2.3 INSTALLATION PROCEDURES
Use the following procedures to install the GH-3100 Electronic Standby Indicator and MAG-3000 or
MAG-3100 Magnetometer. After installation refer to the applicable post installation procedure for
calibration, power-up and ground testing. Mating connector and wiring instructions are located in
paragraph 2.3.3.
2.3.1 GH-3100 Electronic Standby Indicator
The following steps provide the general requirements for locating and installing the indicator in an aircraft:
1.
The indicator provides emergency aircraft attitude information. Therefore, the indicator should be
located in the instrument panel slightly below and in close proximity with the pilot’s normal line of
view. The indicator adjustment knob should be within easy reach.
2.
The indicator should be accessible for inspection, maintenance, or removal and free from instrument
panel structural flexure and excessive vibration or heat.
3.
The indicators wiring cables should not run adjacent to heaters, engine exhausts, or heat sources.
CAUTION
Improper installation of the 3 ATI mounting clamp may result in
damage to the indicator during operation due to excessive heat
build-up.
4.
Compare the space requirements of the indicator with the installation area being considered. Refer to
Figure 2-2 for dimensional requirements. It is recommended that the Mounting Clamp provided in
the installation kit (see Table 2-1) be used when installing the indicator. Refer to Equipment
Required Not Supplied (para 1.6) for connector tools.

Perform the following as necessary to install the indicator:
5.
Cut out the proper sized hole in the instrument panel in a location selected earlier.
6.
Attach 3 ATI Mounting Clamp to panel cut out using two screws (provided by installer).
NOTE
The 3 ATI Mounting Clamp provided in installation kit (refer to Table 2-1)
has a specific orientation requirement during installation. An error in
mounting clamp orientation will result in blockage of ventilation holes in the
cover of the GH-3100 and subsequently, heat buildup within the indicator
will occur.
