Installing the Secondary Address Selector

1. Turn of all power to the panelboard.

2. Remove the panelboard cover and deadfront, then confirm that all power is off using a properly rated voltage sensing device.

   NOTE: The subnet must not extend farther than 400 feet (122 m) from the primary panel, unless a powered secondary panel is used.

3. Using the four-wire 18 AWG subnet cable (General Cable 236100, Belden 27326, or equivalent), insert one of the four colored wires into terminal B of a subnet connector plug (see Subnet Connector Wire Installation).

   NOTE: Schneider Electric subnet cables NFSN06 (six-foot [1.8 m]), NFSN25 (twenty-five foot [7.6 m]), or NFSN50 (fifty-foot [15.2 m]).

4. If connecting to another secondary panelboard, insert the same colored wire from the next four-wire 18 AWG subnet cable into terminal B (see Subnet Connector Wire Installation).

   NOTE: If there are multiple secondary panels, it is important to use the same wire color sequence for each additional subnet connector. For example, if blue wire is inserted into terminal B for the first subnet connector, blue wire must be used for terminal B on all additional subnet connectors. Otherwise, the secondary panels and primary panel will not communicate.

5. Once the wires are in place, secure them in the terminal by torquing the screw to 5 lb-in. (0.6 N•m).

6. Using the same process above, secure the wires into the remaining terminals A, –, and + (see Subnet Connector Wire Installation).

7. Repeat this process as needed for all secondary address selectors.

Follow the instructions below to connect the subnetwork cabling to the secondary address selector.

1. Push the first subnet connector plug into the mating connection on the first secondary address selector (see Figure 5).

2. Facing the first secondary panelboard, connect the secondary address selector to the left control bus’s vertical bus connectors (see Figure 6).

   NOTE: If using a column-width panelboard, connect the secondary address selector to the top control bus.

3. If a left control bus is present, a secondary bus interconnect cable NF2HG3 is used to connect the right control bus to the left control bus. Push one of the connectors from the cable into the secondary bus interconnect cable connection on the secondary address selector (see Plugging in the Secondary Bus Interconnect Cable).

   NOTE: If using a column-width panelboard, use the secondary bus interconnect cable NFCWG3.

4. Push the other end of the secondary bus interconnect cable into the secondary bus interconnect cable connection on the right control bus (see Figure 7).

   NOTE: If using a column-width panelboard, connect the secondary bus interconnect cable to the bottom control bus.

5. Affix the secondary panel label to the door of the secondary panelboard. Using a pen or permanent marker, fill out the information on the label using Secondary Panel Label (see Figure 8) as an example.

6. For each secondary panelboard, repeat steps 2 through 5 as needed.

7. Fill out the primary panel label on the primary panelboard. This label contains a list of the primary panelboard’s secondary panelboards (see Figure 9).

8. Proceed with the installation of any other Powerlink components according to the installation instruction sheets provided with the component. If no other components are to be installed at this time, or the installation is complete, replace the panelboard deadfront and cover before turning on the power.
