1.3.6 Handling the Hazardous Area OCX 8800
It is important that printed circuit boards and integrated circuits are handled only when adequate anti-static
precautions have been taken to prevent possible equipment damage.
The Hazardous Area OCX 8800 is designed for industrial application. Treat each component of the system with
care to avoid physical damage. The probe may contain components made from ceramics, which are susceptible
to shock when mishandled.
1.3.7 System Considerations
Prior to installing your Hazardous Area OCX 8800, make sure you have all the components
necessary to make the system installation. Ensure all the components are properly integrated
to make the system functional.
After verifying that you have all the components, select mounting locations and determine
how each component will be placed in terms of available line voltage, ambient temperatures,
environmental considerations, convenience, and serviceability. Figure 1-3 shows a typical
system wiring for a system with integral electronics. Figure 1-5 shows a typical system wiring
for a system with remote electronics. Simplified installations for the Hazardous Area OCX
8800 are shown in Figure 1-4 and Figure 1-5. Figure 1-6 shows the dimensions for the
optional sample tube support. Figure 1-7 shows the dimensions for the optional in-situ
filters. Figure 1-8 shows the optional panel mounted blowback.
A source of instrument air is required at the Hazardous Area OCX 8800 for reference air,
dilution air, and eductor air. Since the OCX 8800 is equipped with an in-place calibration
feature, provision should be made for connecting test gas tanks to the OCX 8800 when it is to
be calibrated.
NOTE
The electronics module is designed to meet Type 4X and IP66 and the electronic components are rated to
temperatures up to 185 °F (85 °C).
Retain packaging in which the unit arrived from the factory in case any components are to be shipped to another
site. This packaging has been designed to protect the product.
