Electrical
Information
The sensor probe lead wire between
the sensor probe and the module
can be separated by cutting the two
wire probe lead leaving equal
lengths of wire on each device; the
sensor probe and the sensor
module. Note this sensor and
module are matched and must
remain together or inaccuracy may
occur. These wires can then be
spliced to with two 14-18 AWG 600V
wires of sufficient length to reach the
desired outdoor location, maximum
length 1000 feet (305 meters). The
module four-wire bus must be
connected to the UCP four-wire bus
using the Trane approved
connectors provided.
The sensor will be configured (given
its identity and become functional) at
start-up when the serviceman
performs the start-up configuration.
It will not be operational until that
time.
System Control
Wiring
Note: If shielded cable is used to
extend the sensor leads, be sure to
tape off the shield wire at the
junction box and ground it at the
UCP . If the added length is run in
conduit, do not run them in the same
conduit with other circuits carrying
30 or more volts.
CAUTION
Electrical Noise!
MAINTAIN AT LEAST 6 INCHES
BETWEEN LOW-VOLTAGE (<30V)
AND HIGH VOLTAGE CIRCUITS.
Failure to do so could result in
electrical noise that may distort the
signals carried by the low-voltage
wiring, including the IPC.
