Installation Instructions
The LonWorks Carrier Translator with LON FT-10A communication (33CNTRANLON), shown below,
is a microcontroller-based module that provides the ability to easily interface Carrier CCN controllers to
third party non-Carrier control equipment. The LonWorks Carrier Translator provides CCN to
LonWorks FT-10A ANSI/EIA-709.1 protocol conversion.

Installation Procedure
1. Install the Carrier Translator printed circuit board into the equipments CCN controls section and
secure by inserting 4 sheet metal screws through the boards integrated standoffs.
2. Connect a field supplied 24 Vac (3 VA minimum) transformer to the power connector.
Note 1:
The power can be shared with a single CCN controllers 24 Vac transformer provided
that you ensure there is sufficient VA available on the existing transformer. The
Carrier Translator provides an isolated communications port that allows for power
sharing with one other Carrier CCN controller that utilizes 24 Vac.
Note 2:
It is recommended that you provide a way to cycle power to the Carrier Translator
without disconnecting wires.

3. If the CCN network consists solely of this Carrier Translator and its associated CCN controller,
wire the Carrier Translators non-removable CCN communication connector to the CCN
controllers CCN communication connector.
If the CCN network consists of multiple Carrier Translators and multiple associated CCN
controllers, wire the CCN communication bus in accordance with all CCN network standards
and address the Carrier Translators and CCN controllers appropriately.
