12 VAC/DC at 250 mA must be supplied to the indicator
for power. This is connected to the power terminals as
shown. If the indicator is to be powered by a transformer,
then 115 VAC or 230 VAC must be supplied to the
transformer primary (as required by the transformer type),
and the 12 VAC output of the transformer is connected to
the indicator power terminals as shown. Refer to wiring
diagram for transformer and thermocouple connections.

For long thermocouple wire runs the proper thermocouple
extension wire must be used, and the correct polarity
must be maintained. If these precautions are not
observed, the unit may not meet specifications.

Power and thermocouple wire should not be placed in
the same conduit or wiring trough. However, wires from
several thermocouples may be in the same conduit or
wiring trough.

3. Place insulator on TTD unit and attach bracket.

NOTE: Bracket is not to touch the metal surface of the
panel. The bracket must rest on the insulator. Any other
method of mounting will cause damage to the internal
operation of the TTD unit.

If shielded thermocouples are used, the shields should
be insulated electrically from the thermocouple wires and
terminated to earth ground.

Ungrounded thermocouples are required when multiple
controllers/indicators are used or if the transformer is
grounded.
