Item 6 is a shield drain wire that will not be used for interconnection. This wire should be cut off flush from the cable when the outer jacket is stripped back for interconnection of the system.

The following section is a guideline to a proper installation of the WC000001 cable. Please follow this guideline to ensure a proper installation and interconnection in the junction box.

1.Strip back at least 16” of the outer jacket of the WC000001 cable. Make sure that during this removal, the other wires are not damaged. If the insulation is damaged on one of the other wires, a potential of lighting problems can occur shortly after the system is connected.

2.Remove all the aluminum foils and braids from the exposed conductors. These will not be used for interconnection.

3.Cut off Item #6, bare shield wire, that protrudes from the cable. This wire will not be used for interconnection.

4.Connect Item #5, bare shield wire, and Item #4, #12-AWG Green wire, from all the cables to the ground lug inside the junction box. This ground lug can be found on the back plane of the junction box or at an internal locknut that has a ground screw attached. No other wires will be connected to ground.

5.Connect Item #1S, data/communication inner shield drain wire, to the other data shield drain wires from the additional data cables. Trim back the associated shield neatly. Make sure that this drain wire and the shield cannot contact the walls of the junction box or other wires. Do not connect inner shield to outer shield. Extra taping may be required for proper isolation. The inner shield should only have a connection to ground inside the SGC-60 controller.

On a typical installation, there will be a total of 5 wires that will be connected together. One from the lower junction box level, three from the flashhead cables on that level, and one for the cable going to the next level.

6.Connect Item #1A to corresponding wires in other four cables as stated above in step 5.

7.Connect Item #1B to corresponding wires in other four cables as stated above in step 5.

8.Connect the #12-AWG Black and #12-AWG White wires as required by the installation drawing set supplied with the lighting system. If the system has a 3-phase input, ensure proper connection between the 3-phase wires (typically brown, orange, and yellow) and the black and white wires from the flashhead. Proper load balancing is required on the three-phase input to operate efficiently (distribute the flashheads as evenly as possible across the phases).
