Caution: Hazardous areas must be declassified before removing the junction box cover
or replacing the sensor assembly
a) Disconnect all sensor wire connections at the J-Box, after removing power source.
b) Use a wrench and loosen the locking nut at the top of the ITM and unthread the ITM from the junction
box.
c) Feed the new IR-700 sensor assembly wires through the ¾” female NPT mounting hole and thread the
assembly into the J-box until tight and the ITM lens faces toward the front access point. Connect the
sensor assembly wires inside J-Box (Refer to Section 2.6, and Figure 14).
