2.3 Mounting
Ensure transmitter and sensor are securely mounted as per local regulations. The transmitter has
mounting holes to allow mounting to a wall or pole as desired. Mounting kit hardware is required when
mounting the transmitter a pole. Contact your local Net Safety representative for detailed information
on the pole mounting kits. The transmitter should be mounted at eye-level and be easily accessible for
monitoring and maintenance purposes.

2.4 Wiring
2.4.1 General requirements
Failure to follow these installation guidelines could result in death or serious injury. Ensure that only
qualified personnel perform the installation.
Electrical shock could cause death or serious injury. Use extreme caution when making contact with
the leads and terminals.
Do not open the transmitter, sensor, or junction box enclosure when in a classified area or when an
explosive atmosphere may be present unless the power to the transmitter has been removed.
Wiring codes and regulations may vary. Wiring must comply with all applicable regulations relating to
the installation of electrical equipment in a hazardous area and is the responsibility of the installer. If in
doubt, consult a qualified official before wiring the system.
When separating the sensor from the transmitter, the use of shielded cable is highly recommended to
meet electromagnetic compatibility (EMC) requirements and to protect against interference caused by
extraneous electrical or electromagnetic noise. In applications where the wiring is installed in conduit,
the conduit must not be used for wiring to other equipment.
If the 4-20 mA signal is not used, connect a jumper between the 4 – 20 mA terminal and the common
terminal to allow analog current levels to be monitored at the test jacks on the transmitter board.
In applications where wiring is installed in conduit, conduit must not be used for wiring to any other
electrical equipment.
For effective communication, Net Safety limits sensor separation to 2000 feet (600 meters) using 16
AWG wires.
Modbus RS-485 connection 2-wire mode, multipoint serial line available. Up to 16 addresses allowed.
When developing a RS-485 chain of devices, the last device in the chain requires an end of line
termination resistor (120 Ohms).
2.4.2 Terminal connection
When connecting cable wires, use a small screwdriver to gently press down and hold the spring
connector open. Insert the appropriate wire into the open connector hole, releasing the screwdriver to
secure the wire as shown in Figure 2-2.
The connector will accommodate wire sizes between 14 and 20 AWG.

Figure 2-2 Terminal connection
2.4.3 Cable choice and guidelines
Radio frequency interference (RFI) can be caused by nearby electrical devices (e.g. transformers or high
voltage equipment) as well as handheld communication devices/radios, which when activated, may
impede the proper functioning of the transmitter and sensor. Selecting the right instrumentation cable
and making proper grounding connections within the junction box will reduce or eliminate
interference. Visible symptoms of RFI include inconsistent, incorrect, and erratic LEL and ppm readings.
2.4.4 Important wiring guidelines
Gas detection instruments are an important part of a safety alarm and shutdown system. The system is
composed of:
• Detection instruments
• Customer connected equipment
• Wiring
Net Safety designs and manufactures its detection equipment under rigid quality control management
systems and makes every effort to design for the harshest of industrial environments. The other
components of the system – the customer-connected equipment and wiring – are also important
contributors to the overall quality and performance of the safety system.
It is important to implement wiring that ensures the reliability and integrity of the safety system. Field
wiring practices and the choice of cable type specified vary from project to project. Poor practices and
choices are often found to be the source of unwanted system disruptions. RFI and electromagnetic
interference (EMI) are usually very powerful disruptive forces in industrial facilities and these forces act
upon the system through the wiring.
The cable used should be a very high quality instrument grade, certified for the application conditions,
consisting of a rugged protective outer jacket, an overall electrical shield of fine braided copper or
metallic foil, and internal pairs or triads of foil shielded copper wire of suitable gauge for the power
conducted over the specified length.
The shields must be electrically continuous from the instrument junction box through other junction
boxes and finally to the connected equipment. The shield must be connected to a suitable ground sink
as specified in the instrument manual in order to protect the system from electrical disturbances.
In general, communication cables and power cables should not run in parallel for any significant length,
and should not be carried in the same cable tray. Through inductance, high currents in power cables
can induce significant ‘noise’ in communication cables running parallel alongside power cables.

2.4.5 External ground
In order to ensure proper operation of the sensor, an external earth ground is recommended. Net
Safety recommends that the external ground be connected to the grounding point on the enclosure.
2.4.6 Seals
The use of seals is recommended to further protect the system against water ingression, and
equipment should be installed according to applicable local electrical codes. Seals are especially
recommended for installations that use high-pressure or steam cleaning devices in proximity to the
transmitter.
• Waterproof and explosionproof conduit seals are recommended to prevent water accumulation
within the enclosure.
• Seals should be located as close to the device as possible and not more than18 in.(46 cm) away.
• Explosionproof installations may require an additional seal where conduit enters a non-hazardous
area; ensure conformity with local wiring codes.
• When pouring a seal, use a fiber dam to ensure proper formation of the seal. Seals should never be
poured at temperatures below freezing.
• The jacket and shielding of the cable should be stripped back to permit the seal to form around the
individual wires. This will prevent air particles and water leakage through the inside of the shield
and into the enclosure.
• It is recommended that explosionproof drains and conduit breathers be used. In some applications,
changes in temperature and barometric pressure can cause breathing which allows moist air to
enter and circulate inside the conduit. Joints in the conduit system are seldom tight enough to
prevent this breathing.
2.4.7 Analog output, isolated supply, non-isolated supply and jumper
configuration
The analog output may be powered from the main instrument power supply or a separate,
independent power supply, in which case an isolated wiring configuration is necessary. These
configurations only apply to analog and analog/HART® model transmitters.
To set a non-isolated or isolated current output, simply move the jumper/shorting jack located at JP1
near the power and output terminals, to either the non-isolated or isolated current position. For nonisolated current output, ensure pins 3 and 2 at JP1 location on the terminal board are jumpered
(shorted). See Figure 2-3 for reference. Factory standard models ship with jumper in the non -isolated
current output position.
For isolated current output, pins 1 and 2 at JP1 should be jumpered (shorted). See Figure 2-3 for
reference.
