The feedback unit has an external ground terminal and must have a
proper ground connection to the hull. The grounding wire should be as
short as possible and at least 10 mm wide.
Note ! If the RF14XU and the indicators are powered from an unsmoothed
24V supply, the enclosed 470 μ F capacitor must be connected across
the supply voltage terminals (+, –) to avoid off-set on the indicator
reading.
