5. Re-install the cover on the Ultima Remote Sensor.
"!
WARNING
Do not let the cover remain off of an explosion-proof Ultima
Gas Sensor. Since a source of ignition is exposed, an
explosion may occur if a metal object contacts the circuitry
and produces sparks in an atmosphere of combustible gas.
For Toxic Gas and IR Combustible Models
Fifty feet of cable is supplied with the unit. This cable has a
connector on one end which plugs into its mate within the Ultima
Gas Monitor/Less Sensor. The other end of the cable can be cut
to the exact length needed. Do not run more than 50 feet of
cable or splice on additional cable.
At the Ultima Gas Monitor/Less Sensor Location
If your installation is in an explosion-proof classified area, see
FIGURE 1-24. Appropriate wiring conduit must be used between
the Ultima Gas Monitor and the Ultima Remote Sensor. The
cable must be routed through the conduit.
Conduit may also be needed in areas where large amounts of
electrical noise is expected.
If your installation is in a general purpose area, you can use a
sensor cable grip. Follow your local electrical wiring codes. cut
the wire to the proper length needed for your installation. Trim
back the insulation, shield and the un-insulated wire. Use the
markings on the conductors at the end of the original cable or
see FIGURE 1-27 or FIGURE 1-28 for colors of wires that are
needed.
