II Monitor/Less Sensor; otherwise, electrical shock could occur.
Before removing the cover of an explosion-proof Toxgard II Remote
Sensor Module, 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.
Toxgard II Remote Sensor Modules (excluding the combustible
models) are supplied with 50 feet of cable. This cable has a
connector on one end which plugs into its mate within the
Toxgard II Monitor/Less Sensor. The other end of the cable can
be cut to the exact length needed.
The combustible Remote Sensor Module is wired with a
three-conductor cable. This cable can be acquired locally.
Terminal strips within the Remote Sensor Module and the
Toxgard II Monitor/Less Sensor permit easy wiring of this cable.
"
CAUTION
When installing a Toxgard II Remote Sensor Module with its mating
Toxgard II Monitor/Less Sensor, follow National Electrical and local
procedural Codes; failure to do so can result in an unsafe condition.
Maximum distance between the Toxgard II Remote Sensor and
the Monitor is 50 feet. Do not splice additional cable to the
supplied cable or run more than 50 feet of user-supplied cable.
For Combustible Models
Locate/acquire the proper length of three-conductor cable. TABLE
1-3 shows recommended wire gauge for the distance between
the Remote Sensor and the Toxgard II Monitor/Less Sensor.
Table 1-3. Wire Gauge Vs. Distance Between Units
DISTANCE WIRE GAUGE
UP TO 15 FEET 16 AWG
UP TO 25 FEET 14 AWG
UP TO 50 FEET 12 AWG
TABLE 1-4 lists several suppliers of 12-AWG cable. If there is a
possibility of electrical interference from external sources (such as
large motors, welders, electrical heaters, etc.) use shielded cable.
The preferred colors of conductors within the cable are black (K),
green (G) and white (W). If splices are necessary, solder and
insulate each conductor; then, wrap entire splice with suitable
electrical tape or covering. Do not use wire nuts or fasteners.
