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 chapter 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 only to use the mounting hardware delivered by the supplier. 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 as specified in the individual mounting procedures. 5. When connecting and mounting the cables (RF, optical, mains, ...) ensure 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 chapter 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 17 x 17 cm (290 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: Type Tallow-drop screws Hex nuts Spacing bolts PG (plastic) PG (aluminium) Thread M 4 M 8 M 4 M 8 PG 13.5 PG 29 Specified torques 3.3 Nm 27 Nm 2.3 Nm 27 Nm 3.75 Nm 10 Nm Specified torques  Note: To avoid damage when mounting the unit, always make sure that the M8 washers (DIN9021 or DIN125 depending on the mounting kit) are placed behind and in front of the mounting drillings of the unit. 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 chapter 1.1. 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 the unit before connecting 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 overvoltage, it is strongly recommended to 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 strongly 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 circuit must be provided within easy reach. 5. Before connecting or disconnecting the mains connector at the Remote Unit, ensure that mains supply is disconnected. 6. Make sure that an appropriate branch circuit breaker and an overcurrent limiting device are connected between mains and Remote Unit. 7. An external circuit breaker is mandatory as disconnect device. This circuit breaker should be readily available for the operator. For the U.S. and Canada, installation has to be done in accordance with the NEC (National Electronic Code). The external circuit breaker has to be a branch circuit breaker rated 20 A for 110 Vac mains. 8. A field wiring box with conduit must be used for the installation. Use a wire harness rated for AC mains with at least AWG14 size. 9. A connection of mains supply to a power socket requires the power socket to be nearby the Remote Unit. 10. Incorrectly wired connections can destroy electrical and electronic components. 11. 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). 12. Use an appropriate torque wrench for the coupling torque (25 N-m / 19 ft lb) of 7/16-DIN connectors with 1 ¼-inch opening to tighten the 7/16-type antenna connectors. For example, use torque wrench of item no. 244377 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. 13. For unstabilized electric networks which frequently generate spikes, it is advised to use a voltage limiting device.
14. 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. 15. Observe the labels on the front panels before connecting or disconnecting any cables! 1.3. HEALTH AND SAFETY WARNINGS 1. Only suitably qualified personnel is 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.
