2.9 Connect to ground
CAUTION: Grounding
SPX-5 Tiller 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 Tiller 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 pole of the battery (ideally at the battery itself).
