Wiring the Maretron CLMD12 Digital Switching Module correctly is crucial for its proper function within your vessel's electrical system. Here’s a step-by-step guide to help you:
-
Load Connections: The CLMD12 has two connectors for load connections. The J1 connector is designed for loads up to 12A, while the J2 connector is for electromechanical input connections. It's essential to match your load's specifications with the appropriate connector.
-
J1 Connector (Load Connections): Use the provided mating connector, which comes with 0.3-meter flying leads, for loads that draw up to 12A. Connect your loads to this connector, making sure to consider their current demands.
-
J2 Connector (Electromechanical Input Connections): Utilize the included mating connector, also with 0.3-meter flying leads, for your electromechanical input connections. The reference ground is found on pin 6 of this connector.
-
NMEA2000® Connection: The CLMD12 uses a standard NMEA2000® 5-pin micro-C CAN cable for communication. Connect the module to your existing NMEA2000® network using the appropriate cable.
-
Wiring Best Practices: Always refer to the wiring instructions found in the Maretron CLMD12 user manual. Double-check all connections to ensure they are secure, correct, and comply with safety standards.
-
Additional Notes: For OEM (Original Equipment Manufacturer) installations, the CLMD12 part number does not include flying lead harnesses. However, the retail version, CLMD12-R, does come with these harnesses.
By following these instructions and consulting the Maretron CLMD12 user manual's wiring diagram, you can successfully integrate this digital switching module into your boat's electrical system.
