  • Page 2: Installing The Nae/Nie

    (NIE) monitors and supervises networks of devices that typically control Heating, Ventilating, and Air Conditioning (HVAC) equipment, lighting, security, and building access. The NAE/NIE unit is delivered with the operating system software already installed, but the user needs to provide site-specific data. Through a standard Web...

  • Page 5: Nae Ports

    Power The NAE requires 24 VAC power. The minimum input voltage for the NAE to operate properly is 20 VAC, but a minimum of 22 VAC is recommended to prevent nuisance power shutdown and startup routines during brownout conditions. When the input voltage falls...
  • Page 6 N2Bus Figure 3: N2 Terminal Block The Shield connection (S) on the N2 ports of the NAE is not connected to any Ground connection. S is an open terminal that can be used as a splice connection. The N2 A and N2 B terminal blocks are not interchangeable.
  • Page 7 Installing the NAE/NIE Technical Bulletin Use port A to connect directly to a Personal Computer (PC) serial port to browse to the NAE. See the Direct Connect and Dial-Up Connection on Windows® 2000 or Windows XP Operating Systems Application Note (LIT-1201639). Use Port B to connect with a VT100 terminal or PC using a VT100 terminal emulator because Port B outputs the device Internet Protocol (IP) address.

    226 x 332 x 96.5 mm (8.9 x 13.1 x 3.8 in.) not including mounting feet (Height x Width x Depth) Area required for mounting the NAE (minimum): 303 x 408 x 148 mm (12.0 x 16.1 x 5.8 in.).

  • Page 12: Batteries

    Data Protection Battery The NAE also contains a rechargeable and accessible battery to protect the data in the NAE volatile memory in case of power loss. If power fails, the NAE shuts down using battery power and saves field data to the flash memory.

  • Page 13: Installation Considerations

    NAE to promote good ventilation, LED visibility, and ease of service. • Do make sure the mounting surface can support the NAE and the added weight of the enclosure (if used). The NAE weighs approximately 2.8 kg (6.3 lb).
  • Page 14 NAE other than its power transformer and modem. • Do not mount the power transformer below the NAE. • Do not mount the NAE such that the enclosure wall or the transformer obstructs its venting. • Do understand that if you maintain temperature with a cooling fan, the reliability of the fan is not guaranteed and you may need to monitor the fan or temperature.

  • Page 15: Mounting Space

    See the NAE Help system for more information on diagnostics.) Note: No general guidance can be given about the number of heat-dissipating devices that can be mounted in a panel with the NAE. The acceptable combinations of devices and mounting locations can be determined only by testing the installation.

  • Page 18: System Re-Boot Switch

    Do not press the system RE-BOOT switch unless you have tried other reasonable means to fix the problem. When you press the system RE-BOOT switch, you lose all changes made to system data in the NAE since the last save, including audit data.

  • Page 19: Detailed Procedures

    2. Drill holes in the wall in the mounting feet locations you marked in Step 1. 3. Insert appropriate wall anchors in all four holes (if necessary) and inset screws into the top two holes and hang the NAE on the screws. Insert the screws into the last two mounting feet.
  • Page 20 2. Snap the DIN clips on the bottom of the unit to the outboard load position. 3. Hang the NAE on both DIN rails at the same time using the DIN rail hooks on the back of the unit (see Callout 17 in Figure 1).

  • Page 21: Installing The Data Protection Battery

    Installing the Data Protection Battery CAUTION: Risk of Property Damage. Before connecting line power to the NAE, check for proper wire and terminal plug placement. Improper electrical connections may damage the NAE. To install the data protection battery: Remove the battery from its packaging.

  • Page 22: Wiring The Nae

    To turn off the NAE, remove line power and wait for the POWER LED to go out. It takes approximately 1 to 6 minutes for the NAE to power down, depending on the amount of data to be backed up in the nonvolatile memory.
