Section 2 INSTALLATION

2.1General

Installation of the VHF communication transceiver and the battery box depends on the type of aircraft and equipment involved, the instructions given in this section thus being only generally applicable.

2.2Pre-instailation check

2.2.1General

Prior to fitting the new system in the aircraft, the units must be checked according to the following procedure to establish whether they have been damaged in transit.

2.2.2Visual inspection

Prior to commissioning the equipment, carry out a visual inspection to establish any of the following deficiencies.

1.Soilage, dents, scratches, corrosion, broken fasteners, damaged paintwork on enclosures and parts thereof.

2.Soilage and scratches on the nameplate, front panel and markings.

3.Soilage, bends or broken-off pins, cracked plug and socket inserts.

4.Soilage and mechanical damage to rotary switches, LCD elements, knobs and pushbutton.

2.3Mechanical installation

2.3.1Mechanical installation VHF transceiver

The VHF transceiver is designed for incorporating in an aircraft instrument panel in behind panel installation. The circular cutout and the fastener holes must be drilled in accordance with the standard for small size instruments. Location must be min. 30 cm away from the magnetic compass of the aircraft to avoid the compass being affected by the transceiver. Dimensional requirements are shown in Fig. 2-4. Four DUZ fasteners (supply) are used to secure the unit.

2.3.2Mechanical installation of a temperature sensor

The VHF transceiver permits indication of temperatures in the range - 20° C to +100° C with the aid of an integral measuring circuit and a connected remote temperature sensor. The latter is located in accordance with the particular requirements and local conditions. The wiring can be seen from Fig. 2-5. Only use shielded flexed leads, noting the color coding of the connecting cables. The red lead must be connected to J 3101/8, the blue lead to J 3101/2. The shielding must be connected to pin 4 of J 3101.
