Installation Instruction The Remote Unit, Extension Unit or Master Unit has to be mounted by proffessionel / special trained installer. 1.1. MECHANICAL INSTALLATION 1.1.1. General Read the health and safety warnings in section 1.3. 1. Do not install the unit in a way or at a place where the specifications outlined in the Environmental and Safety Specifications leaflet of the supplier are not met. 2. It is recommended to use the mounting hardware delivered by the supplier only. If different mounting hardware is used, the specifications for stationary use of the Remote Unit must not be exceeded. Note: Exceeding the specified load limits may cause the loss of warranty!

3. The unit is considerably heavy. Make sure that a suitable mounting surface is used. Ensure there is adequate manpower to handle the weight of the system. 4. Due to power dissipation, the Remote Unit may reach a very high temperature. Ensure sufficient airflow for ventilation. 5. When connecting and mounting the cables (RF, optical, mains, ...) ensure that no water can penetrate into the unit through these cables. 6. Also observe all additional rules or restrictions regarding mounting that depend on the type of Remote Unit. For details refer to section 7.2.2 Mechanical Specification. Install the unit vertically with the fan unit at the top. A maximum tilt angle of 25 from a vertical position must be kept, as in the following illustrations:

7. A spacing of 40 mm (1.58 inch) around the unit is required. 8. To ensure sufficient airflow when mounting the unit in enclosed spaces, two lid openings (one for the air inlet and the other for the air outlet) have to be provided. Do not block these air inlets and outlets when mounting the Remote Unit. The size of each opening must equal at least 12 x 12 cm

(144 cm2). Make sure, too, there is no thermal short circuit between the air inlet and air outlet. If any different or additional mounting material is used, ensure that the mounting remains as safe as the mounting designed by the manufacturer. Ensure that the static and dynamic strengths are adequate for the environmental conditions of the site. The mounting itself must not vibrate, swing or move in any way that might cause damage to the Remote Unit. Specified torques have to be observed for certain mounting procedures according to the following table:

The mounting procedures for a stand-alone Remote Unit without optional accessories are described and illustrated in the following sections. For further information regarding special mounting procedures including mounting of accessory equipment, please see separate manual. 1.2. ELECTRICAL INSTALLATION 1.2.1. General Read the health and safety warnings in section 1.3. 1. This unit contains dangerous voltages. Loss of life, severe personal injury, or property damage can be the result if the instructions contained in this manual are not followed. 2. It is compulsory to ground (earth) the unit before connecting the power supply. A grounding bolt is provided on the cabinet to connect the ground-bonding cable. 3. Although the Remote Unit is internally protected against over-voltage, it is strongly recommended to ground (earth) the antenna cables close to the antenna connectors of the Remote Unit for protection against atmospheric discharge. In areas with strong lightning, it is highly recommended to insert additional lightning protection. 4. If the mains connector of the Remote Unit is not easily accessible, a disconnect device in the mains power circuit must be provided within easy reach. 5. Before connecting or disconnecting the mains connector at the Remote Unit, ensure that mains power supply is disconnected. 6. Make sure that an appropriate circuit breaker acting as a disconnect device (as required by IEC/EN60950-1) and an overcurrent limiting device are connected between mains power and the Remote Unit. 7. A connection of mains supply to a power socket requires the power socket to be nearby the Remote Unit. 8. Incorrectly wired connections can destroy electrical and electronic components. 9. To avoid corrosion at the connectors caused by electrochemical processes, the material of the cable connectors must not cause a higher potential difference than 0.6 V (see electrochemical contact series). 10. Use an appropriate torque wrench for the coupling torque of N-type connectors (2 N-m / 20 in lb), with 13/16 in opening to tighten the N-type antenna connectors. For example, use torque wrench of item no. 244379 available from the Andrew e-catalog. Do NOT use your hands or any other tool

(e.g. a pair of pliers)! This might cause damage to the connector and lead to a malfunction of the Remote Unit. 11. For unstabilized electric networks, which frequently generate spikes, the use of a voltage limiting device is advised. 12. The unit complies with the surge requirement according to EN 61000-4-5 (fine protection); however, it is recommended to install an additional medium (via local supply connection) and/or coarse protection (external surge protection), depending on the individual application, in order to avoid damage caused by overcurrent. 13. Observe the labels on the front panels before connecting or disconnecting any cables. Note: The electrical installation has to be performed in accordance with the safety regulations of the local authorities. Due to safety reasons, the electrical installation must be performed by qualified personnel only. The repeater must not be opened. The maximum antenna height has to be 10 meters above ground. 1.3. HEALTH AND SAFETY WARNINGS 1. Only suitably qualified personnel are allowed to work on this unit and only after becoming familiar with all safety notices, installation, operation and maintenance procedures contained in this manual. 2. Read and obey all the warning labels attached to the unit. Make sure that the warning labels are kept in a legible condition and replace any missing or damaged labels. 3.
