Grounding in a mobile installation like a boat requires careful attention to detail to ensure safety and compliance.
Understanding Mobile Grounding:
-
In a boat, grounding serves to protect against electrical shocks and ensure safe operation of the MultiPlus-II. Since boats are isolated from the ground, the grounding system must be self-contained.
Grounding to the Hull or Grounding Plate:
-
Identify a suitable grounding point on your boat. This could be the hull (if it’s metal) or a specially installed grounding plate.
-
The grounding point should be free of paint, corrosion, and should have good electrical conductivity.
Connecting the Ground Wire:
-
Use a grounding wire to connect the MultiPlus-II 230V to the grounding point. This wire should be of appropriate gauge to handle potential fault currents.
-
Securely attach one end of the grounding wire to the grounding point on the hull or grounding plate using bolts, nuts, and washers, ensuring a strong mechanical and electrical connection.
-
Connect the other end to the grounding terminal of the MultiPlus-II.
Shore Power Considerations:
-
When connected to shore power, the grounding system of your boat should align with the shore power’s grounding to prevent potential electrical hazards.
-
Use an isolation transformer when connected to shore power to avoid galvanic corrosion and ensure safe grounding.
Testing the Grounding System:
-
Once connected, use a multimeter to test the grounding system for continuity and proper resistance.
-
Regularly inspect and maintain the grounding connections to ensure ongoing safety and effectiveness.
Additional Safety Measures:
-
Install appropriate circuit protection devices like fuses or circuit breakers to safeguard against electrical faults.
-
Regularly inspect the electrical system, including the grounding connections, for signs of wear, corrosion, or damage.

In a mobile installation, such as in a vehicle or boat where the shore connection might be interrupted, it’s important to ground the casing of your MultiPlus-II 230V to the chassis of the vehicle or to the hull or grounding plate of the boat.
This will provide a reliable ground when the shore connection is disconnected and is essential for safety.
