1Installation Instructions & Wiring Guide

Before you start!
Always ensure that the vessel’s power source and battery are disconnected or isolated prior
to installation. A qualified professional should carry out both the electrical and mechanicalinstallation. If in doubt please contact LUMISHORE. Refer to product support section.
Installation Instructions:
1 Using suitable screws, mount the Lumi-Hub in an accessible dry location within reach of the lights andclose to the vessel’s power supply.
2 Use the fuse table on page 6 to select the appropriate fuse size for the model of light and vessel supply
voltage. Insert the fuses securely into the fuse holders.
3 Select the Power cable following the cable gauge guide on page 5. Note : To reduce voltage drop
along the cable, keep the power wire from the Battery to the Lumi-Hub as short as possible.
4 Use a suitable wire for the switch cable (20-24AWG), the wire should be 2-Core if using a standard“On/Off” switch, or a 4-Core if using the optional “Lumi-Switch”. Note : The switch wire does not carryany current so can be over 100ft in length.
5 Follow the guides on pages 3 to 4 to select the appropriate cable gland insert for the number of lights.
The hubs can be daisy chained together if installing more than 4 lights.
6 Feed the cable through the cable glands and wire accordingly to the figure below.
LUMISHORE recommends using long nose pliers to guide the cable into the screw terminals. Checkeach wire has located correctly and has sound connection.
7 Note : Cable between the Lumi-Hub and lights can be extended using 16AWG cable. Follow the tableon page 6 to find the maximum overall cable length.
8 Tighten all cable glands and replace lid, ensure they are sealed correctly.
