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 6 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.
