Power supply
– if you are going to run the unit off solar power, using a battery, you need to size both the
battery and the solar panel correctly. The analyzer draws about 30mA at 14.4 volts, but if you select the 4-
20mA output option this will go up to about 60mA.
Location:
The unit is designed to be mounted on a wall or on a 2” pipe in a general purpose, Class 1 division 2 Group
C,D area. It must not be mounted outdoors unless precautions are taken to avoid exposing it to
temperature extremes or water ingress.
It MUST NOT be enclosed in another sealed enclosure such as a
NEMA 4 box
, as this will violate its safety design. A vented box or enclosure is acceptable. Although the unit
is RFI protected, do not to mount it close to sources of electrical interference such as large transformers,
motor start contactors, relays etc. Also avoid subjecting it to significant vibration – don’t mount it on the
side of a compressor!
Give yourself enough clearance on the right side that you will not have a hard time connecting the gas lines.
Safety Considerations:
The unit is designed for installation in either a general purpose 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 its main compartment. This gas may be
any group B,C or D gas such as natural gas.
The enclosure is vented so that it can be considered as a Class 1 Division 2 area. It MUST NOT be mounted
in a Class 1 Division 1 area, or inside another sealed box.
Flashing Display:
A flashing display indicates that the unit is measuring percent ranges. When the unit is measuring ppm
levels of oxygen its display will be steady.
