RTU-292 Operations Manual

Mark all sides of the package:

FRAGILE - ELECTRONIC EQUIPMENT

Inspect the package prior to shipment to be sure it is properly marked and securely wrapped.

2.4 INSTALLATION OVERVIEW

Follow these four steps to properly install the RTU-292:

1.Provide mechanical mounting for the unit. (Rack slides or shelves are required for 19" rack mounting)

2.Provide the proper primary power for the unit.

3.Interconnect the unit with the radio and system as appropriate.

4.Check Section 2.8 to ensure that the unit is adjusted and configured as desired.

The RTU-292 is then ready to begin normal operation.

2.5 INSTALLATION CONSIDERATIONS

Careful attention to the following installation suggestions should result in the best unit/system performance. Figure 2.1 provides overall unit dimensions.

The RTU-292 must be installed in a structure that provides both protection from the weather and assurance of ambient temperatures between -20 and +55 degrees C. Since the unit is neither splashproof nor corrosion resistant, it must be protected from exposure to salt spray. When the unit is mounted in a cabinet with other heat-generating equipment, the use of a rack blower is suggested to keep the cabinet interior temperature rise to a minimum.

NOTE

Before actually installing the unit, read Section 2.8 to determine if any internal configuration options must be changed that would necessitate removal of the unit’s top cover.

The RTU-292 Radio/Telephone Interface is designed to be mounted in a standard EIA 19" wide rack by means of chassis slides (may be ordered from JPS) or on an L-bracket shelf. The unit weighs too much to be installed in a rack supported only by the front panel ears. Screws are provided in the accessory kit for securing the unit to the rack via the front panel.

Included in the Accessory Kit is a handset hanger; this hanger may be assembled to the unit’s front panel. Use the screws located below the logo and unit name. The hanger may also be assembled to the side of an equipment rack or elsewhere as desired.

2.5.1FCC PART 68 REGULATIONS

The RTU-292 has been designed to comply with FCC Part 68 regulations regarding equipment connected to telephone lines, but is not officially certified. If tested compliance to FCC Part 68 is required, external equipment can be installed between the RTU-292 and the telephone line to provide compliance.
