2.
[nsert and secure the led (+) wire to terminal 5 of the
space temperature sensor terminal block.
3. [nsert and secure the white (ground) wire to terminal 4 of
the space temperature sensol:
4. Insert and secure the black (-) wire to terminal 2 of the
space temperatme sensor
IMPORTANT: The cable selected for the RJll
connector wiring MUST be identical to the CCN
communication bus wire used for the entire network.
Refer to Table 11 for acceptable wiring.
5. Connect the other end of the communication bus cable to
the remainder of the CCN communication bus.
NOTE: The Energy Management Module (EMM) is required
for this accessoly.
TRANSDUCERS -- There are four pressure transducers per
circuit, and two different types of transducers: low pressure
(green connector) and high pressure (black connector).
Ix>w Pressure Type: Suction Pressme Transducer (SPT), Econ-
omizer Pressure Transducer (EPT).
High Pressure Type: Dischmge Pressure Transducer (DPT),
Oil Pressure Transducer (OPT). See Fig. 29 for transducer
locations.
