Use the following steps to install a Trillium Compact in the Carrying Case / Insulating Cover for
insulating purposes at the installation site:
1. Prepare a flat installation surface.
2. Secure the cable to the side of the seismometer with a tie wrap (see Figure 3-4 below).
3. Use tape or a heavy object to strain relieve the cable on the installation surface.
4. Use your preferred method of aligning and leveling the seismometer (see "Aligning and
Leveling a Trillium Compact in a Vault Installation" on page39).
If you are burying the Trillium Compact and its insulating cover, pull all of the foam out
of the cover. Retain these pieces of foam for future installations and transport. See
"Alignment, Leveling, and Placement Features" on page36 for more information on
buried installations.
