Installation

2.0INSTALLATION

This section provides instructions for installing, mounting and connecting power and other cables to the OpenComms EM.

2.1Installation Considerations

The OpenComms EM must be installed indoors where electrical service is available. The unit should be placed where it can be easily accessed for connecting the unit to a modem, a computer or a network hub and, if used, serial devices.

The unit may either be mounted on a wall or be placed on a surface, depending on the user’s applica- tion and the location of equipment to be connected and monitored. Consider the length of the sensor cable and the distance to the monitored area when deciding where to place the OpenComms EM, whether you use the 1-ft. (0.3m) cable provided with the unit or the optional 15-ft. (4.6m) cable that may be purchased separately.

2.1.1Unpacking and Preliminary Inspection

•Before unpacking the OpenComms EM, inspect the shipping carton for damage or signs of mis- handling, such as gashes or holes in the carton or severely flattened corners.

•Open the shipping carton carefully. Use care to avoid puncturing the container with sharp objects that might damage the contents.

•Inspect the OpenComms EM and all included components for damage. See Table 3 for a list of items that should be included with each model.

•If any damage from shipping or mishandling is observed, immediately file a damage claim with the shipping agency and forward a copy to:
