Installation
The mating RTD Molex connection in the Junction Box is only available on OXYvisor models with Agency Approval selection “2”
(cULus CID2 and ATEX/IEC Zone 2 3G) per OXYvisor Conguration - Product Model Selection, Table 2.
Barben Optical Sensors (BOS) connect to the OXYvisor through a ber optic cable connection. The ber optic cable from the OXYvisor is easily
mated to the BOS oxygen sensor via a nger-tightened SMA coupler connection, located in the lower sensor junction box (J-Box). Both integral and
external RTD’s can be connected to the OXYvisor through the Rear (Wiring) Compartment and via the J-Box when the later connection is available.
Figures 10, 11 & 12 show some common arrangements for the OXYvisor and BOS sensors.

Figure 10 - BOS Sensor With Integral RTD Through Junction Box
When the BOS sensor is specied with an integral RTD, and the OXYvisor model is selected with Agency Approval “2” or “3”, the RTD can also be
connected through the J-Box via a Molex connector. See Figure 10.

Figure 12 - BOS Sensor And External RTD or Zone 1
For OXYvisor installations in Zone 1, where the model is selected with Agency Approval “1”, the BOS sensor (as standard) is not allowed to be
installed with integral RTD. An external RTD will be the standard recommended installation. For this case, the RTD can be wired through the Rear
(Wiring) Compartment as shown in Figure 12.
