Section 2: Installation
2.1 Unpacking and inspection
Carefully remove all of the components from the packaging and verify them against the enclosed packing list. Inspect all components for any obvious damage suc h as b r oken or loose parts. If you find any components missing or damaged, notify your local Net Safety representative or the factory immediately.
Recycling of packaging should be taken into consideration and disposed of in accordance with local and national legislations/regulations.
2.2 Dimensions
The following drawing outlines the dimensions of the junction box. Measurements are in inches and millimeters. As a standard, the junction box is provided with one (1) conduit plug.
Figure 2-1 Net Safety Junction Box Dimensional Drawing
2.3 Mounting
Three (3) conduit entries located on the junction box body are available in ½ inch–14 NPT, ¾ inch–14 NPT, or M20 × 1.5 mm thre ad. The standard of fe r i ng i s ¾ inch NPT, consult your Emerson Process Management/Net Safety representativ e fo r availability of other conduit entry sizes. Connection of conduit, cable glands, sensors, or detectors to these conduit entries should be done so by use of tools. A 6 mm Hex Key is required for installing or removing conduit entry plugs. Use a 1.5 mm Hex key to tighten the locking Hex screw securing the top cover. The junction box has mounting holes for installing directly on a wall or to a pole, with the aid of a pole mounting kit, as desired.

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 makin g c o ntact with the leads and terminals.
Do not open the junction box enclosure when in a classified area or when an explosive atmosphere may be present unless the power to the sensor has been removed.
Prior to touching the painted enclosure surface or non-metallic labels, dispel any charge in your body or equipment by touching a grounded metal surface to prevent the generation of

shield cable is recommended. Connection of conduit or cable glands should be done so by use of tools. In applications where the wiring is installed in conduit, the conduit must not be used for wiring to other
electrical equipment. The junction box may be susceptible to ESD. Refer to
handling of this equipment. The temperature rating of the wires co nnected to the junction box must be greater than

2.4.1 Device separation distance
The maximum separati o n distan ce betw een the junction box and the connected device is limited by the resistance of the c o n nected wiring, which is a function of the gauge of the wire being used. Net Safety recommend s that separation must not exceed 20 00 feet (610 meters) while using 16 AWG (1.31
2
) wire. The Net Safe ty M illennium SC1100 co m b ustible sensor should not be separated mo r e than
mm 150 feet (46 meters). Refer to Section 6 for wire gauges and resistance values.
2.4.2 Seals

Water-proof and explosion-proof 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 than 18-in. (46cm) away; seal all conduits within 18-in. (46 cm). Consult the local electrical code for specific requirements.

MAN-0081, Rev 5 June 2016
Explosion proof installations may require an additional seal where the 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. Always refer to the seal manufacturers r ec ommendations.
The jacket and shielding of the cable should be stripped back to permit the seal to fo r m ar o un d t he individual wires. This will prevent air, gas, and water leakage through the insi d e of the shield and into the enclosure.
It is recommended that explosion-proof drains and conduit breathers be used. In some applications, alternate changes in te mperature and bar o m etr ic 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 breathin g.

Review the following checklist prior to turning the power on to the junction box after installation h as been completed:
Ensure that the junctio n box is properly and firmly mounted.
Ensure that stopping plugs are securely tightened on any unused conduit entrie s .
Ensure that the junction box is not obstructed such that it is accessible.
Ensure adherence to applicable local guidelines and requirements on wiring and sealing of equipment in
hazardous and non-hazardous areas.
Ensure that proper shielding and grounding practices are adhered to and local codes are being followed.
Check system operational voltage and conditions and ensure that they are within the applicable specifications of
the connected devices.
Verify wiring at all termination and junction points (junction box and power supply ) .

Section 4: Maintenance
4.1 Troubleshooting
The junction box is not designed to be repaired in the field. If problems should develop, first check for faulty wiring and confirm proper voltage to the junction box. If problems persist, contact Net Safety’s technical support department first by phone to try and resolve any issues. If issue s c annot be resolved, please follow the procedure in Section 1.3 Return of material.
4.2 Storage
The sensor and its electronic components/parts should be stored in locations free from dust, liquid spills, contaminants, and moisture. The storage temperature should be well within the limits of the certified temperatures of the equipment. See Section 7 for certified temperatures.
4.3 Spare parts and accessories

MAN-0081, Rev 5 June 2016
Section 5: Electrostatic sensi ti ve d evi ce
Definition: Electrostatic discharge (ESD) is the transfer, b etwee n bo di es, of an electrostatic charge caused by direct contact or induced by an electrostatic field.
The most common cause o f ESD is physical cont act. Touching an object can cause a discharge of electrostatic energy. If the charge is sufficient and occurs near electronic components, it can damage or destroy those components. In some cases, damage is instantane o us and an immediate malfunction occurs. However, symptoms are not always immediateperformance may be marginal or seemingly normal for an indefinite period of time, followed by a sudden failure.
To eliminate potential ESD damage, review the following guidelines:
Handle boards by the sid es taking care not to touch electronic components.
Wear grounded wrist o r foot straps, ESD shoe s o r he el grounders to dissipate unwanted static e nergy.
Prior to handling boards, dispel any charge in your body or equipment by touching a grounded metal surface.
Ensure all compone nts are transported an d st o r e d in ESD safe packaging.
When returning boards, carefully package i n t he original carton and static protective wrapping.
Prior to touching the painted enclosure surface or no n-metallic labels, dispel any charge in your body or
equipment by touching a grounded metal surface to prevent the generation of a spark.
Ensure ALL personnel are educated and trained in ESD Control Procedures.
In general, exercise accepted and proven precautions normally observed when handling electrostatic sensitive devices.
