Section 2: Installation
2.1 Unpacking and inspection
Carefully remove all of the components from the packaging and verify t hem against the enclo sed
packing list. Inspect all components for any obvious damage such as broken or loose parts. If you find
any components missing or damaged, notify your local Net Safet y r ep r e sentative or the factory
immediately.
2.2 Dimensions
The Millennium II Basic transmitter enclosur e i s available in alumi num (6061) and stainle ss steel
(SS316). Dimensions ar e p rovided in Figure 2-1 below.
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.

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 at mosphere may be present unless the p ower to the transmitter has been removed.
Wiring codes and regulations may vary. Wi r ing

doubt, consult a qualified official before wiring the system.
When separating the se nsor

2.4 Wiring
2.4.1 General requirements
must comply with all applicable regulations relating to
from the transmitter, the use of shielded cable is highly recommended to
If the 4-20 mA signal is not used, c o nnect 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 comm uni c ation, Net Safety li m i t s sensor separation to 2000 f eet (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 devi c e i n t he c hai n r eq uires an end of line
termination resisto r (120 Ohms).
2.4.2 Terminal co n nection
When connecting cable wir es, use a small screwdri v e r to gently press down and ho l d 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.
. In applications where the wiring is installed in conduit,
The connector will ac c o m modate wire sizes be tween 14 and 20 AWG.

2.4.3 Cable choice and guidelines
Radio frequency interference (RFI) can be caused by near by el ectri cal dev i ces (e.g. transformers or high
voltage equipment) as well as handheld co m m unication devic e s/rad i os, 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 impor tan t p art of a safety alarm and shutdown system. T he sy ste m is
composed of:
• Detection instruments
• Customer connected equipment
• Wiring
Net Safety designs and manufactures its detection equipment under rigid q ual i ty c o ntr o l m anagement
systems and makes every effort to design fo r the har shest of industrial environments. T he 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 fou nd to be the source of unwante d system disruptions. RFI and electromagnetic
interference (EMI) are usually very powerful disruptive fo rces in i ndustrial facil iti es a nd these forces act
upon the system thro ug h 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 g r o u nd si nk
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 carr ied i n the same cable tray. Through inductance, high currents i n 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 grou nd is recommended. Net
Safety recommends that the external gro und b e co nnected to the grounding point on the enclosure.
2.4.6 Seals
The use of seals is recommended to further pr o te ct the system against water ingression , and
equipment should be installed according to applicable local electrical codes. Seals are especi ally
recommended for installations that use hi gh-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 locat ed as c lose to the device as possible and not more than18 inches (46 cm) a way
• Explosionproof installations may require an additional seal where conduit enters a non-hazardous
area; ensure conformity with local wiring codes
• When pouring a seal, u se 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 temperatur e and barometric pressure can cause breat hing which allows mo i st ai r to
enter and circulate inside the conduit. Joints in the conduit system are seldom tight enough to
prevent this breathin g
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 out p ut, e nsure pins 3 and 2 at JP1 l o cation on the terminal board are jumpered
(shorted). See Figure 2-3 for reference. F ac tory standard models ship with jumper in t he n o n -isolated
current output position.
For isolated current output, pins 1 and 2 at JP1 should be jumpered (shorted). See Figure 2-3 for
reference.

2.6 Remote mounting of sensor
When necessary to mo unt sensor remotely ( sep arated from transmitter) by way of junction box and
conduit, it is important that the installer follow the necessary requirements and guidelines relating to
sensor separation a nd c able selection. See Figure 2-6 for typical remote mounting of the sensor.
When sensors are bein g m ounted remotely, co nsult the multi-purp o se junction box manual
(MAN-0081) for wiring instructions. Alway s e nsure that the transmitter is supplying 10.5 - 32 VDC
across the sensor po we r te rminals of Net Safety junction box (JB-MPD-A/S).
The maximum distan ce b etween the sensor and tr ansmitter is limi ted b y the r e si stance of the
connecting wiring, which is a function of the gauge of the wire being used. For effective
communication, Net Safety limits the separation distance between senso r and tr ansmitter to 2000 feet
(600 meters) using 16 AWG wire. See Section 10 for information on wire gauge and resistance.
