4. BLACK BOX INSTALLAION
1. Select an area with sufficient ventilation for the mounting of the black box in order to prevent the
module from overheating. You may mount the black box in a horizontal or vertical position. If the
black box is mounted in a vertical position, do not mount the module with the harness exit points
directly facing up to prevent water collecting in these areas.
2. Please refer to the diagram below for the mounting screw hole positions. Always use the shortest
length of screw possible.
3. During installation, use the 4 rubber mounting stoppers (included in the package) for the bottom of
the module. This provides clearance from surface moisture and provides sufficient ventilation for
the heat sink.
4. Extension wires/cables may be needed to route the harness and cable throughout the vessel.
Note: Retain some slack in the harness/ cables to prevent damage to the wires. It is recommended
relieve stress in all cables and harnesses.
5. Always read through the wiring diagram in this manual first, and follow all the wiring diagrams
carefully. The connections should be secured and insulated with crimp connectors or electrical
tape to ensure proper connections.
6. Once the wiring connections are completed, connect the negative terminal on the battery, turn the
vessel accessory ON and power on the unit to check if it is operating correctly. If abnormalities
occur, disconnect the battery negative terminal, recheck all wiring and try again. Please refer to the
troubleshooting section for assistance.
