Mounting Antenna through a Knockout
(optional)
It is possible to remotely mount the TTX antenna so
that it protrudes through the TEC enclosure using a
Heyco® sealtite fitting (part number 550-074). Follow
the installation procedure in the Installation
Instructions provided with the Heyco sealtite fitting.
Connecting Communications and Power
1.
Connect the RJ11 communications line from
the TTX to the RTS/MMI connector on the TEC
(Figure 1).
2.
Connect the TTX power wires as follows:
a. If possible, connect the TTX power wires
directly to the TEC H (hot, 24 Vac, red) and
C (common) power terminals (Figure 1).
b. If direct connection to the TEC power
terminals is not possible, locate the
jacketed 24 Vac TEC power wires from the
transformer. Connect the TTX power wires
to the TEC power wires using the power
connectors provided. See Figure 1.
NOTES:
1. The 3M Scotchlok power connector is
an insulation displacement connector.
Therefore, removing wire insulation is
not necessary.
2. The 3M Scotchlok power connectors
can be used one time only. Once they
are clamped in place, they cannot be
removed and reused. Additional 3M
Scotchlok power connectors are
available from W.W. Grainger, Inc.
(part number 4YT73) via the Field
Purchasing Guide.
The installation is now complete.

CAUTION:
When the TEC, TTX,
and FLNX are
connected to the same
24 VAC power supply,
an isolation transformer
is needed between the
TTX and the power
supply
