CAUTION: Grounding
The SPX-5 Wheel system ground MUST be connected to ship’s
ground. Failure to connect to ship’s ground may cause it, or other on-
board electronics to malfunction.
To ground your SPX-5 Wheel system:
•
Use a dedicated earthing plate (e.g. dynaplate) in contact with the water.
•
Use flat tinned copper braid, 30 A rating (1/4 inch) or greater. Equivalent stranded
wire diameter 4mm or greater
•
Keep the length of the earth braid as short as possible.
Note:
If you cannot connect to a dedicated earthing plate you may connect ground to the nega-
tive terminal of the battery (ideally at the battery itself).
