Wireless Communications Interface
Installation Instructions

DESCRIPTION

The nVent RAYCHEM Elexant 9200i is a Wireless Communications Interface that provides an alternative solution to hardwired Remote  Monitoring and Configuration of Electric Heat Tracing (EHT) systems. It integrates with nVent RAYCHEM Supervisor software and Electric Heat  Trace (EHT) controllers, helping reduce TIC/TOC of a project.
The Elexant 9200i product line consists of the following:

• Standalone enclosures
• A wireless communications option within a given Control Panel
• External antenna packages

A minimum of two radio transceivers are required to establish a network. Standalone enclosures can be configured in many ways, enabling the  customer to choose from a range of options:
enclosure material, radio frequency, and antenna type.

TOOLS REQUIRED

Small flat-blade screwdriver (terminal driver), wire strippers and utility knife, and/or wire cutters.

SUPPORTING INFORMATION

Further information pertaining to transceiver hardware and software can be found within associated manufacturer’s documentation.

2. Further information pertaining to specific regional information can be found within the manufacturer’s documentation.

WARNING:
This component is an electrical device that must be installed correctly to ensure proper operation and to prevent shock or fire.

GENERAL

ENVIRONMENTAL

MOUNTING THE ELEXANT 9200I ENCLOSURE

The ideal mounting method is to secure the enclosure to channel strut, or other structural components, using the included mounting hardware.
Typical enclosure dimensions: inches [mm].

CONNECTIONS AND INDICATORS

A. TB-1 Wiring

B. TB-2 Wiring

Note 1: To provide isolated earth for comm shield, remove jumper between IE & PE.
C. Antenna Connection
Note: Internal antenna connections made at factory. An external connection applies if using an external antenna package; such a connection method is provided.

D. Status LEDs – Radio transceivers

WARNING:
Shock Hazard. Disconnect from live voltage prior to accessing terminals

SPECIFIC CONDITIONS OF SAFE USE

• The enclosure of the device shall be fitted with a locking mechanism such that it is only accessible with the use of a tool
• To maintain an internal pollution degree 2 environment, after opening the enclosure, make sure there is no visible condensation or dust. Power the device and let it heat up for 5 minutes before closing the enclosure door
• Only install in areas with low risk of mechanical impact
• Enclosure openings must be filled by equipment marked for use in ATEX / UKEx / IECEX Zone 2 areas, and match or exceed the IP rating of the enclosures. General Guide to Cable Entry Positions into Cable Gland or Enclosure Side:
  • Maximum hole diameter is major thread diameter of cable gland plus 0.7 mm (.03″)
  • Minimum material to be maintained between holes: Glands M16 through M32: 15 mm (0.59″) Glands M35 through M75: 20 mm (0.79″) Glands M75 through M100: 35 mm (1.38″). Prior to making holes in the enclosure wall or gland plate, verify that the selected gland will not interfere with the sealing washer and locknut
  • Select a gland for the correct application with the proper certifications. Make certain all cable gland accessories are included for through hole installation. Additional accessories may include locknut and sealing washers
  • Install the gland in accordance to the manufacturer’s instructions
  • Holes must be located to prevent sealing washer and locknut from interfering with gasket
• Externally mounted antennas and accessories must be suitable for ATEX / UKEx / IECEX Zone 2 areas, and match or exceed the IP rating of the enclosures
• The fuse for incoming power shall be considered user replaceable. Refer to Enclosure Drawing Bill of Materials for the correct Current Rating, Model, and Part Number of the fuse. Prior to replacing the fuse, disable or disconnect from power.
  Upon replacing the fuse, remove the fuse plug / housing, replace the fuse per note above, close and re-seat the fuse plug /housing securely

WARNING: Explosion Hazard – Substitution of components may impair suitability for Class I, Division 2 hazardous and nonhazardous locations
