The Southland Sensing OMD-625 Oxygen Analyzer is designed to be mounted on a wall or on a pipe
in a general purpose, Class 1 Division 1 or Class 1 Division 2 Group B, C, D area. When installed out-
doors in cold areas an optional heater is recommended as well as a heavy duty enclosure. Consider
also giving the analyzer a sun shield if it is going to be mounted in the direct sunlight.
Seals are required on the power and signal condulet entries, whether the area classification is Division
1 or Division 2. Reference your local electrical authority for the proper installation.
The analyzer is EMI / RFI protected, however it is good practice not to mount it too close to sources
of electrical interference such as large transformers, motor start contactors, relays, large pumps, etc.
Also, avoid subjecting the analyzer to significant vibration.
The analyzer has a local display, mount the unit at a suitable eye level for easy reading. Gas connec-
tions are located on the bottom of the analyzer, make sure there is room to hook up your gas lines.
The oxygen analyzer is designed for installation into either a general purpose area, or a Class 1 Divi-
sion 1 or a Class 1 Division 2 Group B, C, D area, but it is also designed so that a hazardous gas may
be introduced into the main sensing compartment. This gas may be of any group B, C or D.
The analyzer consists of two enclosures mounted on a single back panel. The small round enclosure
is explosion-proof and contains the electrical connections for the user - such as power, alarms and
analog output (Optional MODBUS). This explosion-proof enclosure also contains the power supply
and safety components for the other enclosure. The larger square enclosure contains the analytical
circuitry, the oxygen sensor and the oxygen sensor housing. This circuitry is designed for intrinsic
safety and meets requirements for Class 1 Division 1 Group B, C, D.
When installing a Class 1 Division 1 or Class 1 Division 2 device, please follow your local electrical
code should the area need to be declassified prior to installation.
