Junction Box
Use the junction box to install the H
2
S transmitter at a mounting site that is remote from
the controller. The junction box protects the amplifier and wiring connections made to the
amplifier. Use the top 3/4’’ conduit hub to connect wiring from the amplifier to the
controller. Use the cover on the front of the junction box to access the interior of the
junction box. Three spacers installed on the back of the junction box control the distance of
the junction box from a mounting surface and ensure that there is enough room to install a
calibration cup on the detector during calibration.
