WARNING
Before removing the cover of an explosion-proof Ultima
Remote Sensor, verify that the surrounding area does not
contain a flammable mixture of combustible gas and air
since a source of ignition is exposed; otherwise, an explosion
may occur if a metal object contacts the circuitry and
produces sparks.
2. Route the cable from the Ultima Gas Monitor through the
conduit opening and wire it to the terminal block in the
bottom of the sensor.
3. Verify the identity of each conductor of the cable and connect
the wire to the terminal block (FIGURE 1-23).
