Wall Mounting

The Advance DataNET Hub should be:

•Installed in a location that is free from shock and vibration.

•Protected from direct sunlight and extremes of temperature.

•It is recommended that the DNH be mounted within a shelter. This prevents DNH from being exposed to outside environmental condi- tions.

The unit is designed for standard wall or Zone 1 wall installations, or 19- inch rack installations; see Chapter 1. Figures 1-5, 1-6 and 1-7. Shown below is a typical wall mount installation for NEC Division 2 or non-rated areas. The photo shows the unit wall mounted in an analyzer house. Note that the AC Power (Mains) breaker is located in close proximity of the unit. Also note the I/O connections to the DNH.
