensing device to confirm power is off. Replace all devices, doors, and covers before turning on power to this equipment. Before energizing panelboard, all unused spaces must be filled with blank fillers. Failure to follow these instructions will result in death or serious injury.

Remove the panelboard cover and deadfront. Verify that all power is off using a properly rated voltage sensing device.
Remove all branch circuit breakers (not required).
Position the left control bus so its mounting feet are aligned with the holes on the left interior rail in the panelboard. Notice that the vertical bus connections for the power supply are at the top of the control bus (see Figure 3).

Control Bus Installation
Secure the mounting feet to the interior rail using the screws provided and a screwdriver. Torque the screw 20 to 30 lb-in.(2.3 to 3.4 N•m), then verify that the control bus is securely mounted to the interior rail and does not move or slide on the rail.
If a right control bus is needed, position it so the mounting feet are aligned with the holes on the right interior rail in the panelboard. Notice that the vertical bus connections for the controller are at the top of the control bus.
Secure the mounting feet to the interior rail using the screws provided and a screwdriver. Verify that the control bus is securely mounted to the interior rail and does not move or slide on the rail.
Proceed with the installation of Powerlink remote-controlled circuit breakers, controller, or power supply as indicated in related installation information. If finished with the installation, replace the deadfront and panelboard cover, and turn on the power.
