1. INSTALL THE CONTROL BOX

Use the box itself as a template to determine the mounting 

hole footprint. Install the box to a solid, stable surface 

capable of supporting four times the weight of the box, or 

about 20 pounds. Use all four mounting holes. Install the 

control box to the wall using heavy-duty 1/4” or 6.3 mm 

fasteners long enough to fasten the box securely. Do not 

fully tighten mounting hardware at this time. Leave the 

mounting hardware loose enough to work the conduit 

into place. Hardware will be fully tightened following 

installation of the conduit.

2. CONNECT THE SUPPLY AND LOAD

Feed the Input Supply (Input Power) and the Load (Heater 

Cable) through the Conduit Entry Hole in the enclosure as 

shown, then connect the leads, as shown in the Figure 3. 

Line is black; neutral is white; ground is green.

Note:

 Both the power and the load require a #10 AWG wire.

3. INSTALL THE TEMPERATURE SENSOR

The GPT 130 can use either a thermistor (provided), or 

a  2–,3–,  or  4–wire  RTD  sensor. The  configuration  of  the 

DIP switches must match the type of RTD sensor wiring 

connection. 

Thermistor (25076)

The GPT 130 comes with a thermistor temperature sensor 

with a 20 ft. jacketed cable thathas an operating range 

of −40 °F to 230 °F (−40 ˚C to 110 ˚C). See the diagram 

below  for  proper  wiring  and  DIP  switch  configuration 

when using a thermistor sensor. Refer to Figure 4.

RTD

The unit can use an RTD sensor for applications requiring 

a wider temperature range. The GPT 130 can operate with 

2–, 3–, or 4–wire RTD sensors. Refer to Figure 4.

Note:

 The sensor must be selected in the Sensor Type 

parameter setting screen also.

Perform the following steps with the circuit breaker to the unit OFF. The TRACON GPT 130 is permanently 

connected equipment and does not have an internal disconnect device. When power is applied, the system 

will start.
