12.2 Connection Diagram

The use of an external 1A fuse is recommended. Connect the supply terminals to your aircrafts power supply. The AHRS-
1 / MAG-1 can be used on both 12V and 24V without the use of any pre-regulators. Ensure that the supply voltage will not
drop below 8V during operation as this may result in incorrect readings.
