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 Ultima Gas Monitor cable through conduit opening
and wire it to the terminal block in the bottom of the sensor.
3. Verify the identity of each conductor cable and connect the
wire to the terminal block (FIGURE 1-26).

The other wire within the cable is not used. Also, it is
unnecessary to connect wire to the other terminal positions
within the remote sensor. Do not connect the shield at the
remote sensor.
4. Screw the conduit or cable grip or gland into the conduit
opening. Relieve any excess slack in the cable.
