2.1 Installation
Mount the instrument at the appropriate height for the gas to be detected,
taking into account the density of the gas, air flow patterns in the room, and
personnel considerations. Responsibility for correct placement of the
Polytron FX rests with the end user; if in doubt about placement, consult with
Draeger application engineers.
Polytron FX is a three-wire device powered by 16 to 30 V DC. Wiring terminals
are located on the back of the PCB; pull out the bezel, by grasping the notches
on either side of the display with your fingers and pulling up (Figure 2).
