I nstallation

NOTE: Before installing unit, verify the option label on the unit matches the
aircraft requirements for instrument voltage, lighting voltage/ color,
and panel tilt.
I nstall the Electric Attitude I ndicator within the aircraft in accordance with the aircraft
manufacturer's instructions and the following steps:
A. Refer to Figure 2.1 for installation dimensions and electrical information.
B. Ensure the available instrument panel cutout meets the requirements of the indicator.
See Fig. 2.2 for details.
C. I f a remote mounted standby battery is preferred:
1. Remove 4 screws mounting the standby battery to the rear of the indicator and
remove the standby battery.
2. Re-install the 4 screws into the rear of the indicator.
3. Mount the standby battery in a protected location inside the aircraft using
9015671 kit, oriented at any angle from horizontal to vertical. I f mounted
vertically, cable side must be down as shown in Fig. 2.4.
4. Make an extension cable, 22 AWG minimum, using the connectors provided in
9015671 kit.
D. Plug the standby battery cable into the rear of the I ndicator.
NOTE: The cable is disconnected for shipping to prevent accidental
activation and battery discharge in transit.
E. The unit may start when the battery is connected. Momentarily push the STBY PWR
button, twice if necessary, until the Red Gyro Warning flag shows. Continue the
installation after the Gyro has spun down.
F. Attach aircraft electrical system cable to the round 4-pin indicator connector and insert
the indicator into the instrument panel cutout.
G. Secure the indicator to the instrument panel using the screw sizes called out in the
mounting instructions. Length of screws will be determined by aircraft instrument panel
thickness. The aircraft manufacturer or the installation facility is responsible for supplying
appropriate installation hardware.
H. Apply the correct input power to the indicator.
I . The Gyro Warning flag (red) will be out-of-view.
J. Check to determine that indicator internal lighting is working correctly.
K. After the unit has been powered for at least a 3-minute spin-up period, press and hold
the STBY PWR button. A green light will illuminate under the word TEST, indicating the
standby battery is functioning properly. I f a red light illuminates, the standby battery will
need to be charged for 1 hour before retesting. I f the standby battery fails to pass the
short battery capacity test after 1 hour charging, a full battery capacity test must be
performed. See Sect. 2.6.1D.
