4. Setup and Installation
Proper installation is crucial for the safe and reliable operation of your power inlet.
- Select Location: Choose a mounting location that is easily accessible, protected from excessive moisture, and allows for proper cable routing.
- Prepare Mounting Surface: Cut an appropriate opening for the inlet body. Refer to the product template (if provided with packaging) for exact dimensions.
- Wiring:
- Ensure shore power is disconnected at the source.
- Connect the appropriate gauge marine-grade wiring to the inlet terminals. Follow the wiring diagram provided with the product or consult a qualified electrician.
- Utilize the integral strain relief within the rear enclosure to secure the wiring, complying with ABYC requirements.
- Mounting: Secure the inlet to the mounting surface using appropriate fasteners. Ensure a watertight seal around the perimeter of the inlet.
- Final Check: Before restoring power, double-check all connections for tightness and correct polarity.
5. Operating Instructions
Connecting and disconnecting your shore power cord using the Easy Lock™ system.
- Connecting the Cordset:
- Lift the hinged cover of the power inlet. The cover is designed to stay open.
- Align the cordset (equipped with an Easy Lock™ locking ring) with the inlet.
- Insert the cordset into the inlet.
- Turn the locking ring less than a quarter turn clockwise. The tabs on the locking ring will engage with the inlet, creating a positive, watertight connection.
- Disconnecting the Cordset:
- Ensure power is disconnected at the source (e.g., circuit breaker on the boat).
- Grasp the locking ring of the cordset and turn it counter-clockwise to disengage the tabs.
- Pull the cordset straight out from the inlet.
- Close the hinged cover to protect the inlet when not in use.
6. Maintenance
Regular inspection and maintenance will ensure the longevity and safe operation of your power inlet.
- Periodic Inspection: Regularly check the inlet for any signs of corrosion, damage, or wear. Pay close attention to the contacts and the locking mechanism.
- Cleaning: Clean the exterior of the inlet with a mild soap and fresh water solution. Avoid abrasive cleaners or solvents.
- Contact Care: Ensure electrical contacts are clean and free of debris. Do not use lubricants or dielectric grease unless specifically recommended by Marinco.
- Cover Functionality: Verify that the hinged cover opens and closes smoothly and provides a secure seal when closed.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power at the boat | Shore power not connected properly; tripped breaker; faulty cordset. | Ensure cordset is fully engaged and locked. Check shore power pedestal breaker and boat's main breaker. Inspect cordset for damage. |
| Cordset difficult to connect/disconnect | Debris in inlet; damaged locking ring; cross-threading. | Inspect inlet for obstructions. Ensure proper alignment before turning the locking ring. If damaged, replace the cordset or inlet. |
| Water ingress around inlet | Improper installation seal; damaged gasket; cordset not fully locked. | Re-seal the inlet during installation. Check and replace any damaged gaskets. Ensure cordset is fully engaged and locked. |
