Installation
Explosion-proof Delta F
Oxygen Cells
Figure 1-20 below shows the explosion-proof oxygen cell. The
oxygen cell has a set of sensing and secondary electrodes that are
wired to a terminal strip in the explosion-proof enclosure. Connect
the explosion-proof oxygen cell using a four-wire shielded cable.
Connect one end of the cable to the
OXYGEN
terminal block on the
back of the electronics unit and the other end to the terminal strip in
the oxygen cell enclosure. Feed cable wires through an opening in the
side of the explosion-proof enclosure. Use Table 1-8 below to make
oxygen cell connections.
IMPORTANT:
To maintain good contact at each terminal block and
to avoid damaging the pins on the connector, pull the
connector straight off (not at an angle), make cable
connections while the connector is away from the
unit, and push the connector straight on (not at an
angle) when the wiring is complete.
