A successful installation should start with careful planning including determination of
mounting location for the SL70, antenna location and mounting, connections to an altitude
data source, power, cable routing, and other required modifications.

Once the mounting location has been determined, prepare the mounting frame for installation.
If may be easier to complete the wiring harness and attach the connectors to the mounting
frame prior to installing the mounting frame in the aircraft.

ONSIDERATIONS
The SL70 is designed to mount in the avionics stack in the aircraft instrument panel within
easy view and reach of the pilot. The standard package includes the mounting frame for ease
of mounting, connections, and service of the unit. Allow an additional one inch clearance to
the rear of the mounting frame for connections and cables.

of mounting, connections, and service of the unit. Allow an additional one inch clearance to
the rear of the mounting frame for connections and cables.
For typical installations, the SL70 does not require external cooling. When mounting the unit,
leave a clearance of 1/8 to 1/4 inch between avionics to allow for air circulation.

The SL70 can use either a standard altitude gray code input from an encoding altimeter or an
RS-232 input from a serial encoder. For new installations, a serial encoder is recommended
because it simplifies the wiring and is more reliable. The SL70 can detect failures on the RS-
232 input, thereby eliminating erroneous mode C altitude replies.
