The 7180 gauges support a nominal supply voltage of either 12VDC or 24VDC. The supply
voltage to the meter is isolated from the supply voltage used for the illumination. This
isolation allows the illumination to be powered from a separate power source or connected
to a common dimming control circuit for all dash mounted instruments.
The unit contains a T3-1/4 Miniature Wedge Base incandescent bulb holder with a 12 VDC or
24 VDC bulb pre-installed as per the model ordered.
A circuit breaker of 2A is recommended between the vessel power
supply source and the indicator(s) as shown in the example
installation diagrams.
All terminal wire connections to the meter should use crimped ring
or ferrule terminals, as appropriate, to ensure a secure connection
for high-vibration environments.
Control signals shown in the following figures are provided by standard control levers. Please
review the Kobelt website for all options available.
Electrical installation of the 7180 should proceed as follows:
Disconnect Power:
Turn off power at distribution panel before
beginning installation to protect installer from electrical hazards.
Proper Electrical Polarity:
Damage to the indicator can occur if input
voltage connection is reversed. Ensure proper connection of the
Positive and Negative terminals.
