Note: To avoid damage to the unit, store the TTDM module in its
cardboard box until construction is complete.
Select the mounting position.
Choose a location indoors where the module will be protected from
the elements and temperature extremes.
• Remove the module from its carton. Do not remove the protective film
from the membrane on the front of the unit.
• Open the enclosure door using a flat-blade screwdriver or a coin.
Important: The TTDM is an electronic unit. During installation, take
the following precautions to avoid damage to its electronic components:
• Handle with care, avoid mechanical damage.
• Keep the electronics dry.
• If handling circuit boards, hold them by their edges to avoid physical
contact with electronic components.
•Avoid exposure to static electricity.
•Avoid contamination with metal filings, liquids, or other foreign matter.
Installing the TTDM
WARNING: Ignition hazard. Do not mount the TTDM unit in a
hazardous location. Sensing cable connected to the TTDM may (subject
to approvals restrictions) be located in hazardous locations, but the
module itself must be in an ordinary area.
Note: The TraceTek sensing circuit is power limited, so the TraceTek
leader or jumper cable and the power supply cable must not run in
the same conduit.
